Summary

CVE-2016-10174 is a critical-severity Classic Buffer Overflow (CWE-120) vulnerability in Netgear D6100 Firmware. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploitation for Privilege Escalation (T1068); ranked in the top 0.3% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

The NETGEAR WNR2000v5 router is affected by CVE-2016-10174, a buffer overflow vulnerability (CWE-120) in the hidden_lang_avi parameter that is triggered when the URL /apply.cgi?/lang_check.html is invoked. The flaw carries a CVSS 3.1 score of 9.8.

An unauthenticated attacker with network access can supply a crafted value to the parameter and trigger the overflow, resulting in remote code execution with full impact on confidentiality, integrity, and availability.

Public references include a NETGEAR knowledge-base article addressing insecure remote access and command execution, a full-disclosure mailing-list post, a SecurityFocus entry, a detailed proof-of-concept write-up, and an Exploit-DB entry containing working exploit code.

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.

addresses: CWE-120

Platform-independent managed code eliminates the need for unchecked native buffer copies that are the root cause of classic buffer overflows.

PR.PS-06 mostly match
prevents

Secure development practices directly enforce bounds checking and input validation that prevent classic buffer overflows.

ID.RA-01 partial match
prevents

Vulnerability identification processes such as code review or scanning detect classic buffer overflows before exploitation.

PR.PS-02 partial match
prevents

Routine patching replaces vulnerable code containing unchecked buffer copies with corrected versions.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.

prevents

Secure coding directly requires bounds-checked memory operations, addressing the root cause of CWE-120.

finds

Security testing in development and acceptance can detect buffer overflows through fuzzing and static analysis, though it does not prevent them at the source.

prevents

Secure development life cycle mandates processes that can include input validation and bounds checking to prevent buffer overflows.

prevents

Application security requirements can specify input-size validation and safe buffer handling to mitigate classic buffer overflows.

prevents

Secure system architecture and engineering principles promote defensive coding patterns that reduce the likelihood of unchecked buffer copies.
