Symantec Endpoint Protection Arbitrary Write - 203

  • A super classic issue for privilege escalation: symbolic links.
  • By creating a symbolic link to the log file from Symantec over a file of our choosing, the file (arbitrary name) will have the information from the log with high privileges.
  • The information, in the log file, can be partially controlled to execute commands. So, easy priv esc.
  • An interesting extra step that had to be done: this was to delete the Logs folder in the UserData section in order for the symbolic link issue to occur.
  • What's the calling for a symbolic link issue? High privilege programs writing to files in potentially user controlled areas.
