This vulnerability arises because there are no limitations on the number of authentication attempts a user can make. An attacker can exploit this weakness by continuously sending authentication requests, leading to a denial-of-service (DoS) condition. This can overwhelm the authentication system, rendering it unavailable to legitimate users and potentially causing service disruption. This can also allow attackers to conduct brute-force attacks to gain unauthorized access.
Conclusion & alert: CVE-2025-53968 is rated Moderate Risk (40.5/100): CVSS High severity, with low exploitation likelihood (EPSS 0.38%). Mandatory action: Review affected assets and schedule remediation.
