Description

This security bulletin contains information about 2 secuirty vulnerabilities.


1) Inadequate encryption strength (CVE-ID: CVE-2023-48795)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to incorrect implementation of the SSH Binary Packet Protocol (BPP), which mishandles the handshake phase and the use of sequence numbers. A remote attacker can perform MitM attack and delete the SSH2_MSG_EXT_INFO message sent before authentication starts, allowing the attacker to disable a subset of the keystroke timing obfuscation features introduced in OpenSSH 9.5.

The vulnerability was dubbed "Terrapin attack" and it affects both client and server implementations.


2) LDAP injection (CVE-ID: CVE-2022-46337)

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to improper input validation when processing DLAP queries. A remote non-authenticated attacker can send a specially crafted LDAP query to the application, bypass authentication process and gain unauthorized access to the application.
