This vulnerability exists in the Wave 2.0 due to insufficient encryption of sensitive data received at the API response. An authenticated remote attacker could exploit this vulnerability by manipulating API input parameters through API request URL/payload leading to unauthorized access to sensitive information belonging to other users.

This vulnerability exists in the Wave 2.0 due to missing rate limiting on OTP requests in an API endpoint. An authenticated remote attacker could exploit this vulnerability by sending multiple OTP request through vulnerable API endpoint which could lead to the OTP bombing/flooding on the targeted system.

This vulnerability exists in the Wave 2.0 due to missing restrictions for excessive failed authentication attempts on its API based login. A remote attacker could exploit this vulnerability by conducting a brute force attack against legitimate user OTP, MPIN or password, which could lead to gain unauthorized access and compromise other user accounts.

This vulnerability exists in the Wave 2.0 due to improper authorization checks on certain API endpoints. An authenticated remote attacker could exploit this vulnerability by manipulating API input parameters to gain unauthorized access and perform malicious activities on other user accounts.

This vulnerability exists in the Wave 2.0 due to improper exception handling for invalid inputs at certain API endpoint. An authenticated remote attacker could exploit this vulnerability by providing invalid inputs for “userId” parameter in the API request leading to generation of error message containing sensitive information on the targeted system.

This vulnerability exists in Aero due to improper implementation of OTP validation mechanism in certain API endpoints. An authenticated remote attacker could exploit this vulnerability by intercepting and manipulating the responses exchanged during the second factor authentication process. Successful exploitation of this vulnerability could allow the attacker to bypass OTP verification for accessing other user accounts.
