CVE-2025-48994 SignXML's signature verification with HMAC is vulnerable to an algorithm confusion attack

SignXML is an implementation of the W3C XML Signature standard in Python. When verifying signatures with X509 certificate validation turned off and HMAC shared secret set signxml.XMLVerifier.verifyrequirex509=False, hmackey=..., versions of SignXML prior to 4.0.4 are vulnerable to a potential...

Important: perl-Mojolicious

Issue Overview: Mojolicious versions from 0.999922 through 9.39 for Perl uses a hard coded string, or the application's class name, as a HMAC session secret by default. These predictable default secrets can be exploited to forge session cookies. An attacker who knows or guesses the secret could...

CVE-2024-25714

In Rhonabwy through 1.1.13, HMAC signature verification uses a strcmp function that is vulnerable to side-channel attacks, because it stops the comparison when the first difference is spotted in the two signatures. The fix uses gnutlsmemcmp, which has constant-time execution...

CVE-2024-47943

The firmware upgrade function in the admin web interface of the Rittal IoT Interface & CMC III Processing Unit devices checks if the patch files are signed before executing the containing run.sh script. The signing process is kind of an HMAC with a long string as key which is hard-coded in the...

CVE-2024-34358

TYPO3 is an enterprise content management system. Starting in version 9.0.0 and prior to versions 9.5.48 ELTS, 10.4.45 ELTS, 11.5.37 LTS, 12.4.15 LTS, and 13.1.1, the ShowImageController eID txcmsshowpic lacks a cryptographic HMAC-signature on the frame HTTP query parameter e.g...

CVE-2023-23928

reason-jose is a JOSE implementation in ReasonML and OCaml.Jose.Jws.validate does not check HS256 signatures. This allows tampering of JWS header and payload data if the service does not perform additional checks. Such tampering could expose applications using reason-jose to authorization bypass...

CVE-2023-46943

An issue was discovered in NPM's package @evershop/evershop before version 1.0.0-rc.8. The HMAC secret used for generating tokens is hardcoded as "secret". A weak HMAC secret poses a risk because attackers can use the predictable secret to create valid JSON Web Tokens JWTs, allowing them access t...

CVE-2023-47640
