Nagios XI 2024R1.2.2 has an Information Disclosure vulnerability, which allows unauthenticated users to access multiple pages displaying the usernames and email addresses of all current users.

A session management flaw in Nagios Network Analyzer 2024R1.0.3 allows an attacker to reuse session tokens even after a user logs out, leading to unauthorized access and account takeover. This occurs due to insufficient session expiration, where session tokens remain valid beyond logout, allowing an attacker to impersonate users and perform actions on their behalf.

DOM-based Cross Site Scripting (XSS vulnerability in 'Tail Event Logs' functionality in Nagios Nagios Cross-Platform Agent (NCPA) before 2.4.0 allows attackers to run arbitrary code via the name element when filtering for a log.

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.

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 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: 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.

nagios: Reflected XSS vulnerability and possible phishing vector

Cross-site scripting (XSS) vulnerability in Nagios.

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.

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.

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-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: 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: 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-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.

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: 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.

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.

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.
