A malformed 802.11 probe request frame causes\r\na crash on the Access Point (AP) causing a temporary DoS condition for\r\nwireless clients. Prior successful security association with the\r\nwireless network is not required to cause this condition. The AP\r\nrecovers automatically by restarting itself.\r\n\r\n\r\nAFFECTED ArubaOS VERSIONS\r\n\r\n3.3.1.x, 3.3.2.x, 3.3.3.X, 3.4.2.X, 5.0.X, RN-3.1.X, 3.3.2.x-FIPS and\r\n3.4.2.x-FIPS\r\n\r\n\r\nDETAILS\r\n\r\nAn 802.11 probe request frame is used by wireless clients to discover\r\nwireless networks. A malformed probe request frame may cause a crash on\r\nthe Aruba APs. An attacking station does not need to have completed a\r\nsuccessful security association prior to launching this attack since a\r\nprobe request frame is an unprotected frame. This vulnerability affects\r\nall Aruba APs.\r\n\r\n\r\nIMPACT\r\n\r\nAn attacker can inject a malformed probe request frame and cause an AP\r\nto crash. This causes a service outage for all clients connected to that\r\nAP. The AP recovers automatically by restarting. An attacker could\r\nhowever cause a prolonged DoS condition by flooding the WLAN with\r\nmalicious probe request frames.\r\n\r\nThis vulnerability applies equally to both encrypted and unencrypted\r\nWLANs. This vulnerability does not affect wired devices connected the\r\nAruba Mobility Controller.\r\n\r\nCVSS v2 BASE METRIC SCORE: 6.1 (AV:A/AC:L/Au:N/C:N/I:N/A:C)\r\n\r\n\r\nWORKAROUNDS\r\n\r\nAruba Networks recommends that all customers apply the appropriate\r\npatch(es) as soon as practical. However, in the event that a patch\r\ncannot immediately be applied, the following steps will help to mitigate\r\nthe risk:\r\n\r\n- - - - Disable WIDS functionality in the radio profile for all bands\r\n\r\n rf dot11a-radio-profile <profile>\r\n disable-arm-wids-functions\r\n !\r\n rf dot11g-radio-profile <profile>\r\n disable-arm-wids-functions\r\n !\r\n\r\nSOLUTION\r\n\r\nAruba Networks recommends that all customers apply the appropriate\r\npatch(es) as soon as practical.\r\n\r\nThe following patches have the fix (any newer patch will also have the fix):\r\n\r\n- - - - 3.3.3.8\r\n- - - - 3.4.2.6\r\n- - - - 5.0.2.0\r\n- - - - RN3.1.12\r\n- - - - 3.3.2.20-FIPS\r\n- - - - 3.4.2.3-FIPS\r\n\r\nThe FIPS releases noted above are currently undergoing FIPS\r\ncertification and are available from Aruba on request. Patches for\r\n3.3.1.X and 3.3.2.X releases would be made available on request as well.\r\n\r\nPlease note: We highly recommend that you upgrade your Mobility\r\nController to the latest available patch on the Aruba support site\r\ncorresponding to your currently installed release.\r\n\r\n+----------------------------------------------------\r\n\r\n\r\nAdvisory # 2:\r\n\r\nTITLE\r\n\r\nDot1X Wireless User Authentication Bypass Vulnerability when EAP-TLS\r\nDot1X local termination is enabled on WLAN.\r\n\r\n\r\nSUMMARY\r\n\r\nAn EAP-TLS Dot1X wireless user authentication bypass vulnerability was\r\ndiscovered during standard internal bug reporting procedures in the\r\nAruba Mobility Controller. This vulnerability only affects customers\r\nwith EAP-TLS Dot1X local termination enabled on a WLAN.\r\n\r\n\r\nAFFECTED ArubaOS VERSIONS\r\n\r\n3.3.1.x, 3.3.2.x, 3.3.3.X, 3.4.X, 5.0.X, RN-3.1.X, 3.3.2.x-FIPS and\r\n3.4.2.x-FIPS\r\n\r\n\r\nDETAILS\r\n\r\nAruba Mobility Controllers allow for local termination of EAP-TLS Dot1X\r\nauthentication of wireless users accessing the network and\r\nauthenticating via EAP-TLS. Local Dot1X termination allows rapid\r\ndeployment of WLAN without requiring an external authentication server\r\ncapable of EAP-TLS authentication. A vulnerability in the EAP-TLS Dot1X\r\ntermination component in the Mobility Controller may allow unauthorized\r\nnetwork access to some wireless users.\r\n\r\nEAP-TLS Dot1X termination is not the default setup and must be\r\nconfigured manually for a WLAN before it will be used. Wireless users\r\nauthenticating to an external authentication server are NOT vulnerable\r\nand neither are wired users. Other WLANs on the same Mobility Controller\r\nthat do not use local termination of Dot1X EAP-TLS are NOT affected by\r\nthis vulnerability.\r\n\r\n\r\nIMPACT\r\n\r\nAn EAP-TLS wireless user may be able to gain unauthorized access to a\r\nWLAN configured with local Dot1X termination of EAP-TLS authentications\r\non the Aruba Mobility Controller.\r\n\r\n\r\nCVSS v2 BASE METRIC SCORE: 4.3 (AV:A/AC:M/AU:N/C:P/I:P/A:N)\r\n\r\n\r\nHOW TO IDENTIFY IF YOU ARE VULNERABLE\r\n\r\nIf the following lines exist in your configuration for a particular aaa\r\nprofile and that profile is assigned to an active virtual ap, then you\r\nare vulnerable.\r\n\r\n aaa authentication dot1x <profile>\r\n termination enable\r\n termination eap-type eap-tls\r\n ...\r\n ...\r\n !\r\n\r\n \r\nWORKAROUNDS\r\n\r\nAruba Networks recommends that all customers apply the appropriate\r\npatch(es) as soon as practical. However, in the event that a patch\r\ncannot immediately be applied, the following steps will help to mitigate\r\nthe risk:\r\n\r\n- - - - Disable EAP-TLS Dot1X local termination for wireless users until\r\nsuch time as the patches can be applied and switch to using an external\r\nEAP-TLS server for authenticating wireless users. If local Dot1X\r\ntermination can not be disabled, switch to using another EAP method to\r\nauthenticate wireless users.\r\n\r\n\r\nSOLUTION\r\n\r\nAruba Networks recommends that all customers apply the appropriate\r\npatch(es) as soon as practical.\r\n\r\nThe following patches have the fix (any newer patch will also have the fix):\r\n\r\n- - - - 3.3.3.9\r\n- - - - 3.4.3.1\r\n- - - - 5.0.2.1\r\n- - - - RN3.1.13\r\n- - - - 3.3.2.20-FIPS\r\n- - - - 3.4.2.3-FIPS\r\n\r\nThe FIPS releases noted above are currently undergoing FIPS\r\ncertification and are available from Aruba on request.
