CVE-2022-29226 Trivial authentication bypass in Envoy

Envoy is a cloud-native high-performance proxy. In versions prior to 1.22.1 the OAuth filter implementation does not include a mechanism for validating access tokens, so by design when the HMAC signed cookie is missing a full authentication flow should be triggered. However, the current...

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-6MWH-FW4P-75FJ Deserialization of Untrusted Data in Apache Tapestry

By manipulating classpath asset file URLs, an attacker could guess the path to a known file in the classpath and have it downloaded. If the attacker found the file with the value of the tapestry.hmac-passphrase configuration symbol, most probably the webapp's AppModule class, the value of this...

Non-constant time HMAC comparison

Jenkins 2.218 and earlier, LTS 2.204.1 and earlier does not use a constant-time comparison when checking whether two HMACs are equal. This could potentially allow attackers to use statistical methods to obtain a valid HMAC for an attacker-controlled input value. Jenkins 2.219, LTS 2.204.2 now use...

GHSA-7JFM-PX59-99W8 Typo3 Extbase Framework Unsafe Deserialization

The Extbase Framework in TYPO3 4.6.x through 4.6.6, 4.7, and 6.0 unserializes untrusted data, which allows remote attackers to unserialize arbitrary objects and possibly execute arbitrary code via vectors related to "a missing signature HMAC for a request argument."...

TYPO3 Improper Access Control vulnerability

The old Form Content Element component in TYPO3 4.5.0 through 4.5.31, 4.7.0 through 4.7.16, 6.0.0 through 6.0.11, and 6.1.0 through 6.1.6 allows remote authenticated editors to generate arbitrary HMAC signatures and bypass intended access restrictions via unspecified vectors...

TYPO3 allows remote authenticated backend users to unserialize arbitrary objects

viewhelp.php in the backend help system in TYPO3 4.5.x before 4.5.19, 4.6.x before 4.6.12 and 4.7.x before 4.7.4 allows remote authenticated backend users to unserialize arbitrary objects and possibly execute arbitrary PHP code via an unspecified parameter, related to a "missing signature HMAC."...

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...

Nimbus JOSE+JWT missing overflow check

In Nimbus JOSE+JWT before 4.39, there is no integer-overflow check when converting length values from bytes to bits, which allows attackers to conduct HMAC bypass attacks by shifting Additional Authenticated Data AAD and ciphertext so that different plaintext is obtained for the same HMAC...

In Nimbus JOSE+JWT before 4.39, there is no integer-overflow check when converting length values from bytes to bits, which allows attackers to conduct HMAC bypass attacks by shifting Additional Authenticated Data AAD and ciphertext so that different plaintext is obtained for the same HMAC...

Improper Validation of Integrity Check Value in Bouncy Castle

The default BKS keystore use an HMAC that is only 16 bits long, which can allow an attacker to compromise the integrity of a BKS keystore. Bouncy Castle release 1.47 changes the BKS format to a format which uses a 160 bit HMAC instead. This applies to any BKS keystore generated prior to BC 1.47...
