A directory traversal vulnerability was discovered in RepetierServer.exe in Repetier-Server 0.8 through 0.91 that allows for the creation of a user controlled XML file at an unintended location. When this is combined with CVE-2019-14451, an attacker can upload an "external command" configuration as a printer configuration, and achieve remote code execution. After exploitation, loading of the external command configuration is dependent on a system reboot or service restart.

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.

⚠️ GitHub proofs of concept are not verified: some are fake or contain malware. Never run them outside an isolated lab.
