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.
Fix
Nothing published yet: no patch, vendor advisory or mitigation reference on NVD, no vendor advisory in the News for this CVE, not in CISA's KEV, no fixed package version. BaselineWatch does not guess at one.
