This vulnerability exists within the UTT HiPER 520 1.7.7-160105 web management interface where a command injection flaw has been identified in the sub_44D264 function of the /goform/formPdbUpConfig file. The specific weakness occurs when processing the policyNames argument which is susceptible to manipulation by remote attackers. This represents a critical security flaw that allows unauthorized users to execute arbitrary operating system commands on the affected device. The vulnerability stems from inadequate input validation and sanitization within the web interface component, creating an attack vector that can be exploited without authentication requirements.
The technical implementation of this vulnerability aligns with CWE-78 which describes improper neutralization of special elements used in OS commands. Attackers can leverage this weakness by crafting malicious payloads containing OS command injection sequences that are then processed through the policyNames parameter. The exploitation occurs during the handling of configuration updates within the web management interface, where user-supplied input directly influences system command execution. This type of vulnerability typically arises from insufficient sanitization of user inputs before incorporating them into shell commands or system calls.
The operational impact of this vulnerability is severe as it provides remote attackers with complete control over the affected device's operating system. Successful exploitation enables attackers to execute arbitrary commands with the privileges of the web server process, potentially leading to full system compromise. This includes capabilities such as data exfiltration, installation of malware, modification of system configurations, and creation of persistent backdoors. The vulnerability affects the device's web management interface specifically, making it accessible over network connections and allowing exploitation from any remote location without requiring physical access or prior authentication.
Security mitigations for this vulnerability should focus on implementing proper input validation and sanitization measures within the web application code. The system should employ strict parameter validation to reject malicious payloads containing special characters that could be used for command injection attacks. Input filtering should be implemented at multiple layers including the web interface, application logic, and potentially at the network level through firewalls or intrusion prevention systems. Additionally, the principle of least privilege should be enforced by running web server processes with minimal necessary permissions and implementing proper access controls to restrict unauthorized remote access to management interfaces. Organizations should also consider deploying web application firewalls to monitor and block suspicious command injection patterns.
This vulnerability demonstrates the importance of secure coding practices in web applications and aligns with ATT&CK techniques such as T1059 for command and scripting interpreter and T1211 for exploitation for privilege escalation. The public disclosure of exploit code increases the risk level significantly, as it provides attackers with readily available tools to compromise affected systems. Network segmentation and monitoring should be implemented to detect potential exploitation attempts, while regular security updates and patches should be applied to address known vulnerabilities in network management interfaces. The incident highlights the critical need for comprehensive security testing including dynamic application security testing and secure code reviews to identify and remediate similar injection vulnerabilities before they can be exploited by malicious actors.
