Published Oct 22, 2021 · Updated Aug 4, 2024

Reflected XSS in DedeCMS 7.5 SP2 allows remote attackers to execute script in a victim's browser through crafted homepage parameters. The makehtml_homepage.php handler returns attacker-controlled GET parameter content without adequate sanitization or output encoding. Exploitation requires a victim to open the crafted request, after which the script runs in the DedeCMS origin and can hijack a session or alter displayed content.
