medium Nessus Plugin ID 181595


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


The version of Adobe Lightroom Classic installed on the remote host is prior to 10.4. It is, therefore, affected by privilege escalation vulnerability. The vulnerability exists due to creation of temporary file in directory with incorrect permissions, which leads to security restrictions bypass and privilege escalation.
