CVE-2018-10642 in iTop
Summary
by MITRE
Command injection vulnerability in Combodo iTop 2.4.1 allows remote authenticated administrators to execute arbitrary commands by changing the platform configuration, because web/env-production/itop-config/config.php contains a function called TestConfig() that calls the vulnerable function eval().

The vulnerability CVE-2018-10642 represents a critical command injection flaw in Combodo iTop version 2.4.1 that specifically targets authenticated administrative users. This vulnerability resides within the platform's configuration management system where the TestConfig() function directly invokes the dangerous eval() function, creating an exploitable path for remote command execution. The flaw demonstrates a fundamental security oversight in input validation and code execution handling within the application's core configuration components.
The technical implementation of this vulnerability stems from the insecure use of the eval() function within the web/env-production/itop-config/config.php file. When administrators modify platform configuration settings through the web interface, the system processes these changes through the TestConfig() function which then passes user-controllable input directly to eval() without proper sanitization or validation. This creates a classic command injection scenario where malicious commands embedded within configuration parameters are executed with the privileges of the web application process. The vulnerability is particularly dangerous because it requires only authenticated administrative access, which is often a privileged position within enterprise environments.
From an operational impact perspective, this vulnerability enables attackers who have gained administrative credentials to execute arbitrary commands on the affected server, potentially leading to complete system compromise. The attacker can leverage this to escalate privileges, access sensitive data, install backdoors, or pivot to other systems within the network. The vulnerability affects organizations using Combodo iTop 2.4.1 as a core IT service management platform, where the application typically runs with elevated system privileges and may have access to critical infrastructure components. This represents a significant risk to enterprise security posture and compliance requirements.
Organizations should immediately apply the vendor-provided patch for Combodo iTop 2.4.1 to remediate this vulnerability, as the fix involves removing the dangerous eval() call and implementing proper input validation for configuration parameters. Additional mitigations include implementing network segmentation to limit administrative access, enforcing strict access controls for administrative accounts, and monitoring for unusual configuration changes. This vulnerability aligns with CWE-94, which addresses "Improper Control of Generation of Code ('Code Injection')", and maps to ATT&CK technique T1059.001 for command and scripting interpreter. Organizations should also consider implementing web application firewalls and regular security assessments to detect similar insecure coding practices in their application environments.
