CVE-2024-48998
Heap-based Buffer Overflow (CWE-122)
Summary
SQL Server Native Client Remote Code Execution Vulnerability. This is a high-severity vulnerability with a CVSS 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 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. Gain unauthorized access to sensitive data stored in the SQL Server. 2. Modify or delete critical database information. 3. Disrupt the availability of the SQL Server, affecting business operations. 4. 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. Microsoft has released an official fix for this vulnerability. The patch was added on November 12, 2024.
Mitigation
1. Apply the official patch released by Microsoft as soon as possible. 2. Implement network segmentation to limit exposure of SQL Server instances. 3. Enforce the principle of least privilege for SQL Server access. 4. Educate users about the risks of interacting with untrusted sources, as user interaction is required for exploitation. 5. Monitor SQL Server logs and network traffic for suspicious activities. 6. Keep all SQL Server components and clients up to date with the latest security updates. 7. Consider using additional security measures such as intrusion detection systems (IDS) or web application firewalls (WAF) to help detect and prevent potential attacks.
