The vulnerability occurs because the application fails to adequately sanitize user-supplied input when configuring the PGP binary path and command-line options. An attacker possessing administrator-level privileges within the OTRS platform can leverage this flaw to inject arbitrary shell commands.\u003c/p\u003e\n\u003cp\u003eThe malicious payload is concatenated directly into a system command executed by the underlying web server process. Because the application processes these configuration values during ticket operations, the injected commands run with the privileges of the web server user. This vulnerability represents a significant risk for organizations that allow multiple administrators or have been compromised by a lower-privileged actor looking to escalate control over the web server environment.\u003c/p\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation allows an authenticated administrator to achieve arbitrary command execution on the host server.
