Panabit iXCache Remote Code Execution Scanner

Panabit iXCache is widely used in network systems to enhance caching efficiencies and manage internet traffic effectively. It is typically employed by large enterprises and network providers to optimize speed and reduce latency. The product is purpose-built for quick adaptation within complex network architectures, ensuring minimal disruptions. It offers various modules for flexible control, accommodating specific networking needs. Due to its role in controlling significant internet traffic flow, any vulnerabilities can have far-reaching consequences. Network administrators deploy it to safeguard and optimize traffic routing and caching operations.

The vulnerability identified in Panabit iXCache is a Remote Code Execution (RCE) flaw, which poses severe security risks. An RCE vulnerability allows attackers to execute arbitrary code on a server or device remotely, often leading to full system compromise. This specific flaw occurs within the date_config module due to improper command input handling. Command execution vulnerabilities like these enable attackers to gain control over system functionalities, leading to potential service disruption. This serious flaw emphasizes the need for persistent monitoring and patching. The presence of such vulnerabilities underlines the crucial nature of ensuring network services that expose web interfaces are protected and up-to-date.

The technical root cause of this vulnerability is command splicing within the date_config module. It leverages the input parameter, ntpserver, merging malicious commands with expected input. Attackers can exploit this by sending crafted requests that include commands to be executed in the backend. The vulnerability primarily resides in the lack of sanitization of user inputs, allowing unintended command execution during normal operation. Subsequent rogue commands are executed with the authority level of the application, thus broadening the potential impact. The vulnerability is exploitable through crafted HTTP POST requests targeting specific endpoints. Effective remediation requires comprehensive review and correction of input validation procedures.

Exploitation of this vulnerability can lead to unauthorized control of affected systems. Attackers may use it to deploy malicious code, leading to data breaches or disruption of services. Additionally, it presents potential avenues for introducing malware or stealing sensitive information handled by the systems. System performance can be degraded by unauthorized processes consuming resources. Targeted businesses might encounter reputational damage or financial losses if data theft occurs. If left unchecked, this vulnerability can serve as a foothold for further intrusions into the network.
