Security Bulletin

This security bulletin contains one medium risk vulnerability.

1) Input validation error

EUVDB-ID: #VU101950

Risk: Medium

CVSSv4.0: 1.1 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2023-52424

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform spoofing attack.

The vulnerability exists due to SSID confusion error in the IEEE 802.11 standard. A remote attacker can trick the victim into connecting to unintended or untrusted network with Home WEP, Home WPA3 SAE-loop, Enterprise 802.1X/EAP, Mesh AMPE, or FILS. This occurs because the SSID is not always used to derive the pairwise master key or session keys, and because there is not a protected exchange of an SSID during a 4-way handshake.

Mitigation

Install updates from vendor's repository.

Vulnerable software versions

Fedora: 40

wpa_supplicant: before 2.11-1.fc40
