CyberRota Analysis
AI-GeneratedThe vulnerability in the SMS OTP flow allows attackers to infer the existence of registered user accounts through error message responses during the OTP initiation process. This issue is particularly concerning for accounts without a configured mobile number, as it enables easier enumeration of valid usernames, potentially leading to brute force attacks and social engineering. Organizations with user authentication systems that utilize SMS OTP should prioritize addressing this weakness to mitigate risks of reputational damage and regulatory non-compliance.

Original NVD Description
The SMS OTP flow fails to adequately handle error messages, allowing an attacker to infer the existence of registered user accounts based on the responses received during the OTP initiation process. This weakness can be exploited by an attacker to discover valid usernames within the system. The impact is amplified for accounts that have not configured a mobile number, as the enumeration is specifically tied to this condition. The discovery of these usernames can facilitate subsequent brute force attacks, social engineering attempts, and information leakage, potentially leading to reputational damage, loss of customer trust, and regulatory non-compliance.
