"The version of wpa_supplicant installed on the remote host is prior to 2.10 / 2.9. It is, therefore, affected by
multiple vulnerabilities as referenced in the SSA:2022-019-01 advisory.

  - The implementations of EAP-PWD in hostapd and wpa_supplicant are vulnerable to side-channel attacks as a
    result of cache access patterns. All versions of hostapd and wpa_supplicant with EAP-PWD support are
    vulnerable. The ability to install and execute applications is necessary for a successful attack. Memory
    access patterns are visible in a shared cache. Weak passwords may be cracked. Versions of
    hostapd/wpa_supplicant 2.7 and newer, are not vulnerable to the timing attack described in CVE-2019-9494.
    Both hostapd with EAP-pwd support and wpa_supplicant with EAP-pwd support prior to and including version
    2.7 are affected. (CVE-2019-9495)

  - The implementations of SAE in hostapd before 2.10 and wpa_supplicant before 2.10 are vulnerable to side
    channel attacks as a result of cache access patterns. NOTE: this issue exists because of an incomplete fix
    for CVE-2019-9494. (CVE-2022-23303)

  - The implementations of EAP-pwd in hostapd before 2.10 and wpa_supplicant before 2.10 are vulnerable to
    side-channel attacks as a result of cache access patterns. NOTE: this issue exists because of an
    incomplete fix for CVE-2019-9495. (CVE-2022-23304)

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