CVE-2022-29217

A vulnerability was found in python-jwt. This issue happens when PyJWT supports multiple different JWT signing algorithms. This flaw allows an attacker submitting the JWT token to choose the used signing algorithm, leading to key confusion through non-blocklisted public key formats...

GHSA-FFQJ-6FQR-9H24 Key confusion through non-blocklisted public key formats

Impact What kind of vulnerability is it? Who is impacted? Disclosed by Aapo Oksman Senior Security Specialist, Nixu Corporation. PyJWT supports multiple different JWT signing algorithms. With JWT, an attacker submitting the JWT token can choose the used signing algorithm. The PyJWT library requir...

GHSA-XM5F-HC9R-76F3 PHP JOSE Library by Gree Inc. Uses a Broken or Risky Cryptographic Algorithm

The PHP JOSE Library by Gree Inc. prior to 2.2.1 is vulnerable to key confusion/algorithm substitution in the JWS component resulting in bypassing the signature verification via crafted tokens...

CVE-2022-29217 Key confusion through non-blocklisted public key formats in PyJWT

PyJWT is a Python implementation of RFC 7519. PyJWT supports multiple different JWT signing algorithms. With JWT, an attacker submitting the JWT token can choose the used signing algorithm. The PyJWT library requires that the application chooses what algorithms are supported. The application can...

SimpleSAMLphp Improper Verification of Cryptographic Signature

The XmlSecLibs library as used in the saml2 library in SimpleSAMLphp before 1.15.3 incorrectly verifies signatures on SAML assertions, allowing a remote attacker to construct a crafted SAML assertion on behalf of an Identity Provider that would pass as cryptographically valid, thereby allowing th...

GHSA-R9JW-MWHQ-WP62 PyJWT vulnerable to key confusion attacks

In PyJWT 1.5.0 and below the invalidstrings check in HMACAlgorithm.preparekey does not account for all PEM encoded public keys. Specifically, the PKCS1 PEM encoded format would be allowed because it is prefaced with the string -----BEGIN RSA PUBLIC KEY----- which is not accounted for. This enable...

Validation Bypass

xml-crypto is vulnerable to validation bypass. The vulnerability exists through a possible key confusion by injecting a valid HMAC-SHA1 signature, as both HMAC and the public key digital signature methods key shares the same variable...

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...
