Vulnerability Description
The Policy Auditor web-based user interface incorrectly sanitized web script or
HTML in the profileNodeID and UIDs response parameters allowing an attacker to
obtain session token or login credentials and conduct arbitrary cross-domain
requests. Access to the user interface is expected to be restricted to the
local network, meaning an attacker would need to be on your network.
1. CVE-2021-31851
A Reflected Cross-Site Scripting vulnerability in McAfee Policy Auditor
prior to 6.5.2 allows a remote unauthenticated attacker to inject arbitrary
web script or HTML via the profileNodeID request parameters. The malicious
script is reflected unmodified into the Policy Auditor web-based interface
which could lead to the extraction of end user session token or login
credentials. These may be used to access additional security-critical
applications or conduct arbitrary cross-domain requests.
NVD CVE-2021-31851
MITRE CVE-2021-31851
2. CVE-2021-31852
A Reflected Cross-Site Scripting vulnerability in McAfee Policy Auditor
prior to 6.5.2 allows a remote unauthenticated attacker to inject arbitrary
web script or HTML via the UID request parameter. The malicious script is
reflected unmodified into the Policy Auditor web-based interface which
could lead to the extract of end user session token or login credentials.
These may be used to access additional security-critical applications or
conduct arbitrary cross-domain requests.
NVD CVE-2021-31852
MITRE CVE-2021-31852
Remediation
To remediate this issue, customers should install or update to the Policy
Auditor 6.5.2 November 2021 release.

What is CVSS
Common Vulnerability Scoring System (CVSS) is the result of the National
Infrastructure Advisory Council's effort to standardize a system of assessing
the criticality of a vulnerability. This system offers an unbiased criticality
score between 0 and 10 that customers can use to judge how critical a
vulnerability is and plan accordingly. For more information, visit the CVSS
website .
When calculating CVSS scores, McAfee Enterprise has adopted a philosophy that
fosters consistency and repeatability. Our guiding principle for CVSS scoring
is to score the exploit under consideration by itself. We consider only the
immediate and direct impact of the exploit under consideration. We don't factor
into a score any potential follow-on exploits that might be made possible by
the successful exploitation of the issue being scored.

Where can I find a list of all Security Bulletins
All Security Bulletins are published on our external PSIRT website . To see
Security Bulletins for McAfee Enterprise products on this website, click
Enterprise Security Bulletins . Security Bulletins are retired (removed) once a
product is both End of Sale and End of Support (End of Life).
How do I report a product vulnerability to McAfee Enterprise
If you have information about a security issue or vulnerability with a McAfee
Enterprise product, go to the PSIRT website , click Report a Security
Vulnerability , and follow the instructions.
How does McAfee Enterprise respond to this and any other reported security
flaws
Our key priority is the security of our customers. If a vulnerability is found
within any McAfee Enterprise software or services, we work closely with the
relevant security software development team to ensure the rapid and effective
development of a fix and communication plan.
McAfee Enterprise only publishes Security Bulletins if they include something
actionable such as a workaround, mitigation, version update, or hotfix.
Otherwise, we would simply be informing the hacker community that our products
are a target, putting our customers at greater risk. For products that are
updated automatically, a non-actionable Security Bulletin might be published to
acknowledge the discoverer.
View our PSIRT policy on the PSIRT website by clicking About PSIRT .
