OpenSSL up to 0.9.7c Message Type infinite loop

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 has been found in OpenSSL (Network Encryption Software) and classified as problematic. This vulnerability affects some unknown processing of the component Message Type Handler. The manipulation with an unknown input leads to a infinite loop vulnerability. The CWE definition for the vulnerability is CWE-835. The product contains an iteration or loop with an exit condition that cannot be reached, i.e., an infinite loop. As an impact it is known to affect availability. CVE summarizes:

OpenSSL 0.9.6 before 0.9.6d does not properly handle unknown message types, which allows remote attackers to cause a denial of service (infinite loop), as demonstrated using the Codenomicon TLS Test Tool.

The issue has been introduced in 12/21/2001. The weakness was presented 11/23/2004 (Website). The advisory is available at us-cert.gov. This vulnerability was named CVE-2004-0081. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1499 by the MITRE ATT&CK project.

The vulnerability was handled as a non-public zero-day exploit for at least 1068 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 15302 (Debian DSA-465-1 : openssl - several vulnerabilities), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 38257 (OpenSSL Denial of Service Vulnerabilities).

Upgrading to version 0.9.6d eliminates this vulnerability. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 3464.

The vulnerability is also documented in the databases at X-Force (15509), Tenable (15302), SecurityFocus (BID 9899†) and Vulnerability Center (SBV-4014†). See VDB-567 and VDB-22379 for similar entries. If you want to get best quality of vulnerability data, you may have to visit VulDB.
