AI risk analysis

Summary: The flaw allows authentication bypass via LDAP injection, enabling unauthorized access to SSH servers using Apache MINA SSHD versions 1.2.0 to 2.19.0 and 3.0.0-M1 to 3.0.0-M5.
Exploitability: Exploitation is relatively easy if the sshd-ldap component is configured for password or public key authentication. Precondition is the presence of the sshd-ldap component and its misconfiguration.
Blast radius: If exploited, attackers could gain unauthorized access to the SSH server, potentially leading to full system compromise.
Detection: No reliable host or network indicator is derivable from the published description.
Prioritized remediation: Upgrade to Apache MINA SSHD version 2.20.0 or 3.0.0-M6, which fix this issue by properly escaping filter parameters.

NVD description

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.
