The CVE-2017-16000 vulnerability represents a critical sql injection flaw within the EyesOfNetwork web interface version 5.1-0, specifically targeting the eonweb component. This vulnerability affects remote authenticated administrators who possess valid credentials to access the system, making it particularly dangerous as it leverages legitimate user privileges to escalate attacks. The vulnerability resides in the module/capacity_per_label/index.php file where the graph parameter is processed without adequate input sanitization or validation mechanisms.
The technical implementation of this vulnerability stems from improper parameter handling within the web application's input processing pipeline. When an authenticated administrator accesses the capacity_per_label module and provides a malicious graph parameter, the application fails to properly escape or validate the input before incorporating it into sql queries. This lack of input sanitization creates an exploitable condition where attacker-controlled data can be interpreted as sql commands rather than simple data values. The vulnerability aligns with CWE-89 which specifically addresses sql injection flaws where untrusted data is directly incorporated into sql command strings without proper escaping or parameterization.
The operational impact of this vulnerability extends beyond simple data exfiltration, as it provides attackers with the capability to execute arbitrary sql commands on the underlying database system. This could enable full database compromise, allowing attackers to read sensitive information, modify or delete data, create new database users, or even escalate privileges to gain access to underlying system resources. The vulnerability affects the integrity and confidentiality of the entire EyesOfNetwork monitoring platform, potentially exposing critical network monitoring data and system configurations to unauthorized access.
From a threat modeling perspective, this vulnerability demonstrates a classic privilege escalation scenario where authenticated users can leverage their legitimate access to perform malicious activities. The ATT&CK framework would classify this under T1078 Valid Accounts and T1046 Network Service Scanning, as attackers could use this vulnerability to explore database structures and potentially move laterally within the network. The vulnerability also relates to T1005 Data from Local System and T1021 Remote Services, as it allows for data extraction and potential remote access through database manipulation.
Mitigation strategies should focus on implementing proper input validation and parameterized queries throughout the application codebase. The most effective immediate fix involves applying parameterized queries or prepared statements to all sql operations, ensuring that user-supplied parameters are treated as data rather than executable code. Additionally, implementing proper input sanitization measures, including whitelisting acceptable parameter values and implementing comprehensive output encoding, would significantly reduce the attack surface. Organizations should also consider implementing web application firewalls and input validation rules to detect and block malicious payloads before they reach the vulnerable application components. Regular security code reviews and penetration testing should be conducted to identify and remediate similar vulnerabilities across the entire application stack, ensuring compliance with security standards such as those outlined in the OWASP Top Ten and NIST cybersecurity frameworks.
