Technical ContextAI · show details

This vulnerability is classified as Unrestricted File Upload (CWE-434), which allows attackers to upload malicious files that can be executed on the server. 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. Affected products include: Otrs. Version information: through 5.0.24.

Attack Technique

Malicious file upload attacks exploit insufficient validation when web applications accept user-provided files.

Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
