Sangfor EDR Remote Code Execution Scanner

Sangfor EDR is a comprehensive endpoint detection and response solution widely used in enterprise environments to enhance cybersecurity measures. Primarily deployed by IT departments, it is designed to identify, investigate, and respond to threats across diverse computer networks. The software assists organizations in meeting compliance requirements, reducing exposure to threats, and combating advanced persistent threats. IT administrators frequently leverage Sangfor EDR to streamline their security operations and correlate threat intelligence. It integrates with various security platforms to provide a centralized management system for threat detection and response. As a critical infrastructure component, Sangfor EDR plays a significant role in maintaining the cybersecurity posture of businesses.

This scanner targets a critical vulnerability, Remote Code Execution (RCE), which is prevalent in certain versions of Sangfor EDR. RCE vulnerabilities allow attackers to execute arbitrary code on a remote system, potentially leading to unauthorized access and control. The exploitation of this vulnerability requires neither authentication nor advanced execution conditions, making it a substantial threat. By exploiting this vulnerability, attackers can perform actions at the privilege level of the application. The threat landscape is further exacerbated by the potential for network-wide impact if the vulnerability is leveraged. Such vulnerabilities are highly sought after in malicious campaigns due to their potential severity.

The scanner identifies vulnerable endpoints by sending crafted payloads to the /api/edr/sangforinter/v2/cssp/slog_client endpoint. It utilizes a POST request with specifically formatted parameters to simulate a command execution scenario; this is intended to trigger responses indicative of the exploitation of the RCE. Technical details including HTTP status and specific strings within server responses are examined to determine the presence of the vulnerability. Successful detection is contingent upon matching certain regular expressions and HTTP response statuses that signify access to system files. The payload execution simulates an attack scenario by manipulating parameters to bypass security measures within the application's API.

If this vulnerability is exploited, the consequences can be severe. Attackers could gain unauthorized access to sensitive data, manipulate system resources, and disrupt normal operations. In the worst-case scenario, malicious users could establish persistent access, install backdoors, and execute further attacks across the network. Organizations may face significant data breaches, service interruptions, and financial losses due to the exploitation of such vulnerabilities. The exploitation might also lead to a loss in consumer trust and have long-lasting impacts on an organization's reputation. Additionally, regulatory and legal consequences might follow if compliance is breached due to unauthorized data exposure.
