VAR-201512-0517
Vulnerability from variot - Updated: 2025-04-13 23:29Corega CG-WLNCM4G devices provide an open DNS resolver, which allows remote attackers to cause a denial of service (traffic amplification) via crafted queries. CG-WLNCM4G provided by Corega Inc is a network camera. CG-WLNCM4G contains an issue where it may behave as an open resolver. SASABE Tetsuro of The University of Tokyo reported this vulnerability to IPA. JPCERT/CC coordinated with the developer under Information Security Early Warning Partnership.The device may be leveraged for use in a DNS amplification attack and unknowingly become a part of a DDoS attack. Corega CG-WLNCM4G devices has a denial of service vulnerability. CG-WLNCM4G is prone to a denial-of-service vulnerability. An attacker can exploit this issue to cause a denial-of-service condition. Corega CG-WLBARGL is a wireless LAN router produced by Japan's Corega Corporation. A security vulnerability exists in the Corega CG-WLBARAGM device due to the program providing an open DNS resolver

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.
