Unauthenticated file disclosure via attacker-controlled upload redirect
Published Aug 26, 2022 · Updated Oct 21, 2025
Information disclosure in ZK Framework 8.6.4.1, 9.0.1.2, 9.5.1.3, 9.6.0.1, and 9.6.1 allows remote attackers to read web-context files. AuUploader accepts an attacker-controlled nextURI in a multipart POST and forwards the request internally to that path instead of a fixed completion page. An unauthenticated request can expose files such as WEB-INF/web.xml, with no reported ability to write data or interrupt service.
