Severity: critical
CVSS 3.1: 9.1 (critical) CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N
Affected versions:
- Apache MINA SSHD 1.2.0 before 2.20.0
- Apache MINA SSHD 3.0.0-M1 before 3.0.0-M6
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.
