Unverified50% confidenceDecision RuleExact time
Hard rules for handling signed XML include: prohibit multiple parsers from processing the same security-sensitive XML, perform C14N before signature verification and extract identity based on the canonicalized result, strictly validate namespaces, and use absolute paths in XPath.

UnverifiedXML signatures allow signing a subset of a document, and the verifying party must determine which part has been signed.79% similarUnverifiedThe root cause of XML Signature Wrapping attacks lies in the ambiguity between node references under XPath semantics and actual processing paths in XML documents, allowing attackers to inject forged assertion nodes so that signature validation passes while the effective identity is tampered with.78% similarUnverifiedAn attacker can craft a piece of XML so that the signature verifier reads user A's data while the identity extractor reads user B's identity (usually an administrator), thereby bypassing the system while the signature remains valid.70% similarUnverifiedSignature verification must not only check the signature value itself, but must also enforce a locked list of allowed algorithms, rather than trusting the algorithm declared in the token header.64% similarUnverified签名机制是平台防止接口被滥用的常见安全手段，服务器会校验请求签名的合法性63% similar
