Name of the Vulnerable Software and Affected Versions Ivanti Avalanche version 6.3.2.3490

Description This issue allows remote attackers to bypass authentication on affected installations.

Recommendations For Ivanti Avalanche version 6.3.2.3490, consider disabling the AvalancheDaoSupport class temporarily until a patch is available to prevent exploitation. Restrict access to sensitive areas of the system to minimize the risk of unauthorized access. Avoid using user-supplied strings in SQL queries until the issue is resolved.
