VAR-201606-0182
Vulnerability from variot - Updated: 2025-04-13 23:41The Wi-Fi Protected Setup (WPS) implementation on Corega CG-WLR300GNV and CG-WLR300GNV-W devices does not restrict the number of PIN authentication attempts, which makes it easier for remote attackers to obtain network access via a brute-force attack. CG-WLR300GNV and CG-WLR300GNV-W provided by Corega Inc are wireless LAN routers. The WPS functionality in CG-WLR300GNV Series does not limit PIN authentication attempts, making it susceptible to brute force attacks. Takeshi Okamoto of Kanagawa Institute of Technology and Takaaki Minegishi reported this vulnerability to IPA. JPCERT/CC coordinated with the developer under Information Security Early Warning Partnership.An unauthenticated attacker within wireless range of the device may perform a brute force attack to recover the PIN. Using the recovered PIN, the attacker may gain access to the network. A permission acquisition vulnerability exists in CoregaCG-WLR300GNV and CG-WLR300GNV-W due to the failure of the program to limit the number of authentication requests. CG-WLR300GNV Series routers are prone to an information-disclosure vulnerability. An attacker can exploit this issue to bypass certain security restrictions and aid in brute-force attacks; other attacks may also be possible

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.
Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

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.
