Vulnerability from variot - Updated: 2024-08-18 22:16

TOTOLINK A3002R v4.0.0-B20230531.1404 contains a buffer overflow vulnerability in /bin/boa via formParentControl. TOTOLINK of A3002R Firmware has a classic buffer overflow vulnerability.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. TOTOLINK A3002R is a wireless dual-band Gigabit router produced by China's TOTOLINK Electronics that complies with the latest IEEE802.11ac Wave 2 standard. The vulnerability is caused by the failure of formParentControl to properly verify the length of input data in /bin/boa. Remote attackers can exploit this vulnerability to execute arbitrary code on the system or cause a denial of service attack

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.
