CVE-2024-0056
Description
A vulnerability was found in the .NET Framework. This vulnerability exists in the Microsoft.Data.SqlClient and System.Data.SqlClient SQL Data provider where an attackercan perform an AiTM (adversary-in-the-middle) attack between the SQL client and the SQL server. This may allow the attacker to steal authentication credentials intended for the database server, even if the connection is established over an encrypted channel like TLS.
Statement
This flaw allows attackers to execute an adversary-in-the-middle (AiTM) attack, potentially enabling the theft of authentication credentials even when the connection is encrypted with protocols like TLS. This security lapse could lead to unauthorized access to sensitive databases, raising concerns about data breaches and the compromise of confidential information.
Mitigation
Mitigation for this issue is either not available or the currently available options don't meet the Red Hat Product Security criteria comprising ease of use and deployment, applicability to widespread installation base or stability.
Common Vulnerability Scoring System (CVSS) Score Details
Info alert:Important note
CVSS scores for open source components depend on vendor-specific factors (e.g. version or build chain). Therefore, Red Hat's score and impact rating can be different from NVD and other vendors. Red Hat remains the authoritative CVE Naming Authority (CNA) source for its products and services (see Red Hat classifications).
