First Published: 2020 November 4 16:00 GMT
Last Updated: 2021 May 21 18:06 GMT
Version 4.1: Final
Workarounds: Yes
Cisco Bug IDs: CSCvv30103
CVE Names: CVE-2020-3556
CWEs: CWE-20
Summary
o A vulnerability in the interprocess communication (IPC) channel of Cisco
AnyConnect Secure Mobility Client Software could allow an authenticated,
local attacker to cause a targeted AnyConnect user to execute a malicious
script.
The vulnerability is due to a lack of authentication to the IPC listener.
An attacker could exploit this vulnerability by sending crafted IPC
messages to the AnyConnect client IPC listener. A successful exploit could
allow an attacker to cause the targeted AnyConnect user to execute a
script. This script would execute with the privileges of the targeted
AnyConnect user.
Note: To successfully exploit this vulnerability, an attacker would need
all of the following:
Valid user credentials on the system on which the AnyConnect client is
being run by the targeted user.
To be able to log in to that system while the targeted user either has
an active AnyConnect session established or establishes a new
AnyConnect session.
To be able to execute code on that system.
Cisco has released software updates that address this vulnerability. There
are workarounds that address this vulnerability.
This advisory is available at the following link:
https://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-anyconnect-ipc-KfQO9QhK
Affected Products
o Vulnerable Products
This vulnerability affects all releases of Cisco AnyConnect Secure Mobility
Client Software earlier than Release 4.10.00093 for the following platforms
if they have a vulnerable configuration:
AnyConnect Secure Mobility Client for Windows
AnyConnect Secure Mobility Client for MacOS
AnyConnect Secure Mobility Client for Linux
The following subsections describe how to determine vulnerability for
specific releases of Cisco AnyConnect Secure Mobility Client Software. The
release of Cisco AnyConnect Secure Mobility Client Software that is running
on the end machine determines which configurations the user must check.
The configuration settings discussed in the following subsections are in
the AnyConnectLocalPolicy.xml file. This file is in the following
locations:
Windows::ProgramDataCiscoCisco AnyConnect Secure
Mobility Client
macOS: /opt/cisco/anyconnect/
Linux: /opt/cisco/anyconnect/
Cisco AnyConnect Secure Mobility Client Software Releases 4.9.04053,
4.9.05042, and 4.9.06037
The vulnerability described in this advisory affects Cisco AnyConnect
Secure Mobility Client Software releases 4.9.04053, 4.9.05042, and
4.9.06037 if RestrictScriptWebDeploy is set to the default value of false .
To verify the RestrictScriptWebDeploy configuration setting on a VPN client
system, open the AnyConnectLocalPolicy.xml file and look for the following
line:
false
If RestrictScriptWebDeploy is set to false, RestrictScriptWebDeploy is
disabled and the device is affected by this vulnerability. If
RestrictScriptWebDeploy is set to true , RestrictScriptWebDeploy is enabled
and the device is not affected by this vulnerability.
See the Workarounds section for additional optional but recommended
settings.
Cisco AnyConnect Secure Mobility Client Software Releases Earlier than
Release 4.9.04053
The vulnerability described in this advisory affects all releases of Cisco
AnyConnect Secure Mobility Client Software earlier than Release 4.9.04053
if BypassDownloader is set to the default value of false.
To verify the BypassDownloader configuration setting on a VPN client
system, open the AnyConnectLocalPolicy.xml file and look for the following
line:
false
If BypassDownloader is set to false , BypassDownloader is disabled and the
device is affected by this vulnerability. If BypassDownloader is set to
true, BypassDownloader is enabled and the device is not affected by this
vulnerability.
Note: Setting BypassDownloader to true is not a recommended configuration.
See the Workarounds section for more details.
Products Confirmed Not Vulnerable
Only products listed in the Vulnerable Products section of this advisory
are known to be affected by this vulnerability.
This vulnerability does not affect Cisco AnyConnect Secure Mobility Client
for Apple iOS or Android platforms or for the Universal Windows Platform.
Details
o Details about the vulnerability are as follows.
This vulnerability is not exploitable on laptops used by a single user,
but instead requires valid logins for multiple users on the end-user
device.
This vulnerability is not remotely exploitable, as it requires local
credentials on the end-user device for the attacker to take action on
the local system.
This vulnerability is not a privilege elevation exploit. The scripts
run at the user level by default. If the local AnyConnect user manually
raises the privilege of the User Interface process, the scripts would
run at elevated privileges.
This vulnerability’s CVSS score is high because, for configurations
where the vulnerability is exploitable, it allows one user access to
another user’s data and execution space.
Workarounds
o Workarounds that address this vulnerability were introduced in Cisco bug ID
CSCvw48062 via new configuration settings. The new settings are available
in releases 4.9.04053 and later. Cisco recommends using additional settings
that were introduced in Release 4.10.00093 instead of using the settings
introduced in 4.9.04053.
The settings introduced in 4.10.00093 allow connections to trusted headends
only, without any functionality loss. Additional information about the new
settings is in the Recommendations section of this advisory.
