Technical details
An XPath injection vulnerability exists in the APS Application Catalog search functionality of Plesk. The flaw is caused by improper sanitization of user-supplied input before it is interpolated into XPath queries (CWE-643). An authenticated, low-privileged attacker can exploit this by submitting crafted search queries to execute arbitrary operating system commands on the server. This leads to local privilege escalation and a full system compromise. The vulnerability is reachable over the network and has been assigned a CVSS score of 9.9 due to the high impact on confidentiality, integrity, and availability.
