| Title | maccms maccms10 10 Logical Vulnerability / Auth Bypass |
|---|
| Description | A logical vulnerability in the installation module of maccms10 allows unauthenticated remote attackers to bypass the installation lock. The step5() function in application/install/controller/Index.php fails to check for the existence of the install.lock file before execution. By sending a crafted POST request to /admin.php?s=install/index/index&step=5, an attacker can re-initialize the system, overwrite configurations, and create a new administrative account.
