Summary
wpa vulnerabilities
Details
It was discovered that wpa_supplicant and hostapd were vulnerable to a side channel attack against EAP-pwd. A remote attacker could possibly use this issue to recover certain passwords. (CVE-2019-9495)
Mathy Vanhoef discovered that wpa_supplicant and hostapd incorrectly validated received scalar and element values in EAP-pwd-Commit messages. A remote attacker could possibly use this issue to perform a reflection attack and authenticate without the appropriate password. (CVE-2019-9497, CVE-2019-9498, CVE-2019-9499)
It was discovered that hostapd incorrectly handled obtaining random numbers. In rare cases where the urandom device isn't available, it would fall back to using a low-quality PRNG. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2016-10743)

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.
