CVE-2009-4269 Information

Description

The password hash generation algorithm in the BUILTIN authentication functionality for Apache Derby before 10.6.1.0 performs a transformation that reduces the size of the set of inputs to SHA-1 which produces a small search space that makes it easier for local and possibly remote attackers to crack passwords by generating hash collisions related to password substitution.
