CVE-2022-24435Network attack vector

Browser script execution via undisclosed stored input

Published Feb 24, 2022 · Updated Aug 3, 2024

Stored cross-site scripting in Dojin Club MICMNIS phpUploader 1.2 and earlier allows remote attackers to inject script without authentication. The upstream release identifies stored XSS but does not disclose the input field, endpoint, or missing output-encoding operation that stores and renders the script. Execution occurs in the browser of a user who visits the affected site, limiting the demonstrated consequence to attacker-controlled script in that site's context.
