Apache – CVE-2018-17199

Description

Kayran has detected that the Version of Apache HTTP Server being used is vulnerable to Session Fixation (CWE-384).
The Authenticating of a user, or establishing a new user session without invalidating any existing session identifiers. In short, the mod_session_cookie does not respect expiry time.
Also known as CVE-2018-17199.

In the Version of Apache HTTP server being used, mod_session checks the session expiry time before decoding the session itself.
This will lead to ignoring the session expiry time for mod_session_cookie sessions since the expiry time is being loaded in the time that the session is decoded.
That, will allow attackers to steal authenticated sessions from users.

There’s a chance that this vulnerability will allow attackers to modify system files and information.

Recommendation

To fix CVE-2018-17199, upgrade the version of Apache HTTP Server being used to 2.4.38 or higher.
