Detailsinfo

A vulnerability classified as critical has been found in Netgear D3600, D6000, D6200, D7000, DM200, JR6150, PR2000, R6020, R6050, R6080, R6120, R6220, R6260, R6700v2, R6800, R6900v2, WNR2020 and XR500 (Router Operating System). This affects an unknown function. 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. The summary by CVE is:

Certain NETGEAR devices are affected by a stack-based buffer overflow by an unauthenticated attacker. This affects D3600 before 1.0.0.75, D6000 before 1.0.0.75, D6200 before 1.1.00.32, D7000 before 1.0.1.68, DM200 before 1.0.0.58, JR6150 before 1.0.1.18, PR2000 before 1.0.0.28, R6020 before 1.0.0.38, R6050 before 1.0.1.18, R6080 before 1.0.0.38, R6120 before 1.0.0.46, R6220 before 1.1.0.80, R6260 before 1.1.0.40, R6700v2 before 1.2.0.36, R6800 before 1.2.0.36, R6900v2 before 1.2.0.36, WNR2020 before 1.1.0.62, and XR500 before 2.3.2.32.
