Summary
by MITRE • 07/31/2025
A command injection vulnerability exists in GestioIP 3.0 commit ac67be and earlier in ip_checkhost.cgi. Crafted input to the 'ip' parameter allows attackers to execute arbitrary shell commands on the server via embedded base64-encoded payloads. Authentication may be required depending on deployment configuration.

The command injection vulnerability identified as CVE-2013-10039 affects GestioIP version 3.0 and earlier, specifically within the ip_checkhost.cgi component. This flaw represents a critical security weakness that allows remote attackers to execute arbitrary shell commands on the affected server. The vulnerability stems from insufficient input validation and sanitization in the handling of the 'ip' parameter, which is processed without proper escaping or encoding mechanisms. The attack vector involves embedding base64-encoded payloads within the ip parameter, which are then decoded and executed by the server's shell, effectively bypassing normal security controls and access restrictions.
This vulnerability aligns with CWE-77, which categorizes command injection flaws as weaknesses where untrusted input is directly incorporated into shell commands without proper sanitization. The technical implementation of this flaw demonstrates how attackers can leverage the base64 encoding mechanism to obfuscate malicious payloads, making detection more challenging while maintaining execution effectiveness. The vulnerability operates at the application layer and can be exploited through web-based interfaces, potentially affecting any system running GestioIP 3.0 or earlier versions where the ip_checkhost.cgi script is accessible. The security implications extend beyond simple command execution to include potential privilege escalation, data exfiltration, and system compromise depending on the execution context and permissions of the affected service account.
The operational impact of this vulnerability is severe and multifaceted, as it enables attackers to gain complete control over the affected server. Once exploited, adversaries can execute arbitrary code with the privileges of the web server process, potentially leading to full system compromise. The vulnerability may be leveraged to establish persistent backdoors, extract sensitive configuration data, modify network configurations, or use the compromised system as a launch point for further attacks within the network infrastructure. Depending on the deployment configuration, authentication requirements may limit initial access, but successful exploitation can result in unauthorized privilege escalation and complete system takeover. The vulnerability affects network infrastructure management systems and could potentially impact network monitoring, configuration management, and device discovery functions that rely on the vulnerable component.
Mitigation strategies for CVE-2013-10039 should prioritize immediate remediation through official vendor updates and patches. Organizations should implement input validation and sanitization measures that prevent the execution of shell commands based on user-supplied data. The implementation of proper parameter escaping and encoding techniques, combined with input whitelisting for critical parameters, can effectively prevent exploitation attempts. Network segmentation and access control measures should be strengthened to limit exposure of vulnerable components to untrusted networks. Security monitoring should include detection of suspicious base64-encoded patterns in web requests and anomalous command execution patterns. Additionally, implementing web application firewalls and input validation rules specifically targeting command injection attempts can provide defense-in-depth measures. Regular security assessments and vulnerability scanning should be conducted to identify similar weaknesses in other network management applications and ensure comprehensive protection against similar attack vectors. The ATT&CK framework categorizes this vulnerability under T1059.001 for command and scripting interpreter and T1068 for exploit for privilege escalation, highlighting the multi-stage nature of potential exploitation and the need for comprehensive security controls.
