It carries a CVSS score of 9.8 (reachable over the network; low attack complexity; high confidentiality, integrity, availability impact). Exploitation requires no authentication. The issue is fixed in version 4.963; sites on affected versions should update now. Disclosed November 2024, reported by Foxyyy.
Vulnerability Overview
The WPLMS Learning Management System for WordPress, WordPress LMS theme for WordPress is vulnerable to arbitrary file read and deletion due to insufficient file path validation and permissions checks in the readfile and unlink functions in all versions up to, and including, 4.962. This makes it possible for unauthenticated attackers to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). The theme is vulnerable even when it is not activated.
Technical Analysis
The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no privileges on the target site, and no interaction from a victim user. A successful exploit has high impact on confidentiality, integrity, availability — full site compromise territory.
CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Reaching this weakness in WPLMS Learning Management System for WordPress, WordPress LMS <= 4.962 takes no account at all. Path traversal happens when user-controlled text is used to build a filesystem path without being constrained to an intended directory, so sequences like ../ walk the resolved path somewhere else.
Depending on the operation, it means reading files outside the intended folder — wp-config.php being the usual target — or writing to and deleting paths the web server can touch. For WPLMS Learning Management System for WordPress, WordPress LMS the fix is 4.963: builds <= 4.962 are affected, anything from 4.963 onward is not.
Remediation
Update to version 4.963, or a newer patched version
