Siemens Automation License Manager 5.x < 6.0.8 Privilege Escalation (SSA-388646)

high Nessus Plugin ID 139606
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote host has software installed that is affected by a privilege escalation vulnerability.

Description

The version of Siemens Automation License Manager installed on the remote host is version 5.x prior to 6.0.8. It is, therefore, affected by a privilege escalation vulnerability due to improper validation of user privileges when executing some operations. An authenticated, local attacker could exploit this issue to modify arbitrary files that should be protected against writing.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Siemens Automation License Manager 6.0+SP8 (6.0.8) or later.
