CVE-2024-2323 WSO2 CVE debrief

Who should care

Defenders responsible for managing user accounts and password policies should assess exposure and implement compensating controls to restrict password guessing attempts. This includes reviewing password policies, verifying the use of the RemoteUserStoreManagerService, and implementing rate limiting or IP blocking to prevent brute-force attacks. Additionally, defenders should monitor for suspicious activity and implement exception tracking to detect to

Why it matters

CVE-2024-2323 allows an attacker to repeatedly attempt password guesses for a user account without being adequately restricted when the password history validation feature is enabled, potentially leading to account impersonation.

• An attacker may attempt to discover a user's password through brute force, leading to account impersonation.
• The success rate of such an attack is influenced by the complexity of the targeted user's password, with simpler passwords increasing the likelihood of compromise.
• Defenders should verify exposure and implement compensating controls to restrict password guessing attempts.
• Remediation priority is influenced by the use of the password history validation feature and the complexity of user passwords.

Technical summary

The RemoteUserStoreManagerService does not sufficiently validate password change attempts when the password history validation feature is enabled. This allows an attacker to repeatedly attempt password guesses for a user account without being adequately restricted. The vulnerability can lead to account impersonation if the attacker is able to guess the user's password. The success rate of such an attack is influenced by the complexity of the targeted user's password, with simpler passwords increasing the likelihood of compromise.

Defensive priority

Defenders should prioritize verifying exposure and implementing compensating controls to restrict password guessing attempts.

Recommended defensive actions

• Verify exposure by checking if the RemoteUserStoreManagerService is enabled and if the password history validation feature is in use.
• Implement compensating controls to restrict password guessing attempts, such as rate limiting or IP blocking.
• Monitor for suspicious activity and implement exception tracking to detect potential attacks.
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance.
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed.
• 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.

Evidence notes

The CVE record and NVD entry provide limited information about the vulnerability and its impact. Further verification is required to determine the affected versions and remediation. The CVE Program record and NVD detail page offer source-provided CVE metadata and vulnerability assessment. However, additional review is needed to understand the full scope of the vulnerability and to identify potential mitigations. The information available suggests that defenders should verify exposure and implement compensating controls to restrict to
