openITCOCKPIT is an open source monitoring tool built for different monitoring engines like Nagios, Naemon and Prometheus. openITCOCKPIT Community Edition 5.3.1 and earlier contains an unsafe PHP deserialization pattern in the processing of changelog entries. Serialized changelog data derived from attacker-influenced application state is unserialized without restricting allowed classes. Although no current application endpoint was found to introduce PHP objects into this data path, the presence of an unrestricted unserialize() call constitutes a latent PHP object injection vulnerability. If future code changes, plugins, or refactors introduce object values into this path, the vulnerability could become immediately exploitable with severe impact, including potential remote code execution.

openITCOCKPIT is an open source monitoring tool built for different monitoring engines like Nagios, Naemon and Prometheus. Versions 5.3.1 and below contain an unsafe deserialization sink in the Gearman worker implementation. The worker function registered as oitc_gearman calls PHP's unserialize() on job payloads without enforcing class restrictions or validating data origin. While the intended deployment assumes only trusted internal components enqueue Gearman jobs, this trust boundary is not enforced in application code. In environments where the Gearman service or worker is exposed to untrusted systems, an attacker may submit crafted serialized payloads to trigger PHP Object Injection in the worker process. This vulnerability is exploitable when Gearman listens on non-local interfaces, network access to TCP/4730 is unrestricted, or untrusted systems can enqueue jobs. Default, correctly hardened deployments may not be immediately exploitable, but the unsafe sink remains present in code regardless of deployment configuration. Enforcing this trust boundary in code would significantly reduce risk and prevent exploitation in misconfigured environments. This issue has been fixed in version 5.4.0.

Lilac-Reloaded for Nagios 2.0.8 contains a remote code execution vulnerability in the autodiscovery feature that allows attackers to inject arbitrary commands. Attackers can exploit the lack of input filtering in the nmap_binary parameter to execute a reverse shell by sending a crafted POST request to the autodiscovery endpoint.

Nagios XI versions prior to 2026R1.1 are vulnerable to local privilege escalation due to an unsafe interaction between sudo permissions and application file permissions. A user‑accessible maintenance script may be executed as root via sudo and includes an application file that is writable by a lower‑privileged user. A local attacker with access to the application account can modify this file to introduce malicious code, which is then executed with elevated privileges when the script is run. Successful exploitation results in arbitrary code execution as the root user.

Nagios Log Server versions prior to 2026R1.0.1 are vulnerable to local privilege escalation due to a combination of sudo misconfiguration and group-writable application directories. The 'www-data' user is a member of the 'nagios' group, which has write access to '/usr/local/nagioslogserver/scripts', while several scripts in this directory are owned by root and may be executed via sudo without a password. A local attacker running as 'www-data' can move one of these root-owned scripts to a backup name and create a replacement script with attacker-controlled content at the original path, then invoke it with sudo. This allows arbitrary commands to be executed with root privileges, providing full compromise of the underlying operating system.

nagios

Nagios Log Server versions prior to 2026R1.0.1 contain an authenticated command injection vulnerability in the experimental 'Natural Language Queries' feature. When this feature is configured, certain user-controlled settings—including model selection and connection parameters—are read from the global configuration and concatenated into a shell command that is executed via shell_exec() without proper input handling or command-line argument sanitation. An authenticated user with access to the 'Global Settings' page can supply crafted values in these fields to inject additional shell commands, resulting in arbitrary command execution as the 'www-data' user and compromise of the Log Server host.

Nagios XI versions prior to 2024R1.1.3, under certain circumstances, disclose sensitive user account information (including API keys and hashed passwords) to authenticated users who should not have access to that data. Exposure of API keys or password hashes could lead to account compromise, abuse of API privileges, or offline cracking attempts. CVE-2024-13995 addresses a similar vulnerability with a potentially incomplete fix for the underlying problem in earlier versions.

nagios

Nagios XI versions prior to 2024R1.1.3 contain a privilege escalation vulnerability in which an authenticated administrator could leverage the Migrate Server feature to obtain root privileges on the underlying XI host. By abusing the migration workflow, an admin-level attacker could execute actions outside the intended security scope of the application, resulting in full control of the operating system.

Nagios XI versions prior to 5.8.7 using embedded Nagios Core are vulnerable to cross-site scripting (XSS) via the Core UI’s Views URL handling (escape_string()). Insufficient validation or escaping of user-supplied input may allow an attacker to inject and execute arbitrary script in the context of a victim's browser.

nagios

Nagios XI versions prior to < 2024R1.1 is vulnerable to a cross-site scripting (XSS) when a user visits the "missing page" (404) page after following a link from another website. The vulnerable component, page-missing.php, fails to properly validate or escape user-supplied input, allowing an attacker to craft a malicious link that, when visited by a victim, executes arbitrary JavaScript in the victim’s browser within the Nagios XI domain.

nagios

Nagios Log Server versions prior to 2024R1.3.2 contain a privilege escalation vulnerability in the account email-change workflow. A user could set their own email to an invalid value and, due to insufficient validation and authorization checks tied to email identity state, trigger inconsistent account state that granted elevated privileges or bypassed intended access controls.

nagios

Nagios XI versions prior to 2024R2 contain an improperly owned script, process_perfdata.pl, which is executed periodically as the nagios user but owned by www-data. Because the file was writable by www-data, an attacker with web server privileges could modify its contents, leading to arbitrary code execution as the nagios user when the script is next run. This improper ownership and permission configuration enables local privilege escalation.

nagios

Nagios XI versions prior to 2026R1 contain a remote code execution vulnerability in the Core Config Manager (CCM) Run Check command. Insufficient validation/escaping of parameters used to build backend command lines allows an authenticated administrator to inject shell metacharacters that are executed on the server. Successful exploitation results in arbitrary command execution with the privileges of the Nagios XI web application user and can be leveraged to gain control of the underlying host operating system.

nagios

Nagios XI versions prior to 2024R2 contain a command injection vulnerability in the WinRM plugin. Insufficient validation of user-supplied parameters allows an authenticated administrator to inject shell metacharacters that are incorporated into backend command invocations. Successful exploitation enables arbitrary command execution with the privileges of the Nagios XI web application user and can be leveraged to modify configuration, exfiltrate data, disrupt monitoring operations, or execute commands on the underlying host operating system.

nagios

Nagios XI versions prior to 2024R1.4.2 revealed API keys to users who were not authorized for API access when using Neptune themes. An authenticated user without API privileges could view another user's or their own API key value.

Nagios Network Analyzer versions prior to 2024R2.0.1 contain a vulnerability in the LDAP certificate management functionality whereby the certificate removal operation fails to apply adequate input sanitation. An authenticated administrator can trigger command execution on the underlying host in the context of the web application service, resulting in remote code execution with the service's privileges.

nagios

Nagios Network Analyzer versions prior to 2024R1 contain a stored cross-site scripting (XSS) vulnerability in the Source Groups page (percentile calculator menu). An attacker can supply a malicious payload which is stored by the application and later rendered in the context of other users. When a victim views the affected page the injected script executes in the victim's browser context.
