TOTOLINK A3100R V4.1.2cu.5050B20200504 and V4.1.2cu.5247B20211129 were discovered to contain a stack overflow via the startTime and endTime parameters in the function setParentalRules. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted POST request.
In totolink a3100r V5.9c.4577, the hard-coded telnet password can be discovered from official released firmware. An attacker, who has connected to the Wi-Fi, can easily telnet into the target with root shell if the telnet is function turned on.
Totolink A3100R V5.9c.4577 suffers from Use of Insufficiently Random Values via the web configuration. The SESSIONID is predictable. An attacker can hijack a valid session and conduct further malicious operations.
TOTOLINK AC1200 Wireless Dual Band Gigabit Router firmware A3100R V4.1.2cu.5247B20211129, in the cgi function setNoticeCfg of the file /lib/cstemodules/system.so, the length of the user input string NoticeUrl is not checked. This can lead to a buffer overflow, allowing attackers to construct malicious HTTP or MQTT requests to cause a denial-of-service attack.
