Directory traversal vulnerability in WonderCMS 2.6.0 and earlier allows remote attackers to delete arbitrary files via unspecified vectors.

An issue was discovered in WonderCMS before 2.5.2. An attacker can create a new session on a web application and record the associated session identifier. The attacker then causes the victim to authenticate against the server using the same session identifier. The attacker can access the user's account through the active session. The Session Fixation attack fixes a session on the victim's browser, so the attack starts before the user logs in.

In index.php in WonderCMS before 2.4.1, remote attackers can delete arbitrary files via directory traversal.
