* wpa_supplicant: fix CVE-2018-14526John Crispin2018-08-101-0/+43
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Unauthenticated EAPOL-Key decryption in wpa_supplicant Published: August 8, 2018 Identifiers: - CVE-2018-14526 Latest version available from: https://w1.fi/security/2018-1/ Vulnerability A vulnerability was found in how wpa_supplicant processes EAPOL-Key frames. It is possible for an attacker to modify the frame in a way that makes wpa_supplicant decrypt the Key Data field without requiring a valid MIC value in the frame, i.e., without the frame being authenticated. This has a potential issue in the case where WPA2/RSN style of EAPOL-Key construction is used with TKIP negotiated as the pairwise cipher. It should be noted that WPA2 is not supposed to be used with TKIP as the pairwise cipher. Instead, CCMP is expected to be used and with that pairwise cipher, this vulnerability is not applicable in practice. When TKIP is negotiated as the pairwise cipher, the EAPOL-Key Key Data field is encrypted using RC4. This vulnerability allows unauthenticated EAPOL-Key frames to be processed and due to the RC4 design, this makes it possible for an attacker to modify the plaintext version of the Key Data field with bitwise XOR operations without knowing the contents. This can be used to cause a denial of service attack by modifying GTK/IGTK on the station (without the attacker learning any of the keys) which would prevent the station from accepting received group-addressed frames. Furthermore, this might be abused by making wpa_supplicant act as a decryption oracle to try to recover some of the Key Data payload (GTK/IGTK) to get knowledge of the group encryption keys. Full recovery of the group encryption keys requires multiple attempts (128 connection attempts per octet) and each attempt results in disconnection due to a failure to complete the 4-way handshake. These failures can result in the AP/network getting disabled temporarily or even permanently (requiring user action to re-enable) which may make it impractical to perform the attack to recover the keys before the AP has already changes the group keys. By default, wpa_supplicant is enforcing at minimum a ten second wait time between each failed connection attempt, i.e., over 20 minutes waiting to recover each octet while hostapd AP implementation uses 10 minute default for GTK rekeying when using TKIP. With such timing behavior, practical attack would need large number of impacted stations to be trying to connect to the same AP to be able to recover sufficient information from the GTK to be able to determine the key before it gets changed. Vulnerable versions/configurations All wpa_supplicant versions. Acknowledgments Thanks to Mathy Vanhoef of the imec-DistriNet research group of KU Leuven for discovering and reporting this issue. Possible mitigation steps - Remove TKIP as an allowed pairwise cipher in RSN/WPA2 networks. This can be done also on the AP side. - Merge the following commits to wpa_supplicant and rebuild: WPA: Ignore unauthenticated encrypted EAPOL-Key data This patch is available from https://w1.fi/security/2018-1/ - Update to wpa_supplicant v2.7 or newer, once available Signed-off-by: John Crispin <john@phrozen.org>

* hostapd: explicitly set beacon interval for wpa_supplicantSven Eckelmann2017-12-131-0/+1
| | | | | | | | | | | | | | | | The beacon_int is currently set explicitly for hostapd and when LEDE uses iw to join and IBSS/mesh. But it was not done when wpa_supplicant was used to join an encrypted IBSS or mesh. This configuration is required when an AP interface is configured together with an mesh interface. The beacon_int= line must therefore be re-added to the wpa_supplicant config. The value is retrieved from the the global variable.

* hostapd: set mcast_rate in mesh modeSven Eckelmann2017-12-131-0/+68
| | | | | | | | | | | | | | | | | | | The wpa_supplicant code for IBSS allows to set the mcast rate. It is recommended to increase this value from 1 or 6 Mbit/s to something higher when using a mesh protocol on top which uses the multicast packet loss as indicator for the link quality. This setting was unfortunately not applied for mesh mode. But it would be beneficial when wpa_supplicant would behave similar to IBSS mode and set this argument during mesh join like authsae already does. At least it is helpful for companies/projects which are currently switching to 802.11s (without mesh_fwding and with mesh_ttl set to 1) as replacement for IBSS because newer drivers seem to support 802.11s but not IBSS anymore.

