Version Summary:Apache HTTP Server contains a vulnerability that could allow an unauthenticated, remote attacker to affect Apache user sessions on a targeted system. Updates are available.
 

Description
 
A vulnerability in the mod_session_dbd component of Apache HTTP Server versions prior to 2.4.5 could allow an unauthenticated, remote attacker to affect Apache user sessions.

The vulnerability is due to improper handling of Apache user sessions by the affected software. The software fails to respect the dirty flag when saving sessions and fails to ensure the session ID is updated when the session changes. This affects the updatesession SQL statement. An unauthenticated, remote attacker could exploit the vulnerability via unspecified vectors. A successful exploit could allow the attacker to access sensitive information, make unauthorized modifications to the underlying SQL user session database, or affect service availability. This could allow the attacker to launch additional attacks.

The Apache Software Foundation has confirmed the vulnerability in a changelog at the following link: Apache 2.4.6.

The Apache Software Foundation has released software updates at the following link: Apache 2.4.5 or later

Some vulnerability scanners may identify Cisco Unified Computing System (Managed) as affected by this vulnerability; however, Cisco has confirmed that this products are not affected. Cisco has released a security notice to address this issue at the following link: CVE-2013-2249.

To exploit this vulnerability, an attacker may require access to trusted, internal networks to send crafted requests to the affected software. This access requirement could limit the likelihood of a successful exploit.

Administrators are advised to apply the appropriate updates.

Administrators may consider using IP-based access control lists (ACLs) to allow only trusted systems to access the affected systems.
