status.cgi in Nagios 4.0 before 4.0 beta4 and 3.x before 3.5.1 does not properly restrict access to certain users that are a contact for a service, which allows remote authenticated users to obtain sensitive information about hostnames via the servicegroup (1) overview, (2) summary, or (3) grid style in status.cgi. NOTE: this behavior is by design in most 3.x versions, but the upstream vendor “decided to change it for Nagios 4” and 3.5.1. (CVSS:4.0) (Last Update:2014-02-25)

Multiple off-by-one errors in Nagios Core 3.5.1, 4.0.2, and earlier, and Icinga before 1.8.5, 1.9 before 1.9.4, and 1.10 before 1.10.2 allow remote authenticated users to obtain sensitive information from process memory or cause a denial of service (crash) via a long string in the last key value in the variable list to the process_cgivars function in (1) avail.c, (2) cmd.c, (3) config.c, (4) extinfo.c, (5) histogram.c, (6) notifications.c, (7) outages.c, (8) status.c, (9) statusmap.c, (10) summary.c, and (11) trends.c in cgi/, which triggers a heap-based buffer over-read. (CVSS:5.5) (Last Update:2014-03-05)

Off-by-one error in the process_cgivars function in contrib/daemonchk.c in Nagios Core 3.5.1, 4.0.2, and earlier allows remote authenticated users to obtain sensitive information from process memory or cause a denial of service (crash) via a long string in the last key value in the variable list, which triggers a heap-based buffer over-read. (CVSS:6.4) (Last Update:2014-02-21)

rss-newsfeed.php in Nagios Core 3.4.4, 3.5.1, and earlier, when MAGPIE_CACHE_ON is set to 1, allows local users to overwrite arbitrary files via a symlink attack on /tmp/magpie_cache. (CVSS:6.3) (Last Update:2014-03-05)

Multiple stack-based buffer overflows in the get_history function in history.cgi in Nagios Core before 3.4.4, and Icinga 1.6.x before 1.6.2, 1.7.x before 1.7.4, and 1.8.x before 1.8.4, might allow remote attackers to execute arbitrary code via a long (1) host_name variable (host parameter) or (2) svc_description variable. (CVSS:7.5) (Last Update:2013-06-04)

Multiple cross-site scripting (XSS) vulnerabilities in config.c in config.cgi in (1) Nagios 3.2.3 and (2) Icinga before 1.4.1 allow remote attackers to inject arbitrary web script or HTML via the expand parameter, as demonstrated by an (a) command action or a (b) hosts action. (CVSS:4.3) (Last Update:2011-11-21)

Cross-site scripting (XSS) vulnerability in statusmap.c in statusmap.cgi in Nagios 3.2.3 and earlier allows remote attackers to inject arbitrary web script or HTML via the layer parameter. (CVSS:4.3) (Last Update:2011-09-21)

statuswml.cgi in Nagios before 3.1.1 allows remote attackers to execute arbitrary commands via shell metacharacters in the (1) ping or (2) Traceroute parameters. (CVSS:7.5) (Last Update:2010-04-03)

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.” (CVSS:5.0) (Last Update:2009-07-22)

Cross-site request forgery (CSRF) vulnerability in cmd.cgi in (1) Nagios 3.0.5 and (2) op5 Monitor before 4.0.1 allows remote attackers to send commands to the Nagios process, and trigger execution of arbitrary programs by this process, via unspecified HTTP requests. (CVSS:6.8) (Last Update:2009-08-13)
