Summary
wpa vulnerabilities
Details
Mathy Vanhoef discovered that wpa_supplicant and hostapd incorrectly handled WPA2. A remote attacker could use this issue with key reinstallation attacks to obtain sensitive information. (CVE-2017-13077, CVE-2017-13078, CVE-2017-13079, CVE-2017-13080, CVE-2017-13081, CVE-2017-13082, CVE-2017-13086, CVE-2017-13087, CVE-2017-13088)
Imre Rad discovered that wpa_supplicant and hostapd incorrectly handled invalid characters in passphrase parameters. A remote attacker could use this issue to cause a denial of service. (CVE-2016-4476)
Imre Rad discovered that wpa_supplicant and hostapd incorrectly handled invalid characters in passphrase parameters. A local attacker could use this issue to cause a denial of service, or possibly execute arbitrary code. (CVE-2016-4477)

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.
