A stack overflow in the checkLoginUser function of TOTOLINK A720R A720R_Firmware v4.1.5cu.470_B20200911 allows attackers to cause a denial of service (DOS).

A vulnerability in the Form_Login function of TOTOLINK A720R A720R_Firmware V4.1.5cu.470_B20200911 allows attackers to bypass authentication.

Cross-site scripting in parent_control.htm in TOTOLINK A3002R version V1.1.1-B20200824 (Important Update, new UI) allows attackers to execute arbitrary JavaScript by modifying the "Description" field and "Service Name" field.

Cross-site scripting in urlfilter.htm in TOTOLINK A3002R version V1.1.1-B20200824 (Important Update, new UI) allows attackers to execute arbitrary JavaScript by modifying the "URL Address" field.

Cross-site scripting in tr069config.htm in TOTOLINK A3002R version V1.1.1-B20200824 (Important Update, new UI) allows attackers to execute arbitrary JavaScript by modifying the "User Name" field or "Password" field.

Directory Indexing in Login Portal of Login Portal of TOTOLINK-A702R-V1.0.0-B20161227.1023 allows attacker to access /add/ , /img/, /js/, and /mobile directories via GET Parameter.

Cross-site scripting in tcpipwan.htm in TOTOLINK A3002R version V1.1.1-B20200824 (Important Update, new UI) allows attackers to execute arbitrary JavaScript by modifying the "Service Name" field.

Cross-site scripting in ddns.htm in TOTOLINK A3002R version V1.1.1-B20200824 (Important Update, new UI) allows attackers to execute arbitrary JavaScript by modifying the "Domain Name" field, "Server Address" field, "User Name/Email", or "Password/Key" field.

Command Injection in TOTOLINK X5000R router with firmware v9.1.0u.6118_B20201102, and TOTOLINK A720R router with firmware v4.1.5cu.470_B20200911 allows remote attackers to execute arbitrary OS commands by sending a modified HTTP request. This occurs because the function executes glibc's system function with untrusted input. In the function, "ip" parameter is directly passed to the attacker, allowing them to control the "ip" field to attack the OS.

Command Injection in TOTOLINK X5000R router with firmware v9.1.0u.6118_B20201102, and TOTOLINK A720R router with firmware v4.1.5cu.470_B20200911 allows remote attackers to execute arbitrary OS commands by sending a modified HTTP request. This occurs because the function executes glibc's system function with untrusted input. In the function, "command" parameter is directly passed to the attacker, allowing them to control the "command" field to attack the OS.

Directory Indexing in Login Portal of Login Portal of TOTOLINK-A702R-V1.0.0-B20161227.1023 allows attacker to access /icons/ directories via GET Parameter.

TOTOLINK A3002RU-V2.0.0 B20190814.1034 allows authenticated remote users to modify the system's 'Run Command'. An attacker can use this functionality to execute arbitrary OS commands on the router.

A cross site scripting (XSS) vulnerability in the error page of Totolink N200RE and N100RE Routers 2.0 allows attackers to execute arbitrary web scripts or HTML via SCRIPT element.

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.

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.

A certain router administration interface (that includes Realtek APMIB 0.11f for Boa 0.94.14rc21) stores cleartext administrative passwords in flash memory and in a file. This affects TOTOLINK 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; Rutek RTK 11N AP through 2019-12-12; Sapido GR297n through 2019-12-12; CIK TELECOM MESH ROUTER through 2019-12-12; KCTVJEJU Wireless AP through 2019-12-12; Fibergate FGN-R2 through 2019-12-12; Hi-Wifi MAX-C300N through 2019-12-12; HCN MAX-C300N through 2019-12-12; T-broad GN-866ac through 2019-12-12; Coship EMTA AP through 2019-12-12; and IO-Data WN-AC1167R through 2019-12-12.

A certain router administration interface (that includes Realtek APMIB 0.11f for Boa 0.94.14rc21) allows remote attackers to retrieve the configuration, including sensitive data (usernames and passwords). This affects TOTOLINK 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; Rutek RTK 11N AP through 2019-12-12; Sapido GR297n through 2019-12-12; CIK TELECOM MESH ROUTER through 2019-12-12; KCTVJEJU Wireless AP through 2019-12-12; Fibergate FGN-R2 through 2019-12-12; Hi-Wifi MAX-C300N through 2019-12-12; HCN MAX-C300N through 2019-12-12; T-broad GN-866ac through 2019-12-12; Coship EMTA AP through 2019-12-12; and IO-Data WN-AC1167R through 2019-12-12.
