CVE-2019-14451
When this is combined with CVE-2019-14450, an attacker can upload an "external command" configuration as a printer configuration, and achieve remote code execution.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.45%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
RepetierServer.exe in Repetier-Server 0.8 through 0.91 does not properly validate the XML data structure provided when uploading a new printer configuration. When this is combined with CVE-2019-14450, 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.
