Summary

WSO2 Identity Server from 5.11.0 before 5.11.0.372, from 6.0.0 before 6.0.0.227, and from 6.1.0 before 6.1.0.219 does not enforce a default expiry time for SMS one-time passwords used in multi-factor authentication. Unused OTPs remain valid indefinitely, so an attacker can keep guessing a code without any time limit (CWE-613). A successful brute force attack can bypass MFA and lead to takeover of a user's account.

Description from the CNA

The WSO2 Identity Server fails to enforce a default expiry time for SMS One-Time Passwords (OTPs) used in multi-factor authentication (MFA). This allows unused OTPs to remain valid indefinitely, presenting an opportunity for malicious actors to conduct brute force attacks by repeatedly guessing the OTP. The absence of automatic expiration for OTPs grants attackers an unlimited timeframe to attempt guessing the correct code. A successful brute force attack can lead to an MFA bypass, resulting in the unauthorized takeover of a user's account and compromising the security and privacy of both the individual and the system.
