CVE-2024-34923Network attack vector

Browser script execution via reflected HTML input

Published May 27, 2024 · Updated Feb 13, 2025

Reflected XSS in affected Avocent DSR2030 and SVIP1020 firmware allows remote attackers to execute script through crafted links. The web interface returns attacker-supplied HTML or JavaScript to the victim's browser without sufficient neutralization; the public disclosure identifies no endpoint or parameter. DSR2030 03.04.00.07 and SVIP1020 01.06.00.03 are the tested vulnerable releases; a victim must follow the link, enabling content changes, redirects, or credential theft in that browser context.
