Victim-context script execution via unfiltered POST data
Published Aug 30, 2021 · Updated Aug 4, 2024
Reflected XSS in Indexhibit 2.1.5 allows remote attackers to execute arbitrary script in a victim's browser via /plugin/ajax.php. The endpoint reflects attacker-controlled z POST parameters in its response without filtering, causing injected HTML event handlers to execute as page content. Exploitation requires victim interaction with the crafted response and can expose cookies or perform actions in the victim's site context.
