CVE-2023-22855Public exploitNetwork attack vector

Unauthenticated code execution via remote T4 inclusion

Published Feb 15, 2023 · Updated Mar 19, 2025

Code injection in Kardex Mlog MCC 5.7.12+0-a203c2a213-master allows remote attackers to execute arbitrary code via an HTTP request. The port 8088 web interface passes a user-controlled path to GetFile, where Path.Combine accepts local or SMB paths and .t4 content reaches the Mono T4 renderer. Network access to port 8088 and attacker-hosted SMB content are sufficient for arbitrary C# execution in the service context.
