Operationally, exploitation aligns with the MITRE ATT&CK technique NTDS (T1003.003); 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.
