CVE-2022-1434

The OpenSSL 3.0 implementation of the RC4-MD5 ciphersuite incorrectly uses the AAD data as the MAC key. This makes the MAC key trivially predictable. An attacker could exploit this issue by performing a man-in-the-middle attack to modify data being sent from one endpoint to an OpenSSL 3.0 recipie...

GHSA-2QP9-WG27-9PCV 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...

OpenSSL Encryption Problem Vulnerability (CNVD-2022-37790)

OpenSSL is an open source general-purpose cryptographic library from the Openssl team capable of implementing the Secure Sockets Layer SSLv2/v3 and Secure Transport Layer TLSv1 protocols. The product supports multiple encryption algorithms, including symmetric ciphers, hashing algorithms, secure...

FreeBSD : OpenSSL -- Multiple vulnerabilities (fceb2b08-cb76-11ec-a06f-d4c9ef517024)

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the fceb2b08-cb76-11ec-a06f-d4c9ef517024 advisory. - The crehash script does not properly sanitise shell metacharacters to prevent command...

CVE-2022-1434

The CVE-2022-1434 issue affects the RC4-MD5 ciphersuite in OpenSSL 3.0, where the AAD data is incorrectly used as the MAC key, allowing an attacker to modify data in transit without decrypting it. The vulnerability requires both endpoints to negotiate RC4-MD5, and it is not exploitable when TLSv1...

CVE-2022-1434 Incorrect MAC key used in the RC4-MD5 ciphersuite

TokenTactics - Azure JWT Token Manipulation Toolset

Azure JSON Web Token "JWT" Manipulation Toolset Azure access tokens allow you to authenticate to certain endpoints as a user who signs in with a device code. Even if they used multi-factor authentication. Once you have a user's access token, it may be possible to access certain apps such as...

CVE-2021-32791

A flaw was found in modauthopenidc. The AES GCM encryption uses a static IV and AAD which could lead to other cryptographic attacks. The highest threat from this liability is to data confidentiality...

AZL-6481 CVE-2021-32791 affecting package httpd for versions less than 2.4.52-1

modauthopenidc is an authentication/authorization module for the Apache 2.x HTTP server that functions as an OpenID Connect Relying Party, authenticating users against an OpenID Connect Provider. In modauthopenidc before version 2.4.9, the AES GCM encryption in modauthopenidc uses a static IV and...

Authentication Bypass

nimbus-jose-jwt is vulnerable to authentication bypass. The bypass exists because the library ignores the checking of integer-overflow when converting length values from bytes to bits. A malicious user can shift Additional Authenticated Data AAD and ciphertext, resulting in a different plaintext...
