AlienVault OTX Vulnerabilities

AlienVault OTX Malware

The Access Point functionality in eapol_auth_key_handle in eapol.c in iNet wireless daemon (IWD) before 2.14 allows attackers to gain unauthorized access to a protected Wi-Fi network. An attacker can complete the EAPOL handshake by skipping Msg2/4 and instead sending Msg4/4 with an all-zero key.

CVE-2023-52161 is a vulnerability identified in the iNet wireless daemon (IWD), a Linux-based wireless management daemon used to handle Wi-Fi connections, particularly in embedded and Linux environments. The flaw resides in the Access Point functionality within the EAPOL (Extensible Authentication Protocol over LAN) handshake implementation, specifically in the function eapol_auth_key_handle in eapol.c. Normally, the EAPOL handshake involves a four-message exchange to securely authenticate clients to a protected Wi-Fi network. This vulnerability allows an attacker to bypass part of this handshake by skipping message 2 of 4 and sending message 4 of 4 with an all-zero key. This manipulation tricks the Access Point into completing the handshake and granting network access without proper authentication. The vulnerability does not require any privileges or user interaction, making it remotely exploitable over the network. The CVSS 3.1 score of 7.5 reflects its high impact on confidentiality, as unauthorized users can gain access to protected networks, though it does not affect integrity or availability directly. No patches were linked in the provided data, but the vulnerability is fixed in IWD version 2.14 and later. There are no known exploits in the wild at this time, but the ease of exploitation and potential impact make it a critical issue for organizations relying on IWD for wireless access point management.
