Overview
CVE-2025-64315 is a medium severity configuration defect vulnerability identified in the file management module of certain Huawei devices. This flaw could allow a malicious actor to compromise the confidentiality and integrity of application data. This vulnerability was published on 2025-11-28.
Technical Details
The vulnerability stems from an improperly configured access control mechanism within the file management module. Specifically, insufficient validation of user-provided input allows for unauthorized modification or access to sensitive file system locations. This could potentially be exploited to overwrite configuration files, inject malicious code, or exfiltrate confidential data.
CVSS Analysis
The Common Vulnerability Scoring System (CVSS) assigned a score of 4.4 to CVE-2025-64315. This score reflects the following characteristics:
- Severity: MEDIUM
- Attack Vector: Local
- Attack Complexity: Low
- Privileges Required: High
- User Interaction: None
- Scope: Unchanged
- Confidentiality Impact: Low
- Integrity Impact: Low
- Availability Impact: None
While the impact on confidentiality and integrity is relatively low, the ease of exploitation (low attack complexity) warrants immediate attention, particularly for systems handling sensitive data.
Possible Impact
Successful exploitation of CVE-2025-64315 could lead to the following consequences:
- Data Breach: Unauthorized access to and potential exfiltration of sensitive application data.
- Data Corruption: Malicious modification of application configuration files, leading to application malfunction or denial of service.
- Privilege Escalation (Indirectly): While not a direct privilege escalation vulnerability, compromising configuration files could potentially lead to further exploitation and privilege escalation in other areas of the system.
