Summary
A client-side path traversal vulnerability was discovered in the web management interface front-end due to missing validation of an input parameter.
Impact
An authenticated user with limited privileges can craft a malicious URL which, if visited by an authenticated victim, leads to a Cross-Site Scripting (XSS) attack. Via XSS, an attacker may be able to perform unauthorized actions on the web management interface on behalf of legitimate users, gather sensitive information, or have other unspecified impacts on the victims' browsers.
Affected Products
Guardian, CMC < v25.2.0
Workarounds and Mitigations
Use internal firewall features to limit access to the web management interface. Review all accounts with access to it and delete unnecessary ones. Apply care when opening untrusted links or visiting external websites while an authenticated session to the web management interface is established.
Solutions
Upgrade to v25.2.0 or later.
