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.

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.

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.

An issue in Nagios XI 2024R1.01 allows a remote attacker to escalate privileges via a crafted script to the /usr/local/nagios/bin/npcd component.

Nagios XI before version 5.11.3 was discovered to contain a SQL injection vulnerability via the bulk modification tool.

A SQL injection vulnerability in Nagios XI 5.11.1 and below allows authenticated attackers with privileges to manage host escalations in the Core Configuration Manager to execute arbitrary SQL commands via the host escalation notification settings.

A SQL injection vulnerability in Nagios XI v5.11.1 and below allows authenticated attackers with announcement banner configuration privileges to execute arbitrary SQL commands via the ID parameter sent to the update_banner_message() function.

A Cross-site scripting (XSS) vulnerability in Nagios XI version 5.11.1 and below allows authenticated attackers with access to the custom logo component to inject arbitrary javascript or HTML via the alt-text field. This affects all pages containing the navbar including the login page which means the attacker is able to to steal plaintext credentials.
