Overview
CVE-2025-64126 is a critical OS command injection vulnerability identified in a specific application. This vulnerability allows an unauthenticated attacker to potentially execute arbitrary commands on the affected system due to insufficient input validation. The core problem lies in the application’s failure to properly sanitize user-supplied input before using it in OS commands. This poses a significant security risk and requires immediate attention.
Technical Details
The vulnerability stems from improper input validation. Specifically, the application directly accepts a parameter from user input without verifying if it represents a valid IP address or filtering potentially malicious characters. This allows an attacker to inject arbitrary commands into the system. By crafting a malicious input string containing shell metacharacters and commands, an attacker can bypass intended security measures and execute commands with the privileges of the application. For example, an attacker might inject commands to read sensitive files, modify system configurations, or even gain complete control of the affected device.
CVSS Analysis
This vulnerability has been assigned a CVSS score of 10, indicating its critical severity. A CVSS score of 10 signifies the highest level of risk due to the ease of exploitation, the level of access an attacker can gain, and the potential impact on confidentiality, integrity, and availability.
Possible Impact
The exploitation of CVE-2025-64126 can have severe consequences, including:
- Complete System Compromise: An attacker can gain complete control of the affected system.
- Data Breach: Sensitive data can be accessed, modified, or stolen.
- Denial of Service (DoS): The system can be rendered unavailable to legitimate users.
- Malware Installation: The attacker can install malware, backdoors, or other malicious software.
- Lateral Movement: Attackers can leverage compromised systems to gain access to other systems within the network.
Mitigation and Patch Steps
To mitigate the risk posed by CVE-2025-64126, the following steps are recommended:
- Apply the Patch: Immediately apply the security patch released by the vendor. Check the vendor’s security advisories for specific instructions.
- Input Validation: Implement robust input validation and sanitization techniques to prevent command injection. Specifically, validate that the input conforms to the expected format (e.g., a valid IP address) and filter out any potentially malicious characters or sequences.
- Least Privilege: Ensure that the application runs with the minimum necessary privileges.
- Web Application Firewall (WAF): Deploy a WAF to detect and block malicious requests.
- Network Segmentation: Isolate vulnerable systems within a segmented network to limit the potential impact of a successful attack.
- Monitor Logs: Continuously monitor system logs for suspicious activity.
