Submit #747429: Tenda AC21 V16.03.08.16 Missing Critical Step in Authenticationinfo

TitelTenda AC21 V16.03.08.16 Missing Critical Step in Authentication
BeschreibungTenda AC21 V16.03.08.16 is susceptible to an Unauthenticated System Log Download vulnerability. This flaw stems from a design deficiency in the Web management interface where the /cgi-bin/DownloadLog and /cgi-bin/DownloadSyslog paths fail to implement any Authentication or Authorization checks when handling HTTP requests. A remote attacker can bypass the login process entirely and induce the device to export sensitive system logs. These logs typically contain: Internal IP addresses and network topology. Device MAC addresses and connection records. System error messages and debugging information. Potential login attempt records (which may include usernames or failed password attempts).
