GDB Server Detection
High Nessus Plugin ID 21245
SynopsisArbitrary code can be executed on the remote host.
DescriptionThe remote host is running gdbserver, a program which can be used to run the GDB debugger on a different machine than the one which is running the program being debugged.
Since gdbserver offers no authentication whatsoever, an attacker may connect to this port, change the value of the registers and the memory of the process being debugged, and therefore be able to execute arbitrary code on the remote host with the privileges of the process being debugged.
SolutionFilter incoming traffic to this port or disable this service.
