TITLE

D-Link DIR-850L Vulnerability related to certificate validation in device firmware

Trust: 0.8

sources: JVNDB: JVNDB-2017-008139

DESCRIPTION

The D-Link NPAPI extension, as used on D-Link DIR-850L REV. A (with firmware through FW114WWb07_h2ab_beta1) and REV. B (with firmware through FW208WWb02) devices, does not verify X.509 certificates from SSL servers, which allows man-in-the-middle attackers to spoof servers and obtain sensitive information via a crafted certificate. D-Link DIR-850L There is a certificate validation vulnerability in the device firmware.Information may be obtained. D-LinkDIR-850LREV.A and REV.B are both D-Link wireless router products. A security vulnerability exists in the D-LinkDIR-850LREV.A using FW114WWb07_h2ab_beta1 and previous firmware and the D-LinkNPAPI extension used in the REV.B device using FW208WWb02 and previous firmware. The vulnerability stems from the program failing to verify the X of the SSL server. 509 certificate
