An attacker can send a sequence of requests to trigger this vulnerability.This denial of service is in the `/action/import_wireguard_cert_file/` API. A specially-crafted network request can lead to denial of service. This problem has been patched in v0.15.1.Ī denial of service vulnerability exists in the web_server hashFirst functionality of Robustel R1510 3.1.16 and 3.3.0. If someone adds users to the Netmaker platform who do not have admin privileges, they can use their auth tokens to run admin-level functions via the API. Prior to version 0.15.1, Improper Authorization functions lead to non-privileged users running privileged API calls. Affected users should upgrade to version 1.38.2 to remediate the issue. Tailscale SSH commands may have been run with a higher privilege group ID than that specified in Tailscale SSH access rules if they met all of the following criteria: the destination node was a FreeBSD device with Tailscale SSH enabled Tailscale SSH access rules permitted access for non-root users and a non-interactive SSH session was used. When accessing a FreeBSD host over Tailscale SSH, the egid of the tailscaled process was used instead of that of the user specified in Tailscale SSH access rules. A difference in the behavior of the FreeBSD `setgroups` system call from POSIX meant that the Tailscale client running on a FreeBSD-based operating system did not appropriately restrict groups on the host when using Tailscale SSH.
A vulnerability identified in the implementation of Tailscale SSH starting in version 1.34.0 and prior to prior to 1.38.2 in FreeBSD allows commands to be run with a higher privilege group ID than that specified in Tailscale SSH access rules. Tailscale is software for using Wireguard and multi-factor authentication (MFA).
