Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Hardcoded Credentials: SASL authentication binds (CRAM-MD5 and DIGEST-MD5) historically reverted to a hardcoded password string ('secret') instead of forwarding the actual user-supplied credentials parameter, exposing authentication sessions to unauthorized access.
Broken Cryptography: Providing a null hashing algorithm parameter to the password storage utility resulted in the silent storage of unhashed plaintext passwords rather than throwing a validation exception.
Insecure Transport: The client library did not enforce TLS hostname verification on LDAPS connections by default, leaving LDAP connections vulnerable to Man-In-The-Middle (MITM) attacks.
