Authenticated resource disclosure via unsafe callback XML parsing
Published Feb 12, 2025 · Updated Feb 12, 2025
XXE in CloudWebSoft YWOA 2024.07.03 allows remote authenticated users to read server-accessible resources through crafted callback XML. XMLParse.extract creates a default DocumentBuilderFactory, parses the supplied string without disabling DTDs or external entities, and returns expanded entity text from Encrypt or ToUserName elements. Low-privilege access to the WXCallBack interface is required; entity resolution can disclose resources reachable by the server and trigger server-side requests.
