Cisco Access Gateway 4.x DNS Cache cryptographic issue

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in Cisco Access Gateway 4.x. It has been declared as critical. This vulnerability affects some unknown processing of the component DNS Cache. The manipulation with an unknown input leads to a cryptographic issue vulnerability. The CWE definition for the vulnerability is CWE-310. As an impact it is known to affect confidentiality, and integrity. CVE summarizes:

The DNS protocol, as implemented in (1) BIND 8 and 9 before 9.5.0-P1, 9.4.2-P1, and 9.3.5-P1; (2) Microsoft DNS in Windows 2000 SP4, XP SP2 and SP3, and Server 2003 SP1 and SP2; and other implementations allow remote attackers to spoof DNS traffic via a birthday attack that uses in-bailiwick referrals to conduct cache poisoning against recursive resolvers, related to insufficient randomness of DNS transaction IDs and source ports, aka "DNS Insufficient Socket Entropy Vulnerability" or "the Kaminsky bug."

The weakness was shared 09/03/2008 by Dan Kaminsky with IOActive (Website). The advisory is available at support.citrix.com. This vulnerability was named CVE-2008-1447 since 03/21/2008. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. Technical details are unknown but a public exploit is available. This vulnerability is assigned to T1600 by the MITRE ATT&CK project.

A public exploit has been developed by Marc Bevand and been published even before and not after the advisory. It is possible to download the exploit at exploit-db.com. It is declared as highly functional. As 0-day the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 72834 (MS08-037: Vulnerabilities in DNS Could Allow Spoofing (951746) (uncredentialed check)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family DNS and running in the context r. The commercial vulnerability scanner Qualys is able to test this issue with plugin 296021 (Oracle Solaris 10 Multiple Vulnerabilities (Third Party Bulletin - January 2018)).

Upgrading eliminates this vulnerability. Applying a patch is able to eliminate this problem. The bugfix is ready for download at support.citrix.com. The best possible mitigation is suggested to be upgrading to the latest version. A possible mitigation has been published even before and not after the disclosure of the vulnerability. Attack attempts may be identified with Snort ID 13949. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 6267.

The vulnerability is also documented in the databases at X-Force (43334), Exploit-DB (6130), Tenable (72834), SecurityFocus (BID 30131†) and OSVDB (52517†). The entries VDB-10328, VDB-10919, VDB-67591 and VDB-68898 are related to this item. Once again VulDB remains the best source for vulnerability data.
