Incomplete blacklist vulnerability in nrpe.c in Nagios Remote Plugin Executor (NRPE) 2.15 and earlier allows remote attackers to execute arbitrary commands via a newline character in the -a option to libexec/check_nrpe. NOTE: this issue is disputed by multiple parties. It has been reported that the vendor allows newlines as "expected behavior." Also, this issue can only occur when the administrator enables the "dont_blame_nrpe" option in nrpe.conf despite the "HIGH security risk" warning within the comments
The IPXPING_COMMAND in contrib/check_ipxping.c in Nagios Plugins 1.4.16 allows local users to gain privileges via a symlink attack on /tmp/ipxping/ipxping.
Stack-based buffer overflow in the cmd_submitf function in cgi/cmd.c in Nagios Core, possibly 4.0.3rc1 and earlier, and Icinga before 1.8.6, 1.9 before 1.9.5, and 1.10 before 1.10.3 allows remote attackers to cause a denial of service (segmentation fault) via a long message to cmd.cgi.
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.
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.
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.
SQL injection vulnerability in functions/prepend_adm.php in Nagios Core Config Manager in Nagios XI before 2012R2.4 allows remote attackers to execute arbitrary SQL commands via the tfPassword parameter to nagiosql/index.php.
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.
Incomplete blacklist vulnerability in nrpc.c in Nagios Remote Plug-In Executor (NRPE) before 2.14 might allow remote attackers to execute arbitrary shell commands via "$()" shell metacharacters, which are processed by bash.
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.
