FKIE_CVE-2018-17199
Vulnerability from fkie_nvd - Published: 2019-01-30 22:29 - Updated: 2026-06-17 01:45
Severity
Summary
In Apache HTTP Server 2.4 release 2.4.37 and prior, mod_session checks the session expiry time before decoding the session. This causes session expiry time to be ignored for mod_session_cookie sessions since the expiry time is loaded when the session is decoded.
