Name of the Vulnerable Software and Affected Versions Tenable Appliance versions 3.5 through 4.4.0 Tenable Appliance versions prior to 3.5

Description The issue is related to a flaw in the simpleupload.py script in the Web UI, which allows a remote attacker to inject arbitrary commands by manipulating the tns appliance session user parameter. This can enable the attacker to execute commands remotely.

Recommendations For Tenable Appliance versions 3.5 through 4.4.0, consider disabling the simpleupload.py script in the Web UI until a patch is available. For Tenable Appliance versions prior to 3.5, restrict access to the Web UI to minimize the risk of exploitation. As a temporary workaround, avoid using the tns appliance session user parameter in the affected API endpoint until the issue is resolved.
