CVE-2024-5409Network attack vector

Session data theft via reflected tamper parameter

Published May 27, 2024 · Updated Aug 1, 2024

Reflected XSS in RhinOS 3.0-1190 allows remote attackers to obtain a victim's session details through a crafted URL. The /admin/lib/phpthumb/phpthumb.php endpoint places the tamper parameter into web output without adequate neutralization. Exploitation requires a victim to open the attacker-supplied URL, after which injected script runs in the victim's browser context.
