 - ------------------------------------------------------------------------- Debian LTS Advisory DLA-3743-1 [email protected] https://www.debian.org/lts/security/ Chris Lamb February 27, 2024 https://wiki.debian.org/LTS
 - -------------------------------------------------------------------------

 Package : wpa Version : 2:2.7+git20190128+0c1e29f-6+deb10u4 CVE ID : CVE-2023-52160 Debian Bug : 1064061

 It was discovered that there was a potential authentication bypass vulnerability in wpa, a set of tools including the widely-used wpasupplicant client for authenticating with WPA and WPA2 wireless networks.

 For an attack to have been successful, wpasupplicant must have been configured to not verify the network's TLS certificate during Phase 1 of the authentication cycle; a eap_peap_decrypt vulnerability could have been used to skip Phase 2 authentication by sending an EAP-TLV Success packet instead of starting Phase 2.

 For Debian 10 buster, this problem has been fixed in version 2:2.7+git20190128+0c1e29f-6+deb10u4.

 We recommend that you upgrade your wpa packages.

 For the detailed security status of wpa please refer to its security tracker page at:
 https://security-tracker.debian.org/tracker/wpa

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade the hostapd packages.
