LotApp Remote Code Execution Scanner

The LotApp Application Delivery System is a software platform designed to facilitate the efficient delivery of applications across various network environments. It is used by enterprises and network administrators to manage, distribute, and optimize application performance effectively. The platform supports a range of application delivery services, including load balancing, acceleration, and security, ensuring seamless application experience for end-users. LotApp is commonly deployed in environments where high availability and application performance are critical. Organizations rely on it to manage traffic, optimize application delivery, and provide robust security features for their applications. Its versatility and features make it a widely adopted solution for enterprises looking to enhance their application delivery strategies.

The Remote Code Execution (RCE) vulnerability in the LotApp Application Delivery System allows unauthorized users to execute arbitrary code on the targeted system. This vulnerability is often exploited by sending malicious requests that trigger code execution on the server. It represents a significant security risk, as it can be used to gain control over the affected system, leading to data theft, system compromise, or service disruption. RCE vulnerabilities are attractive targets for attackers due to the potential for high impact and widespread exploitation. Identifying and mitigating such vulnerabilities is crucial to maintaining the security and integrity of sensitive systems. The LotApp RCE vulnerability underscores the importance of regular security assessments and updates in software applications.

The vulnerability is identified in the endpoint "/acc/debug/bytecache_run_action.php" of the LotApp Application Delivery System. It is triggered by a vulnerable parameter 'engine', which improperly handles user input, leading to the execution of arbitrary commands. The request manipulates the 'action' parameter to introduce a shell command that writes to a file, demonstrating command execution capability. Upon successful exploitation, the malicious command writes a unique identifier to a "1.txt" file within the server, confirming the breach. This vulnerability arises from insufficient input validation and command sanitization, making it susceptible to exploitation. A malicious actor could leverage this flaw to execute unauthorized commands, potentially leading to system compromise and data exfiltration.

The potential effects of exploiting a Remote Code Execution (RCE) vulnerability in LotApp include unauthorized access to sensitive data, complete control over the application delivery system, and further exploitation of connected networks. Attackers may insert backdoors or malware, facilitating long-term access and repeated breaches. Critical data could be extracted, modified, or deleted, causing operational disruptions or financial loss. There is also a risk of lateral movement within the network, accessing other systems and applications through the compromised LotApp server. Successful exploitation of the RCE vulnerability poses a considerable threat to organizational security, emphasizing the need for immediate remediation and continuous security monitoring.
