Lifecycle Timeline
3Description
OPEXUS eComplaint and eCASE before version 10.1.0.0 include the secret verification code in the HTTP response when requesting a password reset via 'ForcePasswordReset.aspx'. An attacker who knows an existing user's email address can reset the user's password and security questions. Existing security questions are not asked during the process.
Analysis
A critical authentication bypass vulnerability in OPEXUS eComplaint and eCASE applications allows unauthenticated attackers to take over any user account by exploiting improper exposure of password reset verification codes in HTTP responses. The vulnerability affects all versions before 10.1.0.0 and enables attackers who know a user's email address to reset passwords and security questions without any verification, granting full account access. …

Remediation
Within 24 hours: Identify all OPEXUS eComplaint and eCASE instances in production and verify version numbers; disable the ForcePasswordReset.aspx functionality if operationally feasible or restrict access to trusted networks only. Within 7 days: Implement WAF rules to block or rate-limit password reset requests, monitor authentication logs for suspicious password reset activity, and notify users to change passwords if they have not done so recently. …
