Background ========== Nagios is an open source host, service and network monitoring program. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-analyzer/nagios-core < 3.0.6-r2 >= 3.0.6-r2 Description =========== Multiple vulnerabilities have been reported in Nagios: * Paul reported that statuswml.cgi does not properly sanitize shell metacharacters in the (1) ping and (2) traceroute parameters (CVE-2009-2288). * Nagios does not properly verify whether an authenticated user is authorized to run certain commands (CVE-2008-5027). * Andreas Ericsson reported that Nagios does not perform validity checks to verify HTTP requests, leading to Cross-Site Request Forgery (CVE-2008-5028). * An unspecified vulnerability in Nagios related to CGI programs, "adaptive external commands," and "writing newlines and submitting service comments" has been reported (CVE-2008-6373). Impact ====== A remote authenticated or unauthenticated attacker may exploit these vulnerabilities to execute arbitrary commands or elevate privileges. Workaround ========== There is no known workaround at this time. Resolution ========== All Nagios users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot -v ">=net-analyzer/nagios-core-3.0.6-r2" NOTE: Users of the Nagios 2 branch can update to version 2.12-r1 which contains a patch to fix CVE-2009-2288. However, that branch is not supported upstream or in Gentoo and we are unaware whether the other vulnerabilities affect 2.x installations.
