Sangfor Log Center Remote Code Execution Scanner

Sangfor Log Center is a comprehensive log management solution that is utilized across various industries to manage and analyze logs systematically. It is commonly used by IT administrators for monitoring network activities, preventing data breaches, and ensuring regulatory compliance. This software, developed by Sangfor Technologies, is deployed in enterprise environments where efficient log handling is critical. It serves businesses in sectors such as finance, healthcare, and information technology. Its ability to streamline log data management helps organizations maintain security and operational efficiency. Users rely on it for real-time log insights and threat detection capabilities.

The vulnerability exploited in this context is known as Remote Code Execution (RCE). In RCE vulnerabilities, an attacker can execute arbitrary commands or code on a remote system. This type of vulnerability is critical because it allows attackers to take full control of the vulnerable system. RCE vulnerabilities can be exploited through web applications with insufficient input validation. Such vulnerabilities pose a significant risk as they can lead to unauthorized access and data compromise. Detection of RCE vulnerabilities is crucial for maintaining the security integrity of systems.

The technical details regarding this vulnerability involve manipulation of specific web endpoints where input is not adequately sanitized. In the case of Sangfor Log Center, the endpoint `c.php` is vulnerable to system commands passed through the `strip_slashes` parameter. The vulnerability is triggered when malicious input is crafted for this endpoint, which is then executed by the server hosting the application. Command Injection through such endpoints allows attackers to leverage the underlying system’s capabilities remotely. This vulnerability emphasizes the importance of input validation and proper patch management.

When exploited, this RCE vulnerability can have severe consequences for the affected network infrastructure. An attacker could gain unauthorized access to sensitive data or disrupt the normal operations of the system. Potential outcomes include a complete takeover of the compromised server, installation of malware or backdoors, and exfiltration of sensitive data. Such attacks can lead to reputational damage, legal consequences, and significant financial losses for the organization. The ability to execute remote commands as an attacker fundamentally undermines the security posture of affected systems.
