This affects the function quick_capture of the file pyshark_mcp.py. The manipulation results in os command injection. The attack may be launched remotely. The exploit has been released to the public and may be used for attacks. This product operates on a rolling release basis, ensuring continuous delivery. Consequently, there are no version details for either affected or updated releases.
