High
Published: Translated: NVD NIST

Summary

An integer overflow in CGI scripts in Nagios 1.x before 1.4.1 and 2.x before 2.3.1 occurs when handling the Content-Length HTTP header. Remote attackers can exploit this to cause a denial of service (crash) and potentially execute arbitrary code.

Risk Assessment

The risk for the organization includes disruption of the Nagios monitoring system and potential server compromise, which could lead to further security breaches.

Recommendation

Immediately upgrade Nagios to version 1.4.1 or later (for 1.x branch) or 2.3.1 or later (for 2.x branch). If upgrading is not possible, restrict access to CGI scripts to trusted IP addresses only.
