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) Open redirect (CVE-ID: CVE-2023-26159)
The vulnerability allows a remote attacker to redirect victims to arbitrary URL.
The vulnerability exists due to improper sanitization of user-supplied data within the url.parse() function. A remote attacker can create a link that leads to a trusted website, however, when clicked, redirects the victim to arbitrary domain.
Successful exploitation of this vulnerability may allow a remote attacker to perform a phishing attack and steal potentially sensitive information.
