Ethan Galstad Nagios up to 3.0.5 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 problematic, was found in Ethan Galstad Nagios (Log Management Software). This affects some unknown functionality. 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:

Unspecified vulnerability in Nagios before 3.0.6 has unspecified impact and remote attack vectors related to CGI programs, "adaptive external commands," and "writing newlines and submitting service comments."

The weakness was presented 12/04/2008 with Nagios (Website). The advisory is shared at This vulnerability is uniquely identified as CVE-2008-6373 since 03/02/2009. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. It demands that the victim is doing some kind of user interaction. Neither technical details nor an exploit are publicly available. MITRE ATT&CK project uses the attack technique T1059 for this issue.

It is declared as proof-of-concept. We expect the 0-day to have been worth approximately $25k-$100k. The vulnerability scanner Nessus provides a plugin with the ID 39869 (GLSA-200907-15 : Nagios: Execution of arbitrary code), which helps to determine the existence of the flaw in a target environment. It is assigned to the family Gentoo Local Security Checks.

Upgrading to version 3.0.6 eliminates this vulnerability. Applying a patch is able to eliminate this problem. The bugfix is ready for download at The best possible mitigation is suggested to be upgrading to the latest version. A possible mitigation has been published before and not just after the disclosure of the vulnerability.

The vulnerability is also documented in the databases at X-Force (47081), Tenable (39869), SecurityFocus (BID 32611†), OSVDB (50457†) and Secunia (SA32909†).
