AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N

Name of the Vulnerable Software and Affected Versions WPA2 (affected versions not specified)

Description The issue is related to errors in cryptographic key management in the WPA2 protocol, which secures Wi-Fi networks. An attacker within the Wi-Fi network's range can exploit this to access encrypted information transmitted over the wireless network, such as decrypting or injecting data packets, or hijacking TCP connections. This is achieved by replaying the Fast BSS Transition Reassociation request and re-establishing the pairwise key during its processing. The vulnerability allows an attacker to replay, decrypt, or spoof frames by reinstalling the Pairwise Transient Key (PTK) Temporal Key (TK) during the fast BSS transmission (FT) handshake.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
