randombit.botan is vulnerable to Improper Access Control
67
Medium Risk
This Affects:
randombit.botanTL;DR
Affected versions of this package are vulnerable to a name constraints bypass in DNS name validation due to improper handling of case sensitivity. The implementation performs case-sensitive comparisons of DNS names, including when falling back to the certificate’s Common Name (CN), allowing crafted inputs with differing letter casing to evade constraint checks. This may result in the acceptance of certificates that should be rejected, weakening certificate validation guarantees.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
Background info
randombit.botan is vulnerable to Improper Access Control in versions 0.0.1 - 3.10.0.
