CVE-2019-15656Public exploitNetwork attack vector

ISP credential disclosure via login-page variables

Published Mar 19, 2020 · Updated Aug 5, 2024

Information disclosure in D-Link DSL-2875AL and DSL-2877AL through 1.00.05 allows remote attackers to read ISP credentials. The unauthenticated index.asp login page renders username_v and password_v from WAN configuration directly into client-side source. Network access to the management interface is required; D-Link states that this reported issue does not affect either modem.
