Overview
CVE-2025-58308 is a high-severity vulnerability discovered in the call module of certain Huawei products. This vulnerability stems from an improper criterion security check during the processing of call-related operations. Successful exploitation of this flaw can lead to unpredictable and abnormal behavior of features dependent on the affected call module.
Technical Details
The core issue lies within insufficient validation during the security checks within the call module. The specific details regarding the impacted Huawei products and the exploitable function calls are outlined in Huawei’s security bulletin. The lack of proper validation allows attackers to bypass intended security measures, leading to potentially unauthorized actions within the call functionality. Details about the specific attack vectors are available in the official Huawei advisory (see references below). The improper security check leaves an opening for malformed or unexpected input to be processed by the call module.
CVSS Analysis
This vulnerability has been assigned a CVSS score of 7.3, indicating a high level of severity. This score takes into account factors such as the potential for remote exploitation, the complexity of the exploit, and the impact on confidentiality, integrity, and availability. A successful exploit does not require user interaction, and exploit code is thought to be possible based on the vulnerability type.
Possible Impact
Successful exploitation of CVE-2025-58308 can result in a range of negative consequences, including:
- Abnormal Feature Performance: Core calling features might malfunction, preventing users from initiating or receiving calls.
- Denial of Service: Repeated exploitation attempts could lead to resource exhaustion and ultimately a denial-of-service condition.
- Potential for Further Exploitation: In some scenarios, successful exploitation of this vulnerability could serve as a stepping stone for more serious attacks, potentially leading to data breaches or unauthorized access to system resources.
Mitigation and Patch Steps
Huawei has released a patch to address this vulnerability. Users of affected Huawei products are strongly advised to take the following steps:
- Identify Affected Products: Consult the official Huawei security bulletin (linked below) to determine if your device is affected by CVE-2025-58308.
- Apply the Patch: Download and install the security patch provided by Huawei as soon as possible. Follow the instructions provided by Huawei for the update process.
- Monitor for Suspicious Activity: After applying the patch, closely monitor your devices for any unusual behavior that could indicate a potential security breach.
