CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:HSummary
CVE-2023-38925 is a high-severity Classic Buffer Overflow (CWE-120) vulnerability in Netgear Dc112A Firmware. 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 4% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
Netgear devices including the DC112A running firmware 1.0.0.64, the EX6200 at 1.0.3.94, and the R6300v2 at 1.0.4.8 contain a buffer overflow in the http_passwd parameter processed by password.cgi. The flaw is tracked as CWE-120 and carries a CVSS 3.1 score of 8.8, reflecting network-reachable exploitation that requires only low privileges and no user interaction.
An authenticated attacker can supply an oversized value to the affected parameter and trigger memory corruption, resulting in arbitrary code execution with full control over the device’s confidentiality, integrity, and availability. Because the vulnerable endpoint is reachable over the network, the attack can be launched remotely once valid credentials are obtained.
Public references point to Netgear’s security disclosure page and a technical write-up containing proof-of-concept details. The current EPSS score of 0.2957 matches its recorded peak, indicating sustained but not sharply increasing exploitation interest since disclosure.

Likely Mitigating Controls AI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Platform-independent managed code eliminates the need for unchecked native buffer copies that are the root cause of classic buffer overflows.
Mitigating Controls (NIST CSF 2.0) AI
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 enforce bounds checking and input validation that prevent classic buffer overflows.
Vulnerability identification processes such as code review or scanning detect classic buffer overflows before exploitation.
Routine patching replaces vulnerable code containing unchecked buffer copies with corrected versions.

Secure coding directly requires bounds-checked memory operations, addressing the root cause of CWE-120.
Security testing in development and acceptance can detect buffer overflows through fuzzing and static analysis, though it does not prevent them at the source.
Secure development life cycle mandates processes that can include input validation and bounds checking to prevent buffer overflows.
Application security requirements can specify input-size validation and safe buffer handling to mitigate classic buffer overflows.
Secure system architecture and engineering principles promote defensive coding patterns that reduce the likelihood of unchecked buffer copies.
