FatPipe Networks WARP/IPVPN/MPVPN 10.2.2 CSRF Add Admin Exploit

Description

Title: FatPipe Networks WARP/IPVPN/MPVPN 10.2.2 CSRF Add Admin Exploit Advisory ID: [ZSL-2021-5681](<ZSL-2021-5681.php>) Type: Local/Remote Impact: Cross-Site Scripting Risk: (4/5) Release Date: 27.09.2021 ##### Summary FatPipe Networks invented the concept of router-clustering, which provides the highest level of reliability, redundancy, and speed of Internet traffic for Business Continuity and communications. FatPipe WARP achieves fault tolerance for companies by creating an easy method of combining two or more Internet connections of any kind over multiple ISPs. FatPipe utilizes all paths when the lines are up and running, dynamically balancing traffic over the multiple lines, and intelligently failing over inbound and outbound IP traffic when ISP services and/or components fail. FatPipe IPVPN balances load and provides reliability among multiple managed and CPE based VPNs as well as dedicated private networks. FatPipe IPVPN can also provide you an easy low-cost migration path from private line, Frame or Point-to-Point networks. You can aggregate multiple private, MPLS and public networks without additional equipment at the provider's site. FatPipe MPVPN, a patented router clustering device, is an essential part of Disaster Recovery and Business Continuity Planning for Virtual Private Network (VPN) connectivity. It makes any VPN up to 900% more secure and 300% times more reliable, redundant and faster. MPVPN can take WANs with an uptime of 99.5% or less and make them 99.999988% or higher, providing a virtually infallible WAN. MPVPN dynamically balances load over multiple lines and ISPs without the need for BGP programming. MPVPN aggregates up to 10Gbps - 40Gbps of bandwidth, giving you all the reliability and speed you need to keep your VPN up and running despite failures of service, line, software, or hardware. ##### Description The application interface allows users to perform certain actions via HTTP requests without performing any validity checks to verify the requests.
