JWT is a library to work with JSON Web Token and JSON Web Signature. Prior to versions 3.4.6, 4.0.4, and 4.1.5, users of HMAC-based algorithms HS256, HS384, and HS512 combined with Lcobucci\JWT\Signer\Key\LocalFileReference as key are having their tokens issued/validated using the file path as...

CVE-2021-41106

The CVE-2021-41106 issue affects the LCobucci JWT library. Before versions 3.4.6, 4.0.4, and 4.1.5, when using HMAC-based algorithms (HS256/384/512) with LocalFileReference as the key, tokens were issued/validated using the file path instead of the file contents. This effectively means the key ma...

CVE-2021-41106: File reference keys leads to incorrect hashes on HMAC algorithms

Description Impact Users of HMAC-based algorithms HS256, HS384, and HS512 combined with Lcobucci\JWT\Signer\Key\LocalFileReference as key are having their tokens issued/validated using the file path as hashing key - instead of the contents. The HMAC hashing functions take any string as input and,...

SSH SHA-1 HMAC Algorithms Enabled

The remote SSH server is configured to enable SHA-1 HMAC algorithms. Although NIST has formally deprecated use of SHA-1 for digital signatures, SHA-1 is still considered secure for HMAC as the security of HMAC does not rely on the underlying hash function being resistant to collisions. Note that...

Security Bulletin: Vulnerability in GnuTLS affects Power Hardware Management Console ( CVE-2018-10845 CVE-2018-10844)

Summary It was found that GnuTLS's implementation of HMAC-SHA-384 and HMAC-SHA-256 was vulnerable to a Lucky Thirteen-style attack. A remote attacker could use this flaw to conduct distinguishing attacks and plain text recovery attacks via statistical analysis of timing data using crafted packets...

Algorithms compute incorrect results in blake2

An issue was discovered in the blake2 crate before 0.8.1 for Rust. The BLAKE2b and BLAKE2s algorithms, when used with HMAC, produce incorrect results because the block sizes are half of the required sizes...

Apache Tapestry HMAC secret key leak

This exploit finds the HMAC secret key used in Java serialization by Apache Tapestry. This key is located in the file AppModule.class by default and looks like the standard representation of UUID in hex digits hd : 6hd-4hd-4hd-4hd-12hd If the HMAC key has been changed to look differently, this...

Form validation can be skipped

Impact By crafting a special GET request containing a valid form state, a form can be submitted without invoking any validators. We consider the severity low because it is not possible to change any form values since the form state is secured with an HMAC that is still verified. That means that...
