CVE-2024-42475
In the OAuth library for nim prior to version 0.11, the `state` values generated by the `generateState` function do not have sufficient entropy. These can be successfully guessed by an attacker allowing them to perform a CSRF vs a user, associating the user's session with the attacker's protected resources. While `state` isn't exactly a cryptographic value, it should be generated in a cryptographically secure way. `generateState` should be using a CSPRNG. Version 0.11 modifies the `generateState` function to generate `state` values of at least 128 bits of entropy while using a CSPRNG.
CVSS
- Versión: 3.1
