CVE-2023-3529Network attack vector

Unauthenticated information disclosure via OTP response discrepancy

Published Jul 6, 2023 · Updated Aug 2, 2024

Information disclosure in Rotem Dynamics Rotem CRM 20230729 allows remote attackers to infer application data through the OTP URI. The /LandingPages/api/otp/send endpoint exposes an observable discrepancy when its id parameter is manipulated; the public record does not identify the differing response or data exposed. No authentication or user interaction is required, and the documented consequence is limited to confidentiality because no integrity or availability impact is reported.
