Name of the Vulnerable Software and Affected Versions Ivanti Avalanche version 6.3.3.101

Description This issue allows remote attackers to execute arbitrary code on affected installations. Although authentication is required to exploit this issue, the existing authentication mechanism can be bypassed. The specific flaw exists within the DeviceLogResource class and results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this issue to execute code in the context of the service account.

Recommendations For Ivanti Avalanche version 6.3.3.101, consider disabling the DeviceLogResource class until a patch is available to prevent potential exploitation. Restrict access to sensitive areas of the system to minimize the risk of arbitrary code execution. At the moment, there is no information about a newer version that contains a fix for this issue.
