Detailsinfo

A vulnerability classified as problematic has been found in WSO2 Identity Server up to 7.0.x. This affects some unknown functionality. The manipulation with an unknown input leads to a information exposure vulnerability. CWE is classifying the issue as CWE-209. The product generates an error message that includes sensitive information about its environment, users, or associated data. This is going to have an impact on confidentiality. The summary by CVE is:

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.
