Apache WSS4J: Unauthenticated denial of service via integer overflow in DER parsing of X.509 certificate extensions
An integer overflow in WSS4J's DER bounds check lets an oversized allocation pass validation. An unauthenticated attacker can send a SOAP message carrying an X.509 certificate whose SubjectKeyIdentifier extension declares a length of 0x7FFFFFFF; WSS4J decodes…

Apache WSS4J: UsernameToken replay protection bypassed by re-encoding the Nonce
Apache WSS4J remembers the Nonce of each UsernameToken it accepts, so a captured token cannot be reused. It stored the Nonce as raw base64 text, but authentication decodes that text and uses the bytes.The same bytes can be written as base64 in several ways. A…

Apache WSS4J: WS-SecurityPolicy signature checks skipped in the streaming code after an STR-Transform reference
In the WSS4J streaming (StAX) code, a signature reference using the WS-Security STR-Transform leaves an internal "inside signed content" flag permanently set. The WS-SecurityPolicy enforcer uses that flag to decide whether an element needs checking, so it sto…

Apache WSS4J: WSS4J EncryptedHeader child confusion causing wrong protected-header selection
WSS4J EncryptedHeader child confusion could promote an attacker-controlled plaintext element as the decrypted header, leading to incorrect confidentiality coverage and possible policy bypass. Users are recommended to upgrade to versions 4.0.2 or 3.0.6 or 2.4.…

Apache WSS4J: SAML Sender-Vouches Authentication Bypass
An authentication bypass in the DOM security processor in Apache WSS4J allows unauthenticated remote attackers to forge authenticated SOAP messages via a crafted unsigned SAML sender-vouches assertion containing an attacker-controlled key. Users are recommend…

Critical 9.1
Apache WSS4J: Streaming WS-SecurityPolicy validation may skip element-protection checks.
In the StAX streaming WS-SecurityPolicy validator, certain relative or unsupported XPath expressions can be converted into paths that never match the actual XML element path. A remote SOAP peer may therefore send a required element without the expected signat…

Apache WSS4J: Insufficient Validation of Derived-Key Parameters
Apache WSS4J accepted attacker-controlled derived-key lengths and offsets without adequate bounds. This could permit cryptographically weak keys or excessive CPU and memory consumption when processing crafted WS-Security messages. The fixes enforce a minimum …
