EIP tracks 1 public exploit for CVE-2026-23697. PoCs published by JivaSecurity.

AI-analyzed exploit summary This PoC exploits an authenticated remote code execution vulnerability in Vtiger CRM 8.3.0 via a .phar file upload bypass, combined with misconfigured Apache directory listing and .htaccess rules. The exploit chains authentication, file upload, and directory traversal to achieve command execution.

Vtiger CRM before 8.4.0 contains an authenticated file upload vulnerability that allows low-privileged users to achieve remote code execution by uploading a .phar file containing arbitrary PHP code through the Documents module, bypassing the extension denylist in config.inc.php which omits the .phar extension. The uploaded file is stored with its original .phar extension under the web-accessible storage directory, and a misconfigured .htaccess using Apache 2.2 syntax is silently ignored on Apache 2.4 deployments, allowing unauthenticated HTTP requests to directly execute the uploaded PHP payload.
