CVE-2019-15653Public exploitNetwork attack vector

Credential disclosure via double-MD5 values in login HTML

Published Mar 19, 2020 · Updated Aug 5, 2024

Credential disclosure in Comba AP2600I through A02,0202N00PD2 allows remote attackers to recover login credentials from the login page. The web management login page embeds the username and password as double-MD5 values in HTML rather than keeping the credentials server-side. Unauthenticated network access to that page is sufficient, and reversing the exposed values reveals credentials that can grant administrative device access.
