Name of the Vulnerable Software and Affected Versions WhiteSource Application Vulnerability Management (AVM) versions prior to 20.4.1

Description The issue allows log injection via a %0A%0D substring in the idp parameter to the "/saml/login" API endpoint. This can close the current log and create a new log with one line of data, also enabling the insertion of malicious data and false entries.

Recommendations For versions prior to 20.4.1, update to version 20.4.1 or later to resolve the issue. As a temporary workaround, consider restricting access to the "/saml/login" API endpoint to minimize the risk of exploitation, and avoid using the idp parameter until the issue is resolved.
