CyberVault Technical Summary

Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2018-7567 impacting otrs otrs. Evaluated with CVSS Base Score of 7.2 (HIGH).

Original NVD Description

Source: NIST NVD
In the Admin Package Manager in Open Ticket Request System (OTRS) 5.0.0 through 5.0.24 and 6.0.0 through 6.0.1, authenticated admins are able to exploit a Blind Remote Code Execution vulnerability by loading a crafted opm file with an embedded CodeInstall element to execute a command on the server during package installation. NOTE: the vendor disputes this issue stating "the behaviour is as designed and needed for different packages to be installed", "there is a security warning if the package is not verified by OTRS Group", and "there is the possibility and responsibility of an admin to check packages before installation which is possible as they are not binary.
