Apache MINA SSHD: LDAP injection in sshd-ldap

Authentication bypass via LDAP injection in component sshd-ldap in Apache MINA SSHD versions 1.2.0 to 2.19.0 and 3.0.0-M1 to 3.0.0-M5.




Apache MINA SSHD is a Java library for client-side and server-side SSH. 
The optional sshd-ldap component provides support for integrating 
password and publickey authentication on the server side with an LDAP 
server.




sshd-ldap is an optional component. SSH servers implemented with Apache 
MINA SSHD are affected only if they use sshd-ldap and do configure it to be used for password of public key authentication.

Other Apache MINA SSHD servers are not affected.




Lack of escaping LDAP filter metacharacters enabled successful authentication with username "*" and password "*".




Users are recommended to upgrade affected applications to version 2.20.0 or 3.0.0-M6, which fix this issue by properly escaping filter parameters according to RFC 4515.

CWE-305 Authentication Bypass by Primary Weakness

The authentication algorithm is sound, but the implemented mechanism can be bypassed as the result of a separate weakness that is primary to the authentication error.

CWE-90 Improper Neutralization of Special Elements used in an LDAP Query ('LDAP Injection')

The product constructs all or part of an LDAP query using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended LDAP query when it is sent to a downstream component.
