Prior to 7.1.2, the two-factor login step let an attacker try unlimited password guesses for any account without triggering Zammad's normal lockout or rate limiting. The response also revealed whether a guess was correct, even before two-factor authentication was checked. This made it possible to brute-force weak or reused passwords. This issue is fixed in version 7.1.2.\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.","depth":"sunlit","depthScore":38,"depthScoreParts":{"impact":38,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
