Error: “Gateway is not Reachable” or Connection Goes Down After the VPN Tunnel is Established

Citrix Leave a comment

  • Citrix Virtual Adapter is registered as an Ethernet adapter. Starting with Windows 8, the WCMSVC (Windows Connection Manager) disconnects low speed connections because an Ethernet Adapter is seen as more reliable and provides better performance compared to other adapters. That’s the reason, Wi-Fi, 3G/4G adapters get disconnected. But those connections are needed for actual communication with VPN gateway, VPN plugin shows “Gateway is not reachable”.

    Cisco Wireless LAN Controller CAPWAP Denial of Service Vulnerability

    Cisco Leave a comment

    A vulnerability in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol handler of Cisco Wireless LAN Controller (WLC) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.

    The vulnerability is due to insufficient validation of CAPWAP packets. An attacker could exploit this vulnerability by sending a malformed CAPWAP packet to an affected device. A successful exploit could allow the attacker to cause the affected device to restart, resulting in a DoS condition.

    Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.

    This advisory is available at the following link:

    This advisory is part of the April 2020 Cisco Aironet AP, Mobility Express, and WLC Software Security Advisory Bundled Publication, which includes four Cisco Security Advisories that describe four vulnerabilities. For a complete list of the advisories and links to them, see Cisco Event Response: April 2020 Cisco Aironet AP, Mobility Express and WLC Software Security Advisory Bundled Publication.

    Wi-Fi Protected Network and Wi-Fi Protected Network 2 Information Disclosure Vulnerability

    Cisco Leave a comment

    On February 26th, 2020, researchers Štefan Svorencík and Robert Lipovsky disclosed a vulnerability in the implementation of the wireless egress packet processing of certain Broadcom Wi-Fi chipsets. This vulnerability could allow an unauthenticated, adjacent attacker to decrypt Wi-Fi frames without the knowledge of the Wireless Protected Access (WPA) or Wireless Protected Access 2 (WPA2) Pairwise Temporal Key (PTK) used to secure the Wi-Fi network.

    The vulnerability exists because after an affected device handles a disassociation event it could send a limited number of Wi-Fi frames encrypted with a static, weak PTK. An attacker could exploit this vulnerability by acquiring these frames and decrypting them with the static PTK. A successful exploit could allow the attacker to decrypt Wi-Fi frames without the knowledge of the security session establishment used to secure the Wi-Fi network.

    Multiple Cisco wireless products are affected by this vulnerability.

    Cisco will release software updates that address this vulnerability. There are no workarounds that addresses this vulnerability.

    Dell EMC Streaming Data Platform Enables Insights for Streaming Data from the Edge

    Dell Security Leave a comment
    Streaming Data Creates Massive Potential for Organizations Across Industries According to IDC, more than a quarter of data created in the global datasphere will be real-time in nature by 2025.[i] Much of that data will come from the edge, originate from sensors, cameras and drones, and come in the form of a continuous data stream. Streaming data creates additional complexities in the already intricate world of unstructured data. With its tendency to vary in volume and boundaries and with timestamps that can fluctuate out of order, the need for a Data First infrastructure – where organizations … READ MORE
