Detailsinfo

A vulnerability, which was classified as critical, was found in Matrix42 Matrix42 Empirum before up to 25.4/26.1. Affected is some unknown functionality of the file PBackupVSS.exe of the component IPC Handler. The manipulation with an unknown input leads to a untrusted search path vulnerability.

The product searches for critical resources using an externally-supplied search path that can point to resources that are not under the product's direct control. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

PBackupVSS.exe in Matrix42 Empirum before 25.5 and 26.x before 26.2 creates a named pipe (\\.\pipe\PBackupVSS) with a DACL that grants GENERIC_READ and GENERIC_WRITE permissions to all authenticated users. A low-privileged local attacker can connect to this pipe and send crafted IPC messages to trigger execution of arbitrary commands with SYSTEM privileges via an untrusted search path. This allows privilege escalation by placing a malicious shadow.exe in a controlled working directory.
