CVE-2024-6832 WSO2 CVE debrief

Who should care

Security teams and administrators responsible for user account management and authentication mechanisms should be aware of this vulnerability and take steps to mitigate the risk of brute force attacks. This includes reviewing and updating account locking configurations, implementing compensating controls, and monitoring authentication attempts. Additionally, security teams should verify vendor remediation status and conduct inventory checks for affected systems. Affected operators and platforms should prioritize patching and vulnerability management. Security teams should also review compensating controls for exposed systems while remediation is scheduled and verified.

Technical summary

The account locking mechanism fails to trigger when secondary user stores are inaccessible, allowing repeated authentication attempts with invalid credentials. This occurs because the software does not maintain a consistent state for account locking if it cannot reach all configured user stores. As a result, users in accessible user stores are left vulnerable to brute force attacks. A malicious actor can exploit this by attempting numerous invalid password combinations against a user account without the expected account lockout consequence.

Defensive priority

Medium priority due to potential for brute force attacks

Recommended defensive actions

• Review and update account locking configurations
• Implement compensating controls for brute force attacks
• Monitor authentication attempts for suspicious activity
• Verify vendor remediation status
• Conduct inventory checks for affected systems
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up.
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.

Evidence notes

The CVE record and NVD detail provide information on the vulnerability. The WSO2 security advisory may offer additional context.
