CVE-2024-5617 WSO2 CVE debrief

Who should care

Defenders responsible for authentication mechanisms, account management, and security configurations should assess exposure and prioritize verification of current authentication mechanisms.

Why it matters

A functional flaw in the account lock feature allows brute force attacks by enabling continued authentication attempts against the primary user store account when users with identical usernames exist in both primary and secondary user stores. Defenders should prioritize verifying the existence of identical usernames across user stores and assess the effectiveness of current authentication mechanisms.

• Potential for brute force attacks against primary user store accounts
• Need for verification of identical usernames across user stores
• Potential for unauthorized access to sensitive information or accounts

Technical summary

The account lock feature fails to correctly enforce account lockouts on the primary user store when users with identical usernames exist in both primary and secondary user stores. This occurs because the lock condition is only applied to the secondary user store account in such scenarios, allowing continued authentication attempts against the primary user store account. The flaw enables brute force attacks, potentially leading to unauthorized access to sensitive information or accounts. Defenders should prioritize verifying the existence of identical usernames across user stores and assess the effectiveness of current authentication mechanisms.

Defensive priority

Defenders should prioritize verifying the existence of identical usernames across user stores and assess the effectiveness of current authentication mechanisms.

Recommended defensive actions

• Verify the existence of identical usernames across primary and secondary user stores
• Assess the effectiveness of current authentication mechanisms and account lockout policies
• Implement additional monitoring to detect potential brute force attacks
• Review compensating controls for exposed systems while remediation is scheduled and verified
• Check relevant monitoring, detection, and logs for exposed assets that need extra review
• Track exceptions, retest remediated assets, and close the item only after evidence is documented
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

The CVE record and NVD vulnerability detail page provide information on the flaw. Further verification is needed to determine the extent of affected systems and remediation efforts. The lack of identical username checks across primary and secondary user stores introduces risk. Defenders should verify current configurations and assess potential exposure.
