Prior to version 1.4.2, there is a command Injection vulnerability in initialize_kerberos_keytab_file_login(). The vulnerability exists because the code directly interpolates user-controlled input into a shell command and executes it via system() without any sanitization or validation. This issue has been patched in version 1.4.2.\n\n## Affected\n\n- `cryptolib < 1.4.2`\n\n## Remediation\n\nUpgrade past the affected range:\n\n- `cryptolib 1.4.2`","depth":"twilight","depthScore":40,"depthScoreParts":{"impact":40.2,"likelihood":0.2,"exploitation":0,"ransomware":0},"changes":[]}
