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.

The remote SUSE Linux SLES12 / SLES_SAP12 host has a package installed that is affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:1853-1 advisory.

  - Multiple integer overflows in the NDEF record parser in hostapd before 2.5 and wpa_supplicant before 2.5     allow remote attackers to cause a denial of service (process crash or infinite loop) via a large payload     length field value in an (1) WPS or (2) P2P NFC NDEF record, which triggers an out-of-bounds read.
    (CVE-2015-8041)

  - Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Pairwise Transient Key (PTK) Temporal     Key (TK) during the four-way handshake, allowing an attacker within radio range to replay, decrypt, or     spoof frames. (CVE-2017-13077)

  - Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Group Temporal Key (GTK) during the     four-way handshake, allowing an attacker within radio range to replay frames from access points to     clients. (CVE-2017-13078)

  - Wi-Fi Protected Access (WPA and WPA2) that supports IEEE 802.11w allows reinstallation of the Integrity     Group Temporal Key (IGTK) during the four-way handshake, allowing an attacker within radio range to spoof     frames from access points to clients. (CVE-2017-13079)

  - Wi-Fi Protected Access (WPA and WPA2) that supports IEEE 802.11r allows reinstallation of the Pairwise     Transient Key (PTK) Temporal Key (TK) during the fast BSS transmission (FT) handshake, allowing an     attacker within radio range to replay, decrypt, or spoof frames. (CVE-2017-13082)

  - Wi-Fi Protected Access (WPA and WPA2) allows reinstallation of the Tunneled Direct-Link Setup (TDLS) Peer     Key (TPK) during the TDLS handshake, allowing an attacker within radio range to replay, decrypt, or spoof     frames. (CVE-2017-13086)

  - Wi-Fi Protected Access (WPA and WPA2) that support 802.11v allows reinstallation of the Group Temporal Key     (GTK) when processing a Wireless Network Management (WNM) Sleep Mode Response frame, allowing an attacker     within radio range to replay frames from access points to clients. (CVE-2017-13087)

  - Wi-Fi Protected Access (WPA and WPA2) that support 802.11v allows reinstallation of the Integrity Group     Temporal Key (IGTK) when processing a Wireless Network Management (WNM) Sleep Mode Response frame,     allowing an attacker within radio range to replay frames from access points to clients. (CVE-2017-13088)

  - An issue was discovered in rsn_supp/wpa.c in wpa_supplicant 2.0 through 2.6. Under certain conditions, the     integrity of EAPOL-Key messages is not checked, leading to a decryption oracle. An attacker within range     of the Access Point and client can abuse the vulnerability to recover sensitive information.
    (CVE-2018-14526)

  - The EAP-pwd implementation in hostapd (EAP server) before 2.8 and wpa_supplicant (EAP peer) before 2.8     does not validate fragmentation reassembly state properly for a case where an unexpected fragment could be     received. This could result in process termination due to a NULL pointer dereference (denial of service).
    This affects eap_server/eap_server_pwd.c and eap_peer/eap_pwd.c. (CVE-2019-11555)

  - The implementations of SAE and EAP-pwd in hostapd and wpa_supplicant 2.x through 2.8 are vulnerable to     side-channel attacks as a result of observable timing differences and cache access patterns when Brainpool     curves are used. An attacker may be able to gain leaked information from a side-channel attack that can be     used for full password recovery. (CVE-2019-13377)

  - The implementations of SAE in hostapd and wpa_supplicant are vulnerable to side channel attacks as a     result of observable timing differences and cache access patterns. An attacker may be able to gain leaked     information from a side channel attack that can be used for full password recovery.

    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 EAP-PWD in hostapd EAP Server and wpa_supplicant EAP Peer do not validate the     scalar and element values in EAP-pwd-Commit. This vulnerability may allow an attacker to complete EAP-PWD     authentication without knowing the password. However, unless the crypto library does not implement     additional checks for the EC point, the attacker will not be able to derive the session key or complete     the key exchange. Both hostapd with SAE support and wpa_supplicant with SAE support prior to and including     version 2.4 are affected. Both hostapd with EAP-pwd support and wpa_supplicant with EAP-pwd support prior     to and including version 2.7 are affected. (CVE-2019-9497)

  - The implementations of EAP-PWD in hostapd EAP Server, when built against a crypto library missing explicit     validation on imported elements, do not validate the scalar and element values in EAP-pwd-Commit. An     attacker may be able to use invalid scalar/element values to complete authentication, gaining session key     and network access without needing or learning the password. Both hostapd with SAE support and     wpa_supplicant with SAE support prior to and including version 2.4 are affected. Both hostapd with EAP-pwd     support and wpa_supplicant with EAP-pwd support prior to and including version 2.7 are affected.
    (CVE-2019-9498)

  - The implementations of EAP-PWD in wpa_supplicant EAP Peer, when built against a crypto library missing     explicit validation on imported elements, do not validate the scalar and element values in EAP-pwd-Commit.
    An attacker may complete authentication, session key and control of the data connection with a client.
    Both hostapd with SAE support and wpa_supplicant with SAE support prior to and including version 2.4 are     affected. Both hostapd with EAP-pwd support and wpa_supplicant with EAP-pwd support prior to and including     version 2.7 are affected. (CVE-2019-9499)

  - 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)

Several vulnerabilities were discovered in WPA supplicant / hostapd.
Some of them could only partially be mitigated, please read below for details.

CVE-2019-9495

Cache-based side-channel attack against the EAP-pwd implementation: an attacker able to run unprivileged code on the target machine (including for example JavaScript code in a browser on a smartphone) during the handshake could deduce enough information to discover the password in a dictionary attack.

