Authenticated browser script execution via raw preference concatenation
Published Feb 25, 2025 · Updated Feb 25, 2025
Stored XSS in Combodo iTop before 2.7.12, 3.1.2, and 3.2.0 allows remote authenticated users to execute browser script. GetListPageSizeFieldBlock concatenates the stored default_page_size preference directly into raw HTML instead of constraining it to an integer. Exploitation requires a user to store the payload through set_pref and open that user's preferences page, exposing data accessible to the same browser session.
