Authentication mechanism absence or evasion In xml-crypto
Description
xml-crypto's HMAC-SHA1 signatures can bypass validation via key confusion
Impact
An attacker can inject an HMAC-SHA1 signature that is valid using only knowledge of the RSA public key. This allows bypassing signature validation.
Patches
Version 2.0.0 has the fix.
Workarounds
The recommendation is to upgrade. In case that is not possible remove the 'http://www.w3.org/2000/09/xmldsig#hmac-sha1' entry from SignedXml.SignatureAlgorithms.
Mitigation
Update Impact
Minimal update. May introduce new vulnerabilities or breaking changes.
