What is CVE-2021-35479?

Nagios Log Server versions prior to 2.1.9 are susceptible to a Stored Cross-Site Scripting (XSS) vulnerability. This issue arises from improper handling of the custom column view in the alert history and audit log features. When a user interacts with a crafted link or a malicious third-party web page, it can trigger the injection of malicious scripts. Attackers can exploit this vulnerability to execute scripts in the context of the user's session, potentially allowing them to steal sensitive information or perform unauthorized actions. Users and administrators are advised to upgrade to the latest version to mitigate this risk.
