SB20240718169 - Multiple vulnerabilities in MySQL Cluster

Description

This security bulletin contains information about 6 secuirty vulnerabilities.

1) Improper input validation (CVE-ID: CVE-2024-21125)

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.

2) 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.

3) Improper input validation (CVE-ID: CVE-2024-21177)

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

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

4) Use-after-free (CVE-ID: CVE-2024-25062)

The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to a use-after-free error in xmlValidatePopElement when using the XML Reader interface with DTD validation and XInclude expansion enabled. A remote attacker can pass a specially crafted XML document to the application, trigger a use-after-free error and execute arbitrary code on the system.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.

5) Resource exhaustion (CVE-ID: CVE-2023-52425)

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

The vulnerability exists due to application does not properly control consumption of internal resources when parsing large tokens. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.

6) Insufficient verification of data authenticity (CVE-ID: CVE-2023-37920)

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exist due to software recognizes "e-Tugra" root certificates, which were subject to an investigation prompted by reporting of security issues in their systems. An attacker with ability to generate certificates signed with the  compromised "e-Tugra" root certificate can perform MitM attack.
