CVE-2024-36650 (GCVE-0-2024-36650)

Vulnerability from cvelistv5 – Published: 2024-06-11 00:00 – Updated: 2024-08-02 03:37

Summary

TOTOLINK AC1200 Wireless Dual Band Gigabit Router firmware A3100R V4.1.2cu.5247_B20211129, in the cgi function `setNoticeCfg` of the file `/lib/cste_modules/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.

Severity
