In short
Plesk's application search feature doesn't properly clean user input before using it in database queries, allowing a low-level user to run commands on the server and gain admin privileges.
Technical detail
XPath injection in APS Application Catalog search allows authenticated, low-privileged users to manipulate XPath queries through unsanitized input, enabling arbitrary OS command execution and local privilege escalation to system-level access.
Summary generated and translated by AI from the official description.
Plesk contains an XPath injection vulnerability in the APS Application Catalog search functionality, where user-supplied input is interpolated into XPath queries without proper sanitization. This allows an authenticated, low-privileged user to execute arbitrary operating system commands on the server, resulting in local privilege escalation.
