The vulnerability identified as CVE-2017-20007 affects Ingeteam INGEPAC DA AU AUC_1.13.0.28 and earlier versions of their web application interface. This security flaw represents a critical information disclosure vulnerability that exposes sensitive configuration data to unauthenticated remote attackers who can access the device's web service. The vulnerability stems from improper access controls within the web application's path structure, allowing unauthorized users to navigate to directories containing critical system configuration files. Such exposure creates a significant risk for attackers seeking to escalate their privileges and execute more sophisticated attacks against the affected device.
The technical implementation of this vulnerability involves a lack of proper authentication and authorization checks within the web application's directory traversal mechanisms. Attackers can exploit this weakness by simply accessing specific URL paths that are not properly secured, thereby gaining access to configuration files that contain sensitive operational data. This type of vulnerability is classified under CWE-200, which deals with information exposure, and represents a fundamental breakdown in the principle of least privilege. The web application's failure to implement proper access controls for sensitive paths creates an attack surface that directly violates security best practices and industry standards.
The operational impact of this vulnerability extends beyond simple information disclosure, as the exposed configuration files often contain critical system parameters that could be leveraged for further exploitation. Attackers can use the retrieved configuration data to understand the device's operational parameters, network configurations, and potentially identify other vulnerabilities within the system. This information disclosure creates a foundation for more advanced attacks, including but not limited to privilege escalation, lateral movement within network segments, and targeted exploitation of other system components. The vulnerability directly aligns with ATT&CK technique T1083, which covers directory and file discovery, and T1566, which deals with credential access through social engineering or system compromise.
Organizations utilizing Ingeteam INGEPAC DA AU AUC_1.13.0.28 or earlier versions should immediately implement mitigations to address this vulnerability. The primary recommendation involves implementing proper access controls and authentication mechanisms for all web application paths, ensuring that sensitive directories are protected from unauthorized access. Network segmentation and firewall rules should be configured to restrict access to the device's web service to trusted network segments only. Additionally, regular security audits and vulnerability assessments should be conducted to identify similar access control weaknesses in other system components. The affected devices should be updated to the latest firmware version that addresses this information disclosure vulnerability, as Ingeteam has likely released patches to resolve this specific security flaw. System administrators should also monitor network traffic for suspicious access patterns to the web application and implement intrusion detection systems to identify potential exploitation attempts.
