The CVE-2025-58308 vulnerability stems from an improper security criterion check within Huawei’s call module, which handles telecommunication functions. This module validates security parameters like authentication tokens or session integrity during call processing. The flaw exists in the validation logic where specific inputs, such as crafted caller IDs or protocol messages, bypass security checks due to insufficient sanitization. When a call request is received, the module fails to enforce all required security criteria under certain conditions, allowing malicious actors to trigger abnormal behavior. This occurs because the code lacks proper condition checks or has logical errors, permitting unauthorized access. Exploitation requires network access to the affected module, enabling attackers to send malicious packets that exploit the flawed criterion evaluation. This can lead to call hijacking, service disruption, or data eavesdropping by bypassing access controls. The improper check ignores key security metrics, allowing the module to proceed with processing without adequate verification, thereby compromising confidentiality, integrity, and availability. The core issue is inconsistent application of security criteria, creating an attack surface for privilege escalation or denial-of-service in call features.
