Product Affected: This issue affects Junos OS Evolved 23.1R1-EVO through before
23.2R2-EVO with Paragon Active Assurance Test Agent installed on ACX Series.
Severity Level: Medium
CVSS Score: CVSS 3.1
Problem:
A Cleartext Storage in a File on Disk vulnerability in Juniper Networks Junos
OS Evolved ACX Series devices using the Paragon Active Assurance Test Agent
software installed on network devices allows a local, authenticated attacker
with high privileges to read all other users login credentials.
This issue affects only Juniper Networks Junos OS Evolved ACX Series devices
using the Paragon Active Assurance Test Agent software installed on these
devices from 23.1R1-EVO through 23.2R2-EVO.
This issue does not affect releases before 23.1R1-EVO.
Required configuration for exposure:
Potentially affected devices are those which use the following configuration
statement:
<codeph>test-agent</codeph>
Located at the hierarchy level:
<codeph>[edit services pas]</codeph>
Therefore verify that the following minimal configuration statement in the
Junos device exists:
[services pas]
And verify that the agent is running on the device.
Solution:
The following software releases have been updated to resolve this specific
issue:
Junos OS Evolved: 23.2R2-EVO, 23.3R1-EVO, and all subsequent releases.
Note: Before you upgrade the system software from Junos OS Evolved Release
23.2R1 to a later release, you must uninstall the test agent using the request
services paa uninstall command. See the product documentation for upgrade
procedures and coordinate with JTAC for support.
This issue is being tracked as 1728816 which is visible on the Customer Support
website.
Note: Juniper SIRT's policy is not to evaluate releases which are beyond End of
Engineering (EOE) or End of Life (EOL).
Workaround:
There are no known workarounds for this issue.
Devices using the following deprecated operational mode command are unaffected:
<codeph>request services paa install</codeph>
