KeePassXC < 2.7.12 Local Privilege Escalation

high Nessus Plugin ID 303197

Language:

Synopsis

The remote host is missing a security update.

Description

The version of KeePassXC installed on the remote Windows host is prior to 2.7.12. It is, therefore, affected by a local privilege escalation vulnerability due to loading OpenSSL configuration from an unsecured location. A local attacker with low-privileged access could leverage this vulnerability to escalate privileges and execute arbitrary code in the context of KeePassXC when run by a target user on the system.

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 KeePassXC version 2.7.12 or later.
