Improper Control of Filename for Include/Require Statement in PHP Program ('PHP Remote File Inclusion') vulnerability in Case-Themes CTUsers allows PHP Local File Inclusion. This issue affects CTUsers: from n/a through 1.0.0.
AnalysisAI
Local file inclusion in CTUsers WordPress plugin up to 1.0.0 allows unauthenticated attackers to include arbitrary local files via a crafted request. Exploitation requires user interaction and high attack complexity, but can lead to full compromise of the affected server, including disclosure of sensitive data or code execution. The vulnerability is not known to be actively exploited and has a low EPSS probability score.
Technical ContextAI
The vulnerability stems from improper validation of user-supplied input in PHP include/require statements (CWE-98) within the CTUsers plugin. Attackers can manipulate the file path parameter to include arbitrary local files, a typical outcome of insufficient sanitization in PHP-based web applications. The affected product, CTUsers (CPE not explicitly listed but derived from the WordPress plugin slug 'ctuser'), versions up to 1.0.0, is susceptible. The underlying weakness is the failure to properly control the filename argument in file inclusion functions, enabling path traversal and LFI.
RemediationAI
No vendor-released patch is currently identified. Users should remove the CTUsers plugin until a fix is available. If removal is not feasible, restrict access to the WordPress admin area and deploy a web application firewall (WAF) with rules to block path traversal and LFI attempts on the plugin’s endpoints. Monitor for any unusual file inclusion activities and consider disabling the plugin’s vulnerable feature if identified, though this may break functionality. Refer to the Patchstack advisory for updates.
