Sliver C2 framework version 1.7.7 and earlier contains an unhandled panic vulnerability in the operator gRPC handler that allows an attacker controlling a compromised implant to crash the entire teamserver by returning a malformed or empty Download response. Attackers can send zero-length or 1-3 byte data payloads through a hostile implant session to trigger an out-of-bounds slice access in the vendored Binject library's BinaryMagic function, which propagates unrecovered through the operator gRPC interceptor chain and terminates the server process, affecting all connected operators.
