Overview
CVE-2025-66314 is a high-severity vulnerability affecting ZTE ElasticNet UME R32, specifically version ElasticNet_UME_R32_V16.23.20.04. This vulnerability stems from improper privilege management, allowing attackers to access functionality that is not adequately constrained by Access Control Lists (ACLs). This can lead to unauthorized actions and potential compromise of the system.
Technical Details
The vulnerability resides in the way ZTE ElasticNet UME R32 handles user privileges. Due to insufficient ACL enforcement, an attacker with low-level access may be able to exploit specific functionalities and gain access to higher-level operations or sensitive data. The flaw allows bypassing intended security restrictions and performing actions reserved for administrators or other privileged users. The root cause is likely a flaw in the privilege checking logic within the affected software component.
CVSS Analysis
- CVSS Score: 7.5 (HIGH)
- The high CVSS score indicates the severity of the vulnerability and the potential for significant impact. A score of 7.5 suggests that the vulnerability can be exploited remotely with relatively low skill, and can result in substantial data compromise and system disruption.
Possible Impact
Successful exploitation of CVE-2025-66314 can have significant consequences, including:
- Data Breach: Unauthorized access to sensitive data managed by ZTE ElasticNet UME R32.
- System Compromise: Gaining control over critical system functions, potentially leading to denial-of-service or complete system takeover.
- Configuration Changes: Modifying system configurations without proper authorization, disrupting network operations.
- Lateral Movement: Using the compromised system as a stepping stone to attack other systems within the network.
Mitigation or Patch Steps
The recommended mitigation for CVE-2025-66314 is to apply the patch provided by ZTE. It is strongly advised to upgrade to the latest version of ElasticNet UME R32 that addresses this vulnerability. Contact ZTE support for the specific patch or updated version.
- Identify Affected Systems: Determine all instances of ZTE ElasticNet UME R32 running version ElasticNet_UME_R32_V16.23.20.04.
- Apply the Patch: Download and install the official patch from ZTE as soon as it becomes available.
- Verify Installation: Confirm that the patch has been successfully applied and that the vulnerability is no longer present.
- Monitor Systems: Continue to monitor systems for any signs of suspicious activity.
- Review ACL Configuration: Review the ACL configurations within the system to verify if there were any unintended permission settings, even after patching.
