| 标题 | Tenda AC21 V16.03.08.16 Missing Critical Step in Authentication |
|---|
| 描述 | Tenda 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). |
