Technical details
A path traversal vulnerability (CWE-22) exists in Textpattern CMS up to version 4.9.1. The flaw is located within the mt_uploadImage function in the rpc/TXP_RPCServer.php file, which handles XML-RPC requests. An attacker can manipulate the 'file.name' argument to bypass directory restrictions. Exploitation requires low-level authentication (PR:L) and can be performed over the network. Successful exploitation allows an attacker to upload files to arbitrary locations on the server filesystem, potentially leading to remote code execution or data exposure depending on the server configuration. A fix is expected in an upcoming release.
