Nuclei template for detecting CVE-2026-1107 in EyouCMS, exploiting path traversal in check_userinfo to read arbitrary files and potentially achieve code execution.
Nuclei template for detecting CVE-2026-1107 in EyouCMS.
The vulnerability allows unauthenticated attackers to perform Path Traversal/Arbitrary File Read via the check_userinfo function in Diyajax.php.
Diyajax.php)POST /index.php?m=api&c=Diyajax&a=check_userinfo (Parameter: viewfile)This template uses a High-Fidelity detection method. Instead of guessing configuration files (which may vary by OS or installation), it attempts to read the source code of the root index.php file using the traversal payload ../../index.php.
If the server responds with raw PHP tags (<?php, define('APP_PATH'), the target is confirmed vulnerable.
