The remote Alibaba Cloud Linux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALINUX3-SA-2021:0019 advisory.

    Package updates are available for Alibaba Cloud Linux 3 that fix the following vulnerabilities:

    CVE-2019-16275:
    hostapd before 2.10 and wpa_supplicant before 2.10 allow an incorrect indication of disconnection in     certain situations because source address validation is mishandled. This is a denial of service that     should have been prevented by PMF (aka management frame protection). The attacker must send a crafted     802.11 frame from a location that is within the 802.11 communications range.

    CVE-2021-0326:
    In p2p_copy_client_info of p2p.c, there is a possible out of bounds write due to a missing bounds check.
    This could lead to remote code execution if the target device is performing a Wi-Fi Direct search, with no     additional execution privileges needed. User interaction is not needed for exploitation.Product:
    AndroidVersions: Android-10 Android-11 Android-8.1 Android-9Android ID: A-172937525

    CVE-2021-27803:
    A vulnerability was discovered in how p2p/p2p_pd.c in wpa_supplicant before 2.10 processes P2P (Wi-Fi     Direct) provision discovery requests. It could result in denial of service or other impact (potentially     execution of arbitrary code), for an attacker within radio range.

Tenable has extracted the preceding description block directly from the Alibaba Cloud Linux security advisory.

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

hostapd (and wpa_supplicant when controlling AP mode) did not perform sufficient source address validation for some received Management frames and this could result in ending up sending a frame that caused associated stations to incorrectly believe they were disconnected from the network even if management frame protection (also known as PMF) was negotiated for the association. This could be considered to be a denial of service vulnerability since PMF is supposed to protect from this type of issues.

For Debian 8 'Jessie', this problem has been fixed in version 2.3-1+deb8u9.

We recommend that you upgrade your wpa packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

This update for hostapd fixes the following issues :

  - CVE-2021-30004: forging attacks may occur because     AlgorithmIdentifier parameters are mishandled in     tls/pkcs1.c and tls/x509v3.c (boo#1184348)

  - CVE-2020-12695: UPnP SUBSCRIBE misbehavior in hostapd     WPS AP (boo#1172700)

  - CVE-2019-16275: AP mode PMF disconnection protection     bypass (boo#1150934) 

  - added AppArmor profile (source     apparmor-usr.sbin.hostapd)

The version of wpa_supplicant installed on the remote host is prior to 2.9. It is, therefore, affected by multiple vulnerabilities as referenced in the SSA:2021-362-01 advisory.

  - hostapd before 2.10 and wpa_supplicant before 2.10 allow an incorrect indication of disconnection in     certain situations because source address validation is mishandled. This is a denial of service that     should have been prevented by PMF (aka management frame protection). The attacker must send a crafted     802.11 frame from a location that is within the 802.11 communications range. (CVE-2019-16275)

  - The Open Connectivity Foundation UPnP specification before 2020-04-17 does not forbid the acceptance of a     subscription request with a delivery URL on a different network segment than the fully qualified event-     subscription URL, aka the CallStranger issue. (CVE-2020-12695)

  - In p2p_copy_client_info of p2p.c, there is a possible out of bounds write due to a missing bounds check.
    This could lead to remote code execution if the target device is performing a Wi-Fi Direct search, with no     additional execution privileges needed. User interaction is not needed for exploitation.Product:
    AndroidVersions: Android-10 Android-11 Android-8.1 Android-9Android ID: A-172937525 (CVE-2021-0326)

  - In wpas_ctrl_msg_queue_timeout of ctrl_iface_unix.c, there is a possible memory corruption due to a use     after free. This could lead to local escalation of privilege with System execution privileges needed. User     interaction is not needed for exploitation.Product: AndroidVersions: Android-11Android ID: A-168314741     (CVE-2021-0535)

  - A vulnerability was discovered in how p2p/p2p_pd.c in wpa_supplicant before 2.10 processes P2P (Wi-Fi     Direct) provision discovery requests. It could result in denial of service or other impact (potentially     execution of arbitrary code), for an attacker within radio range. (CVE-2021-27803)

  - In wpa_supplicant and hostapd 2.9, forging attacks may occur because AlgorithmIdentifier parameters are     mishandled in tls/pkcs1.c and tls/x509v3.c. (CVE-2021-30004)

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

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

According to the version of the wpa_supplicant package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - hostapd before 2.10 and wpa_supplicant before 2.10     allow an incorrect indication of disconnection in     certain situations because source address validation is     mishandled. This is a denial of service that should     have been prevented by PMF (aka management frame     protection). The attacker must send a crafted 802.11     frame from a location that is within the 802.11     communications range.(CVE-2019-16275)

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-4136-1 advisory.

    It was discovered that wpa_supplicant incorrectly handled certain management frames. An attacker could     possibly use this issue to cause a denial of service.

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

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

Security fix CVE-2019-16275 (AP mode PMF disconnection protection bypass)

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Two vulnerabilities were found in the WPA protocol implementation found in wpa_supplication (station) and hostapd (access point).

  - CVE-2019-13377     A timing-based side-channel attack against WPA3's     Dragonfly handshake when using Brainpool curves could be     used by an attacker to retrieve the password.

  - CVE-2019-16275     Insufficient source address validation for some received     Management frames in hostapd could lead to a denial of     service for stations associated to an access point. An     attacker in radio range of the access point could inject     a specially constructed unauthenticated IEEE 802.11     frame to the access point to cause associated stations     to be disconnected and require a reconnection to the     network.

This update for wpa_supplicant fixes the following issues :

CVE-2021-0326: P2P group information processing vulnerability (bsc#1181777).

CVE-2019-16275: AP mode PMF disconnection protection bypass (bsc#1150934)
