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.

A vulnerability has been found in PostgreSQL up to 8.2.10 (Database Software) and classified as critical. Affected by this vulnerability is some unknown functionality. The manipulation with an unknown input leads to a weak encryption vulnerability. The CWE definition for the vulnerability is CWE-310. As an impact it is known to affect integrity, and availability.

The weakness was released 12/14/2009 by Dan Kaminsky (Moxie Marlinspike) (Website). It is possible to read the advisory at postgresql.org. This vulnerability is known as CVE-2009-4034 since 11/20/2009. The attack can be launched remotely. The exploitation doesn’t need any form of authentication. The technical details are unknown and an exploit is not publicly available. The attack technique deployed by this issue is T1600 according to MITRE ATT&CK.

It is declared as proof-of-concept. The vulnerability scanner Nessus provides a plugin with the ID 52689 (SuSE 11 Security Update : PostgreSQL (SAT Patch Number 1766)), which helps to determine the existence of the flaw in a target environment. It is assigned to the family SuSE Local Security Checks. The commercial vulnerability scanner Qualys is able to test this issue with plugin 165248 (SUSE Security Update for Multiple Packages (SUSE-SR:2010:001)).

Upgrading to version 8.2.11 eliminates this vulnerability. A possible mitigation has been published even before and not after the disclosure of the vulnerability.