* hostapd: fix reload frequency change patchAbhilash Tuse2017-12-132-7/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When sta is configured, hostapd receives 'stop' and 'update' command from wpa_supplicant. In the update command, hostapd gets sta parameters with which it configures ap. Problem is, with the default wireless configuration: mode:11g freq:2.4GHz channel:1 If sta is connected to 5GHz network, then ap does not work. Ideally with 340-reload_freq_change.patch hostapd should reload the frequency changes and start ap in 5GHz, but ap becomes invisible in the network. This issue can be reproduced with following /etc/config/wireless: config wifi-device radio0 option type mac80211 option channel 1 option hwmode 11g option path 'virtual/uccp420/uccwlan' option htmode 'none' config wifi-iface 'ap' option device 'radio0' option encryption 'none' option mode 'ap' option network 'ap' option ssid 'MyTestNet' option encryption none config wifi-iface 'sta' option device radio0 option network sta option mode sta option ssid TestNet-5G option encryption psk2 option key 12345 This change updates current_mode structure based on configured hw_mode received from wpa_supplicant.

* hostapd: Expose the tdls_prohibit option to UCITimo Sigurdsson2017-12-071-1/+6
| | | | | | | | | | | | | | | | | wpa_disable_eapol_key_retries can't prevent attacks against the Tunneled Direct-Link Setup (TDLS) handshake. Jouni Malinen suggested that the existing hostapd option tdls_prohibit can be used to further complicate this possibility at the AP side. tdls_prohibit=1 makes hostapd advertise that use of TDLS is not allowed in the BSS. Note: If an attacker manages to lure both TDLS peers into a fake AP, hiding the tdls_prohibit advertisement from them, it might be possible to bypass this protection. Make this option configurable via UCI, but disabled by default. Signed-off-by: Timo Sigurdsson <public_timo.s@silentcreek.de> (cherry picked from commit 6515887ed9b3f312635409702113dca7c14043e5)
* hostapd: add wpa_disable_eapol_key_retries optionStijn Tintel2017-10-172-1/+6
| | | | | | | | | | | | | | | Commit b6c3931ad6554357a108127797c8d7097a93f18f introduced an AP-side workaround for key reinstallation attacks. This option can be used to mitigate KRACK on the station side, in case those stations cannot be updated. Since many devices are out there will not receive an update anytime soon (if at all), it makes sense to include this workaround. Unfortunately this can cause interoperability issues and reduced robustness of key negotiation, so disable the workaround by default, and add an option to allow the user to enable it if he deems necessary.

* mac80211, hostapd: always explicitly set beacon intervalMatthias Schiffer2017-05-272-4/+3
| | | | | | | | | | | | | | | | One of the latest mac80211 updates added sanity checks, requiring the beacon intervals of all VIFs of the same radio to match. This often broke AP+11s setups, as these modes use different default intervals, at least in some configurations (observed on ath9k). Instead of relying on driver or hostapd defaults, change the scripts to always explicitly set the beacon interval, defaulting to 100. This also applies the beacon interval to 11s interfaces, which had been forgotten before. VIF-specific beacon_int setting is removed from hostapd.sh. Fixes FS#619.

* hostapd: add legacy_rates option to disable 802.11b data rates.Nick Lowe2017-05-271-8/+20
| | | | | | | | | | | | | | | | | | Setting legacy_rates to 0 disables 802.11b data rates. Setting legacy_rates to 1 enables 802.11b data rates.

The rationale for the change, stronger now than in 2014, can be found in: https://mentor.ieee.org/802.11/dcn/14/11-14-0099-00-000m-renewing-2-4ghz-band.pptx The balance of equities between compatibility with b clients and the detriment to the 2.4 GHz ecosystem as a whole strongly favors disabling b rates by default.

* hostapd: backport support for sending debug messages to the syslogRafał Miłecki2017-02-056-24/+169
| | | | | | | | | | | | | | | | | It wasn't possible to read hostapd wpa_printf messages unless running hostapd manually. It was because hostapd was printing them using vprintf and not directly to the syslog. We were trying to workaround this problem by redirecting STDIN_FILENO and STDOUT_FILENO but it was working only for the initialization phase. As soon as hostapd did os_daemonize our solution stopped working. Please note despite the subject this change doesn't affect debug level messages only but just everything printed by hostapd with wpa_printf including MSG_ERROR-s. This makes it even more important as reading error messages can be quite useful for debugging. Signed-off-by: Rafał Miłecki <rafal@milecki.pl>
