Account enumeration via distinguishable IAM login failures
Published May 23, 2023 · Updated Jan 17, 2025
User enumeration in HCL Domino AppDev Pack before 1.0.6 allows remote attackers to identify valid users through failed IAM logins. The IAM service returns observably different failure messages depending on whether the submitted username matches a valid account. No authentication or user interaction is required; exposed account validity can focus later password brute-force attempts, but the flaw does not disclose credentials.
