Invisible-island xterm code injection

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, which was classified as very critical, was found in Invisible-island xterm (Windowing System Software) (the affected version unknown). This affects an unknown part of the component xterm. The manipulation with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

CRLF injection vulnerability in xterm allows user-assisted attackers to execute arbitrary commands via LF (aka \n) characters surrounding a command name within a Device Control Request Status String (DECRQSS) escape sequence in a text file, a related issue to CVE-2003-0063 and CVE-2003-0071.

The weakness was released 01/02/2009 by Paul Szabo (Website). The advisory is shared at us-cert.gov. This vulnerability is uniquely identified as CVE-2008-2383. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Neither technical details nor an exploit are publicly available. The price for an exploit might be around USD $0-$5k at the moment (estimation calculated on 08/03/2021). MITRE ATT&CK project uses the attack technique T1059 for this issue.

The vulnerability scanner Nessus provides a plugin with the ID 67791 (Oracle Linux 3 / 4 / 5 : xterm (ELSA-2009-0018)), which helps to determine the existence of the flaw in a target environment.
