TITLE

D-Link DIR-850L Vulnerabilities related to the use of hard-coded credentials in device firmware

Trust: 0.8

sources: JVNDB: JVNDB-2017-008134

DESCRIPTION

D-Link DIR-850L REV. A (with firmware through FW114WWb07_h2ab_beta1) and REV. B (with firmware through FW208WWb02) devices use the same hardcoded /etc/stunnel.key private key across different customers' installations, which allows remote attackers to defeat the HTTPS cryptographic protection mechanisms by leveraging knowledge of this key from another installation. D-Link DIR-850L Device firmware contains a vulnerability related to the use of hard-coded credentials.Information may be obtained. D-LinkDIR-850LREV.A and REV.B are both D-Link wireless router products. This vulnerability is caused by different users using the same hard-coded private key during installation ( /etc/stunnel.key). This vulnerability could be exploited by a remote attacker to compromise the HTTPS encryption protection mechanism. key (/etc/stunnel.key)
