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

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