Cisco AnyConnect Secure Mobility Client Software Release 4.10.00093
Releases 4.10.00093 and later contain the fix for Cisco bug ID CSCvv30103
with no additional configuration required. See the Recommendations section
for additional optional but recommended settings.
Upgrade instructions for systems where workarounds were previously applied
This section is relevant only to customers that had previously applied the
workaround settings for releases 4.9.04053, 4.9.05042, or 4.9.06037 or
mitigation settings for releases earlier than Release 4.9.04053. If the
workarounds or mitigations listed on this advisory were not previously
used, use the normal upgrade process. More information about the normal
upgrade process is in the Release Notes or Configuration Guide .
The following instructions describe how to upgrade to Release 4.10.00093
and remove the previously applied settings in the AnyConnectLocalPolicy.xml
file. This file is in the following locations:

required. If these settings remain true , files must be distributed using
an out-of-band deployment method.
Cisco AnyConnect Secure Mobility Client Software Releases 4.9.04053,
4.9.05042, and 4.9.06037
For customers who have already applied the RestrictScriptWebDeploy
workaround
For customers using Release 4.9.04053, 4.9.05042, or 4.9.06037 who have
already applied the RestrictScriptWebDeploy, RestrictHelpWebDeploy,
RestrictResourceWebDeploy, RestrictLocalizationWebDeploy workarounds,
nothing further needs to be done to help ensure protection against
exploitation of this vulnerability.
To restore full functionality to the product, customers should upgrade to
Release 4.10.00093 and apply the recommended settings shown in the
Recommendations section. After full functionality is restored, customers
can once again deploy files from the headend instead of using an
out-of-band deployment method.
For customers who cannot upgrade to Release 4.10.00093 or later
For customers using Release 4.9.04053, 4.9.05042, or 4.9.06037 who cannot
upgrade to Release 4.10.00093 or later, the recommended workaround for
these releases is to edit the AnyConnectLocalPolicy.xml file to set
RestrictScriptWebDeploy to true and ensure that BypassDownloader is set to
false . The new AnyConnectLocalPolicy.xml file would then be deployed to
end machines using an out-of-band method of deployment.
There are additional configuration settings for releases 4.9.04053,
4.9.05042, and 4.9.06037 that are strongly recommended for increased
protection. The full set of custom web-deploy restrictions is listed below.
For more details about the new configuration settings and implications of
their use, refer to the Release Notes or Cisco bug ID CSCvw48062 . These
settings would allow profile updates and future software upgrades while
helping to protect against exploitation of this vulnerability.
RestrictScriptWebDeploy
RestrictHelpWebDeploy
RestrictResourceWebDeploy
RestrictLocalizationWebDeploy
The following procedure is for editing the policy on a local machine. In
most deployment scenarios, the modification would be done to the
AnyConnectLocalPolicy.xml file and then deployed to all client machines
using an out-of-band method of deployment such as an enterprise software
management system. Any modifications to the AnyConnectLocalPolicy.xml file
must be done with sudo or admin rights.
1. Find the AnyConnectLocalPolicy.xml file on the client machine. This
file is in the following locations:
Windows::ProgramDataCiscoCisco AnyConnect Secure
Mobility Client
macOS:/opt/cisco/anyconnect/
Linux:/opt/cisco/anyconnect/
2. Open the AnyConnectLocalPolicy.xml file in a text editor and look for
the following lines:
false
false
false
false
3. Change that setting to true , as shown in the following example:
true
true
true
true
4. Verify that the BypassDownloader setting is correct by looking for the
following line:
false
5. If the BypassDownloader setting is true , change it to false , as shown
in the following example:
false
6. Save the file to the original location. The network paths are noted
above.
7. Restart the VPN Agent service or reboot the client machine.
Cisco AnyConnect Secure Mobility Client Software Earlier than Release
4.9.04053
For customers who have already applied the BypassDownloader mitigation
For customers using releases earlier than Release 4.9.04053 who have
already applied the BypassDownloader mitigation, nothing further needs to
be done to enable protection against exploitation of this vulnerability.
Because this mitigation is not recommended , customers could upgrade to
Release 4.10.00093 and apply the recommended settings shown in the
Recommendations section.
For customers who cannot upgrade to Release 4.10.00093 or later
For customers using releases earlier than Release 4.9.04053 who cannot
upgrade to Release 4.10.00093 or later and/or do not require updated
content on the VPN headend device to be downloaded to the client, enabling
the BypassDownloader setting is a possible mitigation.
Warning: Changing the BypassDownloader setting is not recommended in most
customer environments. If the BypassDownloader is set to true , VPN users
could be refused a connection from the VPN headend if their local VPN XML
profiles are out of date with what is configured on the VPN headend.
Note: Enabling the BypassDownloader setting can be done only out-of-band on
the client devices and has a couple of implications:
All future updates to either Cisco AnyConnect Secure Mobility Client
Software or the AnyConnect profile would have to be done out-of-band.
AnyConnect will no longer download updated content from the headend
device.
AnyConnect profiles would still need to be in sync between the headend
device and the client. If the profiles are not in sync, the VPN
connection could be established with default settings instead of with
settings on the headend or client. The VPN headend could also refuse
the connection.
