CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:HSummary
CVE-2024-49013 is a high-severity Heap-based Buffer Overflow (CWE-122) vulnerability in Microsoft Sql Server 2016. Its CVSS base score is 8.8 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 31% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2024-49013 is a remote code execution vulnerability in the SQL Server Native Client component. It carries a CVSS 3.1 base score of 8.8 with an attack vector of network, low attack complexity, no required privileges, and required user interaction, resulting in high impact to confidentiality, integrity, and availability. The weakness is tracked under CWE-122.
An unauthenticated remote attacker can exploit the flaw by convincing a user to interact with specially crafted content, such as opening a malicious file or visiting a web page that triggers the vulnerable client code. Successful exploitation grants the attacker the ability to execute arbitrary code in the context of the affected process.
Microsoft's advisory at https://msrc.microsoft.com/update-guide/vulnerability/CVE-2024-49013 provides official guidance on available patches and mitigations. The EPSS score rose from a low baseline to a peak of 0.0703 on 2025-12-11 before receding to the current value of 0.0403, indicating that exploitation interest increased after disclosure.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation (including fuzzing and memory-error detectors) can discover heap overflows after they have been coded.
Input validation enforces bounds checking on data written to heap buffers, directly stopping the overflow condition from being introduced.
Security engineering principles require use of memory-safe constructs and bounds-checked allocation routines that avoid introducing heap overflows.
Memory-protection mechanisms limit the ability of a heap overflow to execute attacker-controlled code or corrupt adjacent structures.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Secure-development practices directly require bounds checking and safe memory handling that prevent heap overflows.
Vulnerability scanning and recording can discover heap-overflow flaws but does not prevent their introduction in code.
Timely patching removes known heap-overflow instances after they exist.

Security testing in development and acceptance can detect heap overflows before release.
Secure development lifecycle mandates practices that reduce the likelihood of introducing heap overflows.
Application security requirements can specify bounds-checking and safe memory APIs that mitigate heap overflows.
Secure architecture and engineering principles include memory-safety and input-validation controls that address heap overflows.
Secure coding standards directly prescribe techniques (safe functions, bounds checks) that prevent heap-based buffer overflows.
Change management ensures controlled deployment of fixes for discovered heap-overflow vulnerabilities.
