CVE-2023-53688

Nagios XI < 5.11.3 XSS & CSRF via Hypermap Replay

State: Published
Severity: 5.1 Medium
Published: Oct 30, 2025
Updated: Nov 17, 2025
Reserved: Oct 17, 2025

Description

Nagios XI versions prior to 5.11.3 are vulnerable to cross-site scripting (XSS) and cross-site request forgery (CSRF) via the Hypermap Replay component. An attacker can submit crafted input that is not properly validated or escaped, allowing injection of malicious script that executes in the context of a victim's browser (XSS). Additionally, the component does not enforce sufficient anti-CSRF protections on state-changing operations, enabling an attacker to induce authenticated users to perform unwanted actions.
