CVE-2024-49003
Use After Free (CWE-416)
Summary
SQL Server Native Client Remote Code Execution Vulnerability. This is a high severity vulnerability with a CVSS v3.1 base score of 8.8. It affects the SQL Server Native Client and allows for remote code execution. The attack vector is network-based, with low attack complexity and no privileges required. However, user interaction is required for successful exploitation.
Impact
If successfully exploited, this vulnerability could allow an attacker to execute arbitrary code remotely on the affected system. The potential impacts are severe, with high confidentiality, integrity, and availability impacts. This means an attacker could potentially: 1. Access, modify, or delete sensitive data stored in the SQL Server. 2. Execute malicious code with the privileges of the compromised SQL Server process. 3. Disrupt normal operations of the SQL Server and dependent applications. 4. Potentially use the compromised system as a stepping stone for further network intrusion.
Exploitation
There is no evidence that a public proof-of-concept exists. There is no evidence of proof of exploitation at the moment.
Patch
A patch is available for this vulnerability. Microsoft has released an official fix as of November 12, 2024. The security team should prioritize applying this patch to all affected systems.
Mitigation
While patching is the most effective mitigation, the security team should also consider the following recommendations: 1. Apply the official patch from Microsoft as soon as possible. 2. Implement network segmentation to limit the exposure of SQL Server instances to untrusted networks. 3. Ensure that SQL Server Native Client is only used on trusted, internal networks when possible. 4. Educate users about the risks of interacting with untrusted content, as user interaction is required for exploitation. 5. Monitor for unusual activities or unauthorized access attempts related to SQL Server Native Client. 6. Keep all SQL Server components and related software up to date with the latest security patches. 7. Implement the principle of least privilege for SQL Server accounts and associated applications. 8. Use intrusion detection/prevention systems (IDS/IPS) to detect and block potential exploitation attempts.
