nrpe: heap-based buffer overflow due to a wrong integer type conversion

Nagios NRPE 3.2.1 has a Heap-Based Buffer Overflow, as demonstrated by interpretation of a small negative number as a large positive number during a bzero call.

nrpe: insufficient filtering and incorrect parsing of the configuration file may lead to command injection

Nagios NRPE 3.2.1 has Insufficient Filtering because, for example, nasty_metachars interprets \n as the character \ and the character n (not as the \n newline sequence). This can cause command injection.

Improper preservation of permissions in Nagios XI 5.7.4 allows a local, low-privileged, authenticated user to weaken the permissions of files, resulting in low-privileged users being able to write to and execute arbitrary PHP code with root privileges.

Improper neutralization of argument delimiters in a command in Nagios XI 5.7.3 allows a remote, authenticated admin user to write to arbitrary files and ultimately execute code with the privileges of the apache user.

Improper neutralization of special elements used in an OS command in Nagios XI 5.7.3 allows a remote, authenticated admin user to execute operating system commands with the privileges of the apache user.

Cross-site request forgery in Nagios XI 5.7.3 allows a remote attacker to perform sensitive application actions by tricking legitimate users into clicking a crafted link.

An issue was discovered in the Manage Plugins page in Nagios XI before 5.8.0. Because the line-ending conversion feature is mishandled during a plugin upload, a remote, authenticated admin user can execute operating-system commands.

nagios: site-wide Cross Site Request Forgery

Nagios Core application version 4.2.4 is vulnerable to Site-Wide Cross-Site Request Forgery (CSRF) in many functions, like adding – deleting for hosts or servers.

Incorrect Access Control in Nagios Fusion 4.1.8 and earlier allows low-privileged authenticated users to extract passwords used to manage fused servers via the test_server command in ajaxhelper.php.

Creation of a Temporary Directory with Insecure Permissions in Nagios XI 5.7.5 and earlier allows for Privilege Escalation via creation of symlinks, which are mishandled in getprofile.sh.

Incorrect File Permissions in Nagios Fusion 4.1.8 and earlier allows for Privilege Escalation to root via modification of scripts. Low-privileges users are able to modify files that can be executed by sudo.

Command Injection in Nagios Fusion 4.1.8 and earlier allows for Privilege Escalation to nagios.

Incorrect SSL certificate validation in Nagios Fusion 4.1.8 and earlier allows for Escalation of Privileges or Code Execution as root via vectors related to download of an untrusted update package in upgrade_to_latest.sh.

Incorrect File Permissions in Nagios XI 5.7.5 and earlier and Nagios Fusion 4.1.8 and earlier allows for Privilege Escalation to root. Low-privileged users are able to modify files that are included (aka sourced) by scripts executed by root.

Improper Input Validation in Nagios Fusion 4.1.8 and earlier allows an authenticated attacker to execute remote code via table pagination.

Execution with Unnecessary Privileges in Nagios Fusion 4.1.8 and earlier allows for Privilege Escalation as nagios via installation of a malicious component containing PHP code.

Improper input validation in Nagios Fusion 4.1.8 and earlier allows a remote attacker with control over a fused server to inject arbitrary HTML, aka XSS.

Command Injection in Nagios Fusion 4.1.8 and earlier allows Privilege Escalation from apache to root in cmd_subsys.php.

Command Injection in Nagios Fusion 4.1.8 and earlier allows for Privilege Escalation or Code Execution as root via vectors related to corrupt component installation in cmd_subsys.php.

Insufficient Verification of Data Authenticity in Nagios Fusion 4.1.8 and earlier and Nagios XI 5.7.5 and earlier allows for Escalation of Privileges or Code Execution as root via vectors related to an untrusted update package to upgrade_to_latest.sh.
