Summary
hashcat fails to restrict command-line options when parsing restore files, allowing attackers to inject output-redirecting options like --outfile and --potfile-path. Attackers can craft restore files with malicious options to append attacker-controlled content to arbitrary files, enabling code execution when targeting shell startup files.
