Security Bulletin

This security bulletin contains information about 6 vulnerabilities.

1) Improper input validation

EUVDB-ID: #VU94569

Risk: Medium

CVSSv4.0: 4.6 [CVSS:4.0/AV:N/AC:L/AT:N/PR:H/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2024-21125

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote privileged user to perform a denial of service (DoS) attack.

The vulnerability exists due to improper input validation within the Server: FTS component in MySQL Server. A remote privileged user can exploit this vulnerability to perform a denial of service (DoS) attack.

Mitigation

Install update from vendor's website.

Vulnerable software versions

MySQL Cluster: 7.5.0 - 8.4.0

CPE2.3

2) Inadequate encryption strength

EUVDB-ID: #VU84537

Risk: Low

CVSSv4.0: 2.9 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear]

CVE-ID: CVE-2023-48795

CWE-ID: CWE-326 - Inadequate Encryption Strength

Exploit availability: Yes

Description

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.

Mitigation

Install update from vendor's website.

Vulnerable software versions

MySQL Cluster: 8.0.16 - 8.4.0
