CVE-2016-10174

CRITICAL KEV

NETGEAR Multiple Routers - Unauthenticated Remote Code Execution via Hidden Lang AVI Parameter Buffer Overflow

Title source: llm
STIX 2.1

Exploitation Summary

CVE-2016-10174 is actively exploited and listed in the CISA Known Exploited Vulnerabilities (KEV) catalog, added March 25, 2022. EIP tracks 3 public exploits from researchers including Pedro Ribeiro, Pedro Ribeiro <[email protected]>, including a Metasploit module exploits/linux/http/netgear_wnr2000_rce.

AI-analyzed exploit summary This Metasploit module exploits a buffer overflow in NETGEAR WNR2000v5 routers via the `hidden_lang_avi` parameter, allowing unauthenticated or authenticated RCE. It brute-forces a timestamp token if unauthenticated, then triggers a stack overflow to execute a payload enabling a telnet shell.

Description

The NETGEAR WNR2000v5 router contains a buffer overflow in the hidden_lang_avi parameter when invoking the URL /apply.cgi?/lang_check.html. This buffer overflow can be exploited by an unauthenticated attacker to achieve remote code execution.