The procedure that follows is for editing the policy on a local machine. In
most deployment scenarios, the modification would be done to the
AnyConnectLocalPolicy.xml file and then deployed to all client machines
using an out-of-band method of deployment such as an enterprise software
management system. Any modifications to the AnyConnectLocalPolicy.xml file
must be done with sudo or admin rights.
1. Find the AnyConnectLocalPolicy.xml file on the client machine. This
file is in the following locations:
Windows::ProgramDataCiscoCisco AnyConnect Secure
Mobility Client
macOS:/opt/cisco/anyconnect/
Linux: /opt/cisco/anyconnect/
2. Open the AnyConnectLocalPolicy.xml file in a text editor and look for
the following line:
false
3. Change that setting to true , as shown in the following example:
true
4. Save the file to the original location. The network paths are noted
above.
5. Restart the VPN Agent service or reboot the client machine.
Fixed Software
o Cisco has released free software updates that address the vulnerability
described in this advisory. Customers may only install and expect support
for software versions and feature sets for which they have purchased a
license. By installing, downloading, accessing, or otherwise using such
software upgrades, customers agree to follow the terms of the Cisco

AusCERT Security Bulletin Summary
———————————
Product: Junos OS
Publisher: Juniper Networks
Operating System: Juniper
Impact/Access: Execute Arbitrary Code/Commands — Remote/Unauthenticated
Denial of Service — Remote/Unauthenticated
Resolution: Patch/Upgrade
CVE Names: CVE-2021-0254
Original Bulletin:

2021-04 Security Bulletin: Junos OS: Remote code execution vulnerability in overlayd service (CVE-2021-0254)
Article ID : JSA11147
Last Updated: 21 May 2021
Version : 5.0
Product Affected:
This issue affects Junos OS 15.1, 17.3, 17.4, 18.1, 18.2, 18.3, 18.4, 19.1,
19.2, 19.3, 19.4, 20.1, 20.2, 20.3.
Problem:
A buffer size validation vulnerability in the overlayd service of Juniper
Networks Junos OS may allow an unauthenticated remote attacker to send
specially crafted packets to the device, triggering a partial Denial of Service
(DoS) condition, or leading to remote code execution (RCE). Continued receipt
and processing of these packets will sustain the partial DoS.
The overlayd daemon handles Overlay OAM packets, such as ping and traceroute,
sent to the overlay. The service runs as root by default and listens for UDP
connections on port 4789. This issue results from improper buffer size
validation, which can lead to a buffer overflow. Unauthenticated attackers can
send specially crafted packets to trigger this vulnerability, resulting in
possible remote code execution.
overlayd runs by default on MX Series, QFX Series, and certain ACX Series (e.g.
ACX5445, but not the ACX5048) platforms.
Platforms such as the SRX Series and PTX Series do not run overlayd and are
therefore not vulnerable to this issue.
Additionally, while some EX Series platforms do run overlayd, no model of EX
Series switch has been shown to be exploitable to this vulnerability.
To summarize, if overlayd is not running on a particular platform, the system
is not vulnerable to this issue. Users can confirm the presence of the overlayd
process by issuing the following command:
user@junos> show system processes extensive | match overlay
2030 root 4 0 28984K 5004K kqread 0:00 0.00% overlayd
This issue affects Juniper Networks Junos OS:
o 15.1 versions prior to 15.1R7-S9;
o 17.3 versions prior to 17.3R3-S11;
o 17.4 versions prior to 17.4R2-S13, 17.4R3-S4;

o 20.2 versions prior to 20.2R2, 20.2R2-S1, 20.2R3;
o 20.3 versions prior to 20.3R1-S1.
There is no minimum configuration required to be vulnerable to this issue.
Juniper SIRT is not aware of any malicious exploitation of this vulnerability.
This issue was discovered during external security research.
This issue has been assigned CVE-2021-0254 .
Solution:
The following software releases have been updated to resolve this specific
issue: Junos OS 15.1R7-S9, 17.3R3-S11, 17.4R2-S13, 17.4R3-S4, 18.1R3-S12,
18.2R2-S8, 18.2R3-S7, 18.3R3-S4, 18.4R1-S8, 18.4R2-S7, 18.4R3-S7, 19.1R2-S2,
19.1R3-S4, 19.2R1-S6, 19.2R3-S2, 19.3R3-S1, 19.4R2-S4, 19.4R3-S1, 20.1R2-S1,
20.1R3, 20.2R2, 20.2R2-S1, 20.2R3, 20.3R1-S1, 20.4R1, and all subsequent
releases.
This fix has also been proactively committed into other releases that might not
be vulnerable to this issue.
This issue is being tracked as 1548415 .
Workaround:
Two methods exist to mitigate this issue:
1. Limit the exploitable attack surface of critical infrastructure networking
equipment by using access lists or firewall filters to limit access to the
device via UDP only from trusted, administrative networks or hosts.
2. Disable Overlay OAM packet via the configuration command: ‘ set system
processes overlay-ping-traceroute disable ‘
Implementation:
Software releases or updates are available for download at https://
support.juniper.net/support/downloads/
