Application information disclosure via XPath result differences
Published Jun 13, 2024 · Updated Aug 2, 2024
XPath injection in the blog and RSS functions of Modern Campus Omni CMS 2023.1 allows remote attackers to disclose application information. The functions evaluate attacker-controlled XPath built-ins and return distinguishable true, false, and error results, exposing the XPath engine version. No authentication or user interaction is required, and the demonstrated consequence is limited to application-information disclosure.
