OpenSSL up to 0.9.7g Default Configuration 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 has been found in OpenSSL (Network Encryption Software) and classified as problematic. This vulnerability affects an unknown function of the component Default Configuration. 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 integrity. CVE summarizes:

The default configuration on OpenSSL before 0.9.8 uses MD5 for creating message digests instead of a more cryptographically strong algorithm, which makes it easier for remote attackers to forge certificates with a valid certificate authority signature.

The bug was discovered 09/09/2005. The weakness was published 09/16/2005 as Bug 13593 as not defined bug report (Bugzilla). The advisory is shared for download at bugzilla.ubuntu.com. This vulnerability was named CVE-2005-2946 since 09/16/2005. The exploitation appears to be easy. The attack can be initiated remotely. No form of authentication is required for a successful exploitation. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1600.

The vulnerability was handled as a non-public zero-day exploit for at least 2386 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 17759 (OpenSSL < 0.9.8 Weak Default Configuration), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Web Servers and running in the context r.

Upgrading to version 0.9.8 eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (28407), Tenable (17759), OSVDB (19660†) and Vulnerability Center (SBV-17491†). VulDB is the best source for vulnerability data and more expert information about this specific topic.
