What is CVE-2018-25439?

MetInfo CMS versions prior to 6.1.1 suffer from a path traversal vulnerability in the /include/thumb.php file. This flaw permits unauthenticated attackers to access arbitrary files by manipulating the dir parameter in crafted requests. By bypassing the str_replace filter using backslash sequences, attackers can exploit this vulnerability to access sensitive files, such as config_db.php, especially on Windows systems. Initial exploitation was detected by the Shadowserver Foundation on October 14, 2023.

Affected Version(s)

MetInfo 6.0.0 < 6.1.1
