OpenSSL up to 0.9.8 Random Number Generator 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.

Summaryinfo

A vulnerability marked as problematic has been reported in OpenSSL up to 0.9.8. This affects an unknown part of the component Random Number Generator. This manipulation causes cryptographic issue. The identification of this vulnerability is CVE-2008-0166. Furthermore, there is an exploit available. It is suggested to upgrade the affected component.

Detailsinfo

A vulnerability classified as critical was found in OpenSSL up to 0.9.8 (Network Encryption Software). Affected by this vulnerability is an unknown code of the component Random Number Generator. 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. The summary by CVE is:

OpenSSL 0.9.8c-1 up to versions before 0.9.8g-9 on Debian-based operating systems uses a random number generator that generates predictable numbers, which makes it easier for remote attackers to conduct brute force guessing attacks against cryptographic keys.

The bug was discovered 05/13/2008. The weakness was shared 05/13/2008 (Website). It is possible to read the advisory at us-cert.gov. This vulnerability is known as CVE-2008-0166 since 01/09/2008. The exploitation appears to be easy. The attack can be launched remotely. The exploitation doesn't need any form of authentication. Technical details are unknown but a public exploit is available. The attack technique deployed by this issue is T1600 according to MITRE ATT&CK.

A public exploit has been developed in Ruby. It is possible to download the exploit at securityfocus.com. It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 32305 (Debian DSA-1571-1 : openssl - predictable random number generator), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Debian Local Security Checks and running in the context l. The commercial vulnerability scanner Qualys is able to test this issue with plugin 42007 (Debian OpenSSL Package Random Number Generator Weakness).

Upgrading to version 0.9.8g-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 (42375), Exploit-DB (5622), Tenable (32305), SecurityFocus (BID 29179†) and OSVDB (45029†). The entry VDB-42430 is related to this item. Be aware that VulDB is the high quality source for vulnerability data.
