Very low probability of exploitation
EPSS predicts the probability of exploitation in the next 30 days based on real-world threat data, complementing CVSS severity scores with actual risk assessment.
What kind of vulnerability is it? Who is impacted?
MinIO AIStor's STS (Security Token Service) AssumeRoleWithLDAPIdentity endpoint is vulnerable to LDAP credential brute-forcing due to two combined weaknesses: (1) distinguishable error responses that enable username enumeration, and (2) absence of rate limiting on authentication attempts. An unauthenticated network attacker can enumerate valid LDAP usernames and then perform unlimited password guessing to obtain temporary AWS-style STS credentials, gaining access to the victim's S3 buckets and objects.
All deployments with LDAP configured running an affected version are impacted.
There are two vulnerabilities:
When exploited together, an attacker can:
AccessKeyId, SecretAccessKey, SessionToken) with full access to the victim user's S3 resources.All MinIO releases through the final release of the minio/minio open-source project.
