Detailsinfo

A vulnerability was found in Netgear D6400, D7000v2, D8500, DGN2200v4, DGND2200Bv4, EX3700, EX3800, EX6000, EX6100, EX6120, EX6130, EX6150v1, EX6200, EX7000, R6250, R6300v2, R6400, R6400v2, R6700, R6900, R7000, R7900, R8000, R8300, R8500, R6900P, R7000P, R7100LG, R7300DST, R7900P, R8000P, WN2500RPv2, WNDR3400v3 and WNR3500Lv2 (Wireless LAN Software). It has been classified as problematic. Affected is an unknown functionality. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as 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). This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Certain NETGEAR devices are affected by a stack-based buffer overflow by an unauthenticated attacker. This affects D6220 before 1.0.0.44, D6400 before 1.0.0.78, D7000v2 before 1.0.0.51, D8500 before 1.0.3.42, DGN2200v4 before 1.0.0.110, DGND2200Bv4 before 1.0.0.110, EX3700 before 1.0.0.70, EX3800 before 1.0.0.70, EX6000 before 1.0.0.30, EX6100 before 1.0.2.24, EX6120 before 1.0.0.40, EX6130 before 1.0.0.22, EX6150v1 before 1.0.0.42, EX6200 before 1.0.3.88, EX7000 before 1.0.0.66, R6250 before 1.0.4.26, R6300v2 before 1.0.4.28, R6400 before 1.0.1.36, R6400v2 before 1.0.2.52, R6700 before 1.0.1.46, R6900 before 1.0.1.46, R7000 before 1.0.9.28, R7900 before 1.0.2.10, R8000 before 1.0.4.12, R8300 before 1.0.2.122, R8500 before 1.0.2.122, R6900P before 1.3.1.64, R7000P before 1.3.1.64, R7100LG before 1.0.0.46, R7300DST before 1.0.0.68, R7900P before 1.3.0.10, R8000P before 1.3.0.10, WN2500RPv2 before 1.0.1.54, WNDR3400v3 before 1.0.1.22, and WNR3500Lv2 before 1.2.0.54.
