CVE ID : CVE-2017-13077 CVE-2017-13078 CVE-2017-13079 CVE-2017-13080 | |

CVE-2017-13088 | |
Mathy Vanhoef of the imec-DistriNet research group of KU Leuven discovered | |
multiple vulnerabilities in the WPA protocol, used for authentication in | |
wireless networks. Those vulnerabilities applies to both the access point | |
(implemented in hostapd) and the station (implemented in wpa_supplicant). | |
An attacker exploiting the vulnerabilities could force the vulnerable system to | |
reuse cryptographic session keys, enabling a range of cryptographic attacks | |
against the ciphers used in WPA1 and WPA2. | |
More information can be found in the researchers's paper, Key Reinstallation | |
Attacks: Forcing Nonce Reuse in WPA2. | |