This issue has only very partially been mitigated against by reducing measurable timing differences during private key operations. More work is required to fully mitigate this vulnerability.

CVE-2019-9497

Reflection attack against EAP-pwd server implementation: a lack of validation of received scalar and elements value in the EAP-pwd-Commit messages could have resulted in attacks that would have been able to complete EAP-pwd authentication exchange without the attacker having to know the password. This did not result in the attacker being able to derive the session key, complete the following key exchange and access the network.

CVE-2019-9498

EAP-pwd server missing commit validation for scalar/element: hostapd didn't validate values received in the EAP-pwd-Commit message, so an attacker could have used a specially crafted commit message to manipulate the exchange in order for hostapd to derive a session key from a limited set of possible values. This could have resulted in an attacker being able to complete authentication and gain access to the network.

This issue could only partially be mitigated.

CVE-2019-9499

EAP-pwd peer missing commit validation for scalar/element:
wpa_supplicant didn't validate values received in the EAP-pwd-Commit message, so an attacker could have used a specially crafted commit message to manipulate the exchange in order for wpa_supplicant to derive a session key from a limited set of possible values. This could have resulted in an attacker being able to complete authentication and operate as a rogue AP.

This issue could only partially be mitigated.

CVE-2019-11555

The EAP-pwd implementation did't properly validate fragmentation reassembly state when receiving an unexpected fragment. This could have lead to a process crash due to a NULL pointer derefrence.

An attacker in radio range of a station or access point with EAP-pwd support could cause a crash of the relevant process (wpa_supplicant or hostapd), ensuring a denial of service.

For Debian 8 'Jessie', these problems have been fixed in version 2.3-1+deb8u8.

We recommend that you upgrade your wpa packages.

Potential side channel attacks in the SAE implementations used by both hostapd and wpa_supplicant (see CVE-2019-9494 and VU#871675). EAP-pwd uses a similar design for deriving PWE from the password and while a specific attack against EAP-pwd is not yet known to be tested, there is no reason to believe that the EAP-pwd implementation would be immune against the type of cache attack that was identified for the SAE implementation. Since the EAP-pwd implementation in hostapd (EAP server) and wpa_supplicant (EAP peer) does not support MODP groups, the timing attack described against SAE is not applicable for the EAP-pwd implementation.

See https://w1.fi/security/2019-2/eap-pwd-side-channel-attack.txt for a detailed description of the bug. Impact : All wpa_supplicant and hostapd versions with EAP-pwd support (CONFIG_EAP_PWD=y in the build configuration and EAP-pwd being enabled in the runtime configuration).

Mathy Vanhoef (NYUAD) and Eyal Ronen (Tel Aviv University & KU Leuven) found multiple vulnerabilities in the WPA implementation found in wpa_supplication (station) and hostapd (access point). These vulnerability are also collectively known as 'Dragonblood'.

  - CVE-2019-9495     Cache-based side-channel attack against the EAP-pwd     implementation: an attacker able to run unprivileged     code on the target machine (including for example     JavaScript code in a browser on a smartphone) during the     handshake could deduce enough information to discover     the password in a dictionary attack.

  - CVE-2019-9497     Reflection attack against EAP-pwd server implementation:
    a lack of validation of received scalar and elements     value in the EAP-pwd-Commit messages could result in     attacks that would be able to complete EAP-pwd     authentication exchange without the attacker having to     know the password. This does not result in the attacker     being able to derive the session key, complete the     following key exchange and access the network.

  - CVE-2019-9498     EAP-pwd server missing commit validation for     scalar/element: hostapd doesn't validate values received     in the EAP-pwd-Commit message, so an attacker could use     a specially crafted commit message to manipulate the     exchange in order for hostapd to derive a session key     from a limited set of possible values. This could result     in an attacker being able to complete authentication and     gain access to the network.

  - CVE-2019-9499     EAP-pwd peer missing commit validation for     scalar/element: wpa_supplicant doesn't validate values     received in the EAP-pwd-Commit message, so an attacker     could use a specially crafted commit message to     manipulate the exchange in order for wpa_supplicant to     derive a session key from a limited set of possible     values. This could result in an attacker being able to     complete authentication and operate as a rogue AP.

Note that the Dragonblood moniker also applies to CVE-2019-9494 and CVE-2014-9496 which are vulnerabilities in the SAE protocol in WPA3.
SAE is not enabled in Debian stretch builds of wpa, which is thus not vulnerable by default.

Due to the complexity of the backporting process, the fix for these vulnerabilities are partial. Users are advised to use strong passwords to prevent dictionary attacks or use a 2.7-based version from stretch-backports (version above 2:2.7+git20190128+0c1e29f-4).

It was discovered that wpa_supplicant and hostapd were vulnerable to a side channel attack against EAP-pwd. A remote attacker could possibly use this issue to recover certain passwords. (CVE-2019-9495)

Mathy Vanhoef discovered that wpa_supplicant and hostapd incorrectly validated received scalar and element values in EAP-pwd-Commit messages. A remote attacker could possibly use this issue to perform a reflection attack and authenticate without the appropriate password.
(CVE-2019-9497, CVE-2019-9498, CVE-2019-9499)

It was discovered that hostapd incorrectly handled obtaining random numbers. In rare cases where the urandom device isn't available, it would fall back to using a low-quality PRNG. This issue only affected Ubuntu 14.04 LTS and Ubuntu 16.04 LTS. (CVE-2016-10743).
