TOTOLINK A3002RU V2.1.1-B20211108.1455 was discovered to contain a stack-based buffer overflow via the vpnUser or vpnPassword parameters in the formFilter function.

TOTOLINK A3002RUV3 V3.0.0-B20220304.1804 was discovered to contain a stack-based buffer overflow via the staticipv6 parameter in the formIpv6Setup function.

Totolink AC1200 Wireless Dual Band Gigabit Router A3002RUV3 Firmware V3.0.0-B20230809.1615 is vulnerable to Buffer Overflow. The "boa" program allows attackers to modify the value of the "vwlanidx" field via "formMultiAP". This can lead to a stack overflow through the "formWlEncrypt" CGI function by constructing malicious HTTP requests and passing a WLAN SSID value exceeding the expected length, potentially resulting in command execution or denial of service attacks.

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.

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.
