Vulnerability from github – Published: 2022-05-24 17:36 – Updated: 2022-08-07 00:00

Details

Askey AP5100W devices through AP5100W_Dual_SIG_1.01.097 are affected by WPS PIN offline brute-force cracking. This arises because of issues with the random number selection for the Diffie-Hellman exchange. By capturing an attempted (and even failed) WPS authentication attempt, it is possible to brute force the overall authentication exchange. This allows an attacker to obtain the recovered WPS PIN in minutes or even seconds, and eventually obtain the Wi-Fi PSK key, gaining access to the Wi=Fi network.

Severity

5.9 (Medium)

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.
