A stored cross-site scripting (XSS) vulnerability in the NOC component of Nagios XI version up to and including 2024R1 allows low-privileged users to execute malicious HTML or JavaScript code via the audio file upload functionality from the Operation Center section. This allows any authenticated user to execute arbitrary JavaScript code on behalf of other users, including the administrators.

Nagios XI before version 5.11.3 was discovered to contain a remote code execution (RCE) vulnerability via the component command_test.php.

Cross Site Scripting vulnerability in Nagios Log Server v.2024R1.3.1 allows a remote attacker to execute arbitrary code via a payload into the Email field.

nagios: Incorrect file permissions leading to possible privilege escalation

Nagios Core through 4.3.4 initially executes /usr/sbin/nagios as root but supports configuration options in which this file is owned by a non-root account (and similarly can have nagios.cfg owned by a non-root account), which allows local users to gain privileges by leveraging access to this non-root account.

nagios: Configured administrative account with fixed password and no IP restriction as default

The Fedora Nagios package uses "nagiosadmin" as the default password for the "nagiosadmin" administrator account, which makes it easier for remote attackers to obtain access by leveraging knowledge of the credentials.

nagios: Privilege escalation due to incomplete fix for CVE-2016-8641

Nagios 4.3.2 and earlier allows local users to gain root privileges via a hard link attack on the Nagios init script file, related to CVE-2016-8641.

nagios: Incorrect permissions for PID file

Nagios Core before 4.3.3 creates a nagios.lock PID file after dropping privileges to a non-root account, which might allow local users to kill arbitrary processes by leveraging access to this non-root account for nagios.lock modification before a root script executes a "kill `cat /pathname/nagios.lock`" command.

snoopy: incomplete fixes for command execution flaws

The _httpsrequest function in Snoopy allows remote attackers to execute arbitrary commands. NOTE: this issue exists dues to an incomplete fix for CVE-2008-4796.

nagios: Reflected XSS vulnerability and possible phishing vector

Cross-site scripting (XSS) vulnerability in Nagios.

snoopy: incomplete fixes for command execution flaws

Snoopy allows remote attackers to execute arbitrary commands. NOTE: this vulnerability exists due to an incomplete fix for CVE-2014-5008.

nagios-plugins: check_icmp Arbitrary Option File Read

The check_icmp plugin in Nagios Plugins before 2.0.2 allows local users to obtain sensitive information from INI configuration files via the extra-opts flag, a different vulnerability than CVE-2014-4701.

plugins: IPXPING_COMMAND uses fixed location in /tmp

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.

nagios: possible buffer overflows in cmd.cgi

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.

nrpe: remote command execution when command arguments are enabled

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

nagios-plugins: check_dhcp Arbitrary Option File Read

The check_dhcp plugin in Nagios Plugins before 2.0.2 allows local users to obtain sensitive information from INI configuration files via the extra-opts flag, a different vulnerability than CVE-2014-4702.

nagios-plugins: check_dhcp Arbitrary Option File Read

lib/parse_ini.c in Nagios Plugins 2.0.2 allows local users to obtain sensitive information via a symlink attack on the configuration file in the extra-opts flag. NOTE: this vulnerability exists because of an incomplete fix for CVE-2014-4701.

nagios: Command injection via curl in MagpieRSS

MagpieRSS, as used in the front-end component in Nagios Core before 4.2.2 might allow remote attackers to read or write to arbitrary files by spoofing a crafted response from the Nagios RSS feed server. NOTE: this vulnerability exists because of an incomplete fix for CVE-2008-4796.

nagios: Privilege escalation issue

base/logging.c in Nagios Core before 4.2.4 allows local users with access to an account in the nagios group to gain root privileges via a symlink attack on the log file. NOTE: this can be leveraged by remote attackers using CVE-2016-9565.

Nagios: XSS in the network status map CGI

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.

nagios: unauthorized hosts and services displayed in servicegroup view

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.
