CVE-2023-0828Network attack vector

Cookie theft via unsanitized syslog content

Published Oct 3, 2023 · Updated Sep 23, 2024

Stored XSS in the syslog section of Pandora FMS 767 and earlier allows remote authenticated users to steal users' cookie values. The syslog view stores attacker-controlled log content and renders it without neutralizing executable browser markup. Low-privileged access is required to plant the content, and a victim must open the affected view before the script can transmit the victim's cookie to an attacker-controlled server.
