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, which was classified as problematic, was found in OpenSSL 0.9.8/1.0.0/1.0.1/1.0.2 (Network Encryption Software). This affects an unknown part of the component ECParameters Handler. The manipulation with an unknown input leads to a resource management vulnerability. CWE is classifying the issue as CWE-399. This is going to have an impact on availability.

The issue has been introduced in 07/05/2005. The weakness was published 06/11/2015 by Joseph Birr-Pixton as secadv_20150611.txt as confirmed advisory (Website). It is possible to read the advisory at openssl.org. This vulnerability is uniquely identified as CVE-2015-1788 since 02/16/2015. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. The technical details are unknown and an exploit is not publicly available.

The vulnerability was handled as a non-public zero-day exploit for at least 3628 days. During that time the estimated underground price was around $5k-$25k. The vulnerability scanner Nessus provides a plugin with the ID 84152 (OpenSSL 1.0.0 < 1.0.0s Multiple Vulnerabilities), 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. The commercial vulnerability scanner Qualys is able to test this issue with plugin 316103 (Cisco ASA OpenSSL Multiple Vulnerabilities (cisco-sa-20150612-openssl)).

Upgrading to version 0.9.8zg, 1.0.0s, 1.0.1n or 1.0.2b eliminates this vulnerability. A possible mitigation has been published before and not just after the disclosure of the vulnerability. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 20029.

The vulnerability is also documented in the databases at X-Force (103778), Tenable (84152), SecurityFocus (BID 75154†), SecurityTracker (ID 1032564†) and Vulnerability Center (SBV-56788†).
