| Titre | minio <=RELEASE.2025-10-15T17-29-55Z Improper Restriction of Excessive Authentication Attempts |
|---|
| Description | MinIO's STS (Security Token Service) LDAP authentication endpoint (AssumeRoleWithLDAPIdentity) contains two vulnerabilities that, when combined, allow unauthenticated attackers to compromise LDAP user accounts:
User Enumeration: Distinct error messages reveal whether a username exists
No Rate Limiting: Unlimited authentication attempts without throttling or lockout
Successful exploitation grants attackers temporary AWS-style credentials (AccessKeyId/SecretAccessKey/SessionToken) with full access to the victim's S3 buckets. |
