Landray Office Automation Treexml.tmpl Remote Code Execution Scanner

Landray Office Automation (OA) is a comprehensive enterprise management platform used globally by organizations to enhance their workflow efficiency and document management processes. The platform integrates multiple functionalities, including communication, collaborative management, and knowledge sharing, tailored to meet the diverse needs of businesses of varying sizes. This software is primarily utilized by businesses seeking to streamline operations and improve information dissemination across departments. It serves not just as a tool for managing routines but also as a strategic asset that facilitates decision-making and resource allocation. Due to its extensive use in handling sensitive and critical business data, maintaining its security is paramount. Ensuring that Landray OA operates free of vulnerabilities helps protect organizational IT infrastructure against potential threats.

The Remote Code Execution (RCE) vulnerability allows attackers to execute arbitrary commands or code on a remote system. This type of vulnerability poses serious security threats since it enables unauthorized access and manipulation of affected systems. Typically, RCE vulnerabilities arise from improper input validation, allowing crafted payloads to bypass security checks. Attackers can exploit this vulnerability to gain control over the server, potentially leading to data theft, unauthorized modifications, or even system shutdowns. Identifying and addressing RCE vulnerabilities in critical systems is essential to safeguard against exploitation activities. RCE vulnerabilities underscore the importance of robust security practices and regular system updates.

In this scanner, the technical detection involves sending a crafted request containing a malicious script to a target endpoint within the Landray Office Automation system. The vulnerable endpoint is identified as the 'treexml.tmpl' file, where the 'script' parameter is manipulated to inject executable code such as a ping command. This command attempts to reach an interactsh server to confirm the vulnerability's presence by checking for DNS requests. Successful exploitation is determined by evaluating response body conditions and server responses, which help verify the vulnerability's existence and potential exploitability. The provided templates demonstrate these key response features, simulating network conditions that an attacker might exploit.

Exploiting the Remote Code Execution vulnerability can lead to severe repercussions. Attackers could gain unauthorized access to the server, escalate privileges, and control critical system operations. This breach might allow them to exfiltrate sensitive organizational data, modify essential files, or introduce malicious software into the network. Additionally, leveraging this vulnerability can serve as a foundation for launching broader cyberattacks, potentially affecting not only the targeted system but also related networks and stakeholders. The impacted organization's reputation, financial stability, and operational efficiency could be substantially compromised by such an event.
