Understanding CVE-2025-24864: Incorrect Access Permissions in RemoteView Agent
CVE-2025-24864 highlights a critical vulnerability within RSUPPORT Co., Ltd.’s RemoteView Agent (for Windows). This vulnerability exists in versions prior to 8.1.5.2 and is due to incorrect access permissions being assigned to a specific folder. As a result, a non-administrative user on the remote PC could execute arbitrary OS commands with LocalSystem privilege.
The vulnerability has been classified under CWE-276, which denotes ‘Incorrect Default Permissions’. Such permissions can lead to unauthorized activities being performed on affected systems. According to CVSS v3.0 standards, this has been given a base score of 7.8, categorizing it as a high-severity issue. The vector string details the exploit criteria: CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H. This implies that an attacker with local access, low complexity, and low privileges can exploit this flaw without user interaction, affecting confidentiality, integrity, and availability significantly.
Mitigation Strategies
Addressing CVE-2025-24864 effectively is crucial to maintaining the secure operation of systems using the affected software. Here are steps to mitigate this vulnerability:
- Immediate Update: The foremost step is to upgrade RemoteView Agent for Windows to version 8.1.5.2 or later. This version includes patches that rectify the incorrect access permission issue, thus preventing potential exploit scenarios.
- Review User Permissions: Conduct a comprehensive audit of user permissions across systems to ensure that non-administrative users do not have unnecessary access to critical folders or settings.
- Implement Least Privilege Principle: Ensure that users and applications have the minimum level of access necessary for their function. This can help mitigate the risk should other vulnerabilities arise.
- Monitor Systems: Regularly monitor system logs and access requests for unusual activity, which might indicate attempts to exploit vulnerabilities.
It is advisable for organizations using the RemoteView Agent to implement these measures promptly. Staying informed on emerging vulnerabilities and applying timely patches remains a cornerstone of robust cybersecurity practices.
