Detailsinfo

A vulnerability was found in Cisco ASA 5500 up to 9.1(1) (Firewall Software) and classified as problematic. Affected by this issue is an unknown function of the component ISAKMP Implementation. The manipulation with an unknown input leads to a information disclosure vulnerability. Using CWE to declare the problem leads to CWE-200. The product exposes sensitive information to an actor that is not explicitly authorized to have access to that information. Impacted is confidentiality. CVE summarizes:

The ISAKMP implementation on Cisco Adaptive Security Appliances (ASA) devices generates different responses for IKE aggressive-mode messages depending on whether invalid VPN groups are specified, which allows remote attackers to enumerate groups via a series of messages, aka Bug ID CSCue73708.

The bug was discovered 02/21/2013. The weakness was released 04/17/2013 by Daniel Turner with Trustwave SpiderLabs as TWSL2013-004 as not defined advisory (Website). The advisory is shared for download at trustwave.com. The public release was coordinated with the vendor. This vulnerability is handled as CVE-2013-1194 since 01/11/2013. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. Technical details are unknown but a public exploit is available. The MITRE ATT&CK project declares the attack technique as T1592.

It is declared as proof-of-concept. The vulnerability was handled as a non-public zero-day exploit for at least 55 days. During that time the estimated underground price was around $25k-$100k.

Upgrading to version 9.1(2) eliminates this vulnerability. A possible mitigation has been published immediately after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (83673), SecurityFocus (BID 59295†), OSVDB (92545†) and Vulnerability Center (SBV-39655†). If you want to get best quality of vulnerability data, you may have to visit VulDB.
