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 was found in SGI IRIX up to 6.3 (Operating System) and classified as very critical. Affected by this issue is some unknown processing of the component Library Handler. The manipulation of the argument LD_LIBRARY_PATH as part of a Environment Variable leads to a remote code execution vulnerability. Impacted is confidentiality, integrity, and availability. CVE summarizes:

telnet allows a remote client to specify environment variables including ld_library_path allowing an attacker to bypass the normal system libraries and gain root access.

The issue has been introduced in 03/01/1993. The weakness was disclosed 10/13/1995 by Sam Hartman. This vulnerability is handled as CVE-1999-0073. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. There are known technical details, but no exploit is available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 05/07/2019).

The vulnerability was handled as a non-public zero-day exploit for at least 956 days. During that time the estimated underground price was around $0-$5k.

Upgrading eliminates this vulnerability. Attack attempts may be identified with Snort ID 712. Furthermore it is possible to detect and prevent this kind of attack with TippingPoint and the filter 9756.

The vulnerability is also documented in the vulnerability database at X-Force (67).
