Technical details

A Cross-Site Scripting (XSS) vulnerability exists in the Ajax transaction manager endpoint (tx_afereload_ajax_transactionmanager) of ARD GEC en ligne. The vulnerability is rooted in the improper sanitization and encoding of the 'accountName' field within Ajax responses. An attacker can intercept and modify these responses to include malicious JavaScript, which is subsequently executed by the victim's browser when the data is rendered. This flaw is reachable over the network without authentication and can result in session hijacking or cookie theft. A proof-of-concept has been identified in public repositories.
