TOTOLINK A3002ru Firmware

System command injection in formAliasIp in TOTOLINK A3002RU version 1.0.8 allows attackers to execute system commands via the "subnet" POST parameter.

System command injection in fromNtp in TOTOLINK A3002RU version 1.0.8 allows attackers to execute system commands via the "ntpServerIp2" POST parameter. Certain payloads cause the device to become permanently inoperable.

System command injection in formAliasIp in TOTOLINK A3002RU version 1.0.8 allows attackers to execute system commands via the "ipAddr" POST parameter.

System command injection in formDlna in TOTOLINK A3002RU version 1.0.8 allows attackers to execute system commands via the "ftpUser" POST parameter.

System command injection in formDlna in TOTOLINK A3002RU version 1.0.8 allows attackers to execute system commands via the "sambaUser" POST parameter.

On certain TOTOLINK Realtek SDK based routers, the CAPTCHA text can be retrieved via an {"topicurl":"setting/getSanvas"} POST to the boafrm/formLogin URI, leading to a CAPTCHA bypass. (Also, the CAPTCHA text is not needed once the attacker has determined valid credentials. The attacker can perform router actions via HTTP requests with Basic Authentication.) This affects A3002RU through 2.0.0, A702R through 2.1.3, N301RT through 2.1.6, N302R through 3.4.0, N300RT through 3.4.0, N200RE through 4.0.0, N150RT through 3.4.0, and N100RE through 3.4.0.

Incorrect access control in formPasswordSetup in TOTOLINK A3002RU version 1.0.8 allows attackers to change the admin user's password via an unauthenticated POST request.

TOTOLINK A3002RU V3.0.0-B20220304.1804 has a hardcoded password for root in /etc/shadow.sample.

TOTOLINK AC1200 Wireless Router A3002RU V2.1.1-B20230720.1011 is vulnerable to Buffer Overflow. The formWlEncrypt CGI handler in the boa program fails to limit the length of the wlan_ssid field from user input. This allows attackers to craft malicious HTTP requests by supplying an excessively long value for the wlan_ssid field, leading to a stack overflow. This can be further exploited to execute arbitrary commands or launch denial-of-service attacks.

On certain TOTOLINK Realtek SDK based routers, an authenticated attacker may execute arbitrary OS commands via the sysCmd parameter to the boafrm/formSysCmd URI, even if the GUI (syscmd.htm) is not available. This allows for full control over the device's internals. This affects A3002RU through 2.0.0, A702R through 2.1.3, N301RT through 2.1.6, N302R through 3.4.0, N300RT through 3.4.0, N200RE through 4.0.0, N150RT through 3.4.0, N100RE through 3.4.0, and N302RE 2.0.2.
