The vulnerability identified as CVE-2019-15091 resides within the filemgr.php component of Artica Integria IMS version 5.0.86, representing a critical arbitrary file upload flaw that enables remote attackers to execute malicious code on affected systems. This vulnerability specifically manifests through the index.php endpoint with parameters sec=wiki&sec2=operation/wiki/wiki&action=upload, which lacks proper input validation and file type restrictions. The flaw falls under the category of CWE-434, which describes a scenario where applications allow file uploads without adequate security controls, creating a pathway for attackers to bypass security measures and deploy malicious payloads.
The technical implementation of this vulnerability exploits the absence of proper file validation mechanisms within the file upload functionality. Attackers can manipulate the upload process to submit executable files or scripts that will be stored and potentially executed within the web application's directory structure. This vulnerability represents a direct violation of secure coding practices and demonstrates inadequate defense-in-depth measures within the application's security architecture. The flaw enables attackers to gain persistent access to the system and potentially escalate privileges through the execution of malicious code.
Operationally, this vulnerability poses significant risks to organizations using Artica Integria IMS 5.0.86, as it provides a straightforward attack vector for remote code execution. The impact extends beyond simple file uploads to encompass potential system compromise, data exfiltration, and service disruption. Attackers can leverage this vulnerability to deploy web shells, backdoors, or other malicious payloads that maintain persistence within the compromised environment. The vulnerability's exploitation does not require authentication, making it particularly dangerous as it can be exploited by any remote attacker without prior access credentials.
Security professionals should consider this vulnerability in the context of the ATT&CK framework, particularly under the T1190 technique for Exploit Public-Facing Application, and T1059 for Command and Scripting Interpreter. Organizations should implement immediate mitigations including restricting file upload functionality, implementing strict file type validation, and employing proper access controls for the affected endpoints. The vulnerability highlights the importance of input sanitization, proper file validation, and the implementation of secure file handling practices as outlined in OWASP Top 10 and NIST cybersecurity guidelines. Patch management should be prioritized to address this vulnerability, as it represents a critical security weakness that can lead to complete system compromise.
