Netgear WNR3500Lv2 stack-based overflow

CVSS Meta Temp Score
CVSS is a standardized scoring system to determine possibilities of attacks. The Temp Score considers temporal factors like disclosure, exploit and countermeasures. The unique Meta Score calculates the average score of different sources to provide a normalized scoring system.
Current Exploit Price (≈)
Our analysts are monitoring exploit markets and are in contact with vulnerability brokers. The range indicates the observed or calculated exploit price to be seen on exploit markets. A good indicator to understand the monetary effort required for and the popularity of an attack.
CTI Interest Score
Our Cyber Threat Intelligence team is monitoring different web sites, mailing lists, exploit markets and social media networks. The CTI Interest Score identifies the interest of attackers and the security community for this specific vulnerability in real-time. A high score indicates an elevated risk to be targeted for this vulnerability.

Detailsinfo

A vulnerability was found in Netgear DGN2200v1, D8500, D7000v2, D6400, D6220, JNDR3000, R8000, R8500, R8300, R7900, R7000P, R7300DST, R7100LG, R6900P, R7000, R6900, R6700, R6400v2, R6400, R6300v2, R6250, WNDR3400v3, WNDR4500v2 and WNR3500Lv2 (Wireless LAN Software) and classified as critical. This issue affects an unknown code block. The manipulation with an unknown input leads to a stack-based overflow vulnerability. Using CWE to declare the problem leads to CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Certain NETGEAR devices are affected by a stack-based buffer overflow by an unauthenticated attacker. This affects DGN2200v1 before 1.0.0.58, D8500 before 1.0.3.42, D7000v2 before 1.0.0.51, D6400 before 1.0.0.78, D6220 before 1.0.0.44, JNDR3000 before 1.0.0.24, R8000 before 1.0.4.18, R8500 before 1.0.2.122, R8300 before 1.0.2.122, R7900 before 1.0.2.16, R7000P before 1.3.2.34, R7300DST before 1.0.0.68, R7100LG before 1.0.0.46, R6900P before 1.3.2.34, R7000 before 1.0.9.28, R6900 before 1.0.1.46, R6700 before 1.0.1.46, R6400v2 before 1.0.2.56, R6400 before 1.0.1.42, R6300v2 before 1.0.4.28, R6250 before 1.0.4.26, WNDR3400v3 before 1.0.1.22, WNDR4500v2 before 1.0.0.72, and WNR3500Lv2 before 1.2.0.50.
