Name of the Vulnerable Software and Affected Versions TP-Link router TL-WR940N V6 version 3.19.1 Build 180119

Description The issue is related to the use of a deprecated MD5 algorithm to hash the admin password used for basic authentication. This could allow a remote attacker to gain unauthorized access to protected information or cause a denial of service.
