The vulnerability identified as CVE-2025-71284 affects Synway SMG Gateway Management Software, specifically in the RADIUS configuration endpoint located at /en/9-2radius.php. This vulnerability allows attackers to exploit the application through OS command injection due to a lack of sanitization on the radius_address POST parameter. By crafting a POST request with specific parameters, an unauthenticated remote attacker can inject arbitrary shell commands, leading to potential remote code execution.
This vulnerability has been assigned a CVSS score of 9.3, categorizing it as critical. The implications of a successful exploit are severe, as attackers may gain unauthorized access to systems, potentially compromising confidentiality, integrity, and availability. Given the critical nature of this vulnerability, organizations using the affected software must prioritize remediation.
Exploitation evidence was first observed by the Shadowserver Foundation on July 11, 2025. Organizations are advised to assess their exposure and apply necessary patches or mitigations as soon as possible. Failure to address this vulnerability could result in significant operational disruptions and data breaches.
Organizations should prioritize patching immediately.
Vulnerability Details
The OS command injection vulnerability in Synway SMG Gateway Management Software is caused by improper handling of user input in the RADIUS configuration endpoint. The CVE description highlights that the radius_address POST parameter is directly interpolated into a sed command without proper validation or sanitization, allowing attackers to craft malicious requests that can execute arbitrary commands.
The vulnerability is classified under CWE-78, which pertains to OS command injection vulnerabilities. The CVSS score of 9.3 reflects the critical severity of this issue, emphasizing the high potential impact on confidentiality, integrity, and availability. Organizations should take this matter seriously and ensure they are utilizing the latest patched version of the software.
Technical Analysis
The root cause of the vulnerability lies in the lack of input sanitization for the radius_address parameter. When user inputs are not properly validated, attackers can manipulate the input to include shell commands. The attack vector is network-based, allowing remote attackers to exploit the vulnerability without needing physical access to the system.
The attack complexity is low, and no privileges are required to exploit this vulnerability, making it accessible to a wide range of attackers. Additionally, user interaction is not required, further increasing the risk. The impact on confidentiality, integrity, and availability is high, as successful exploitation could allow attackers to execute arbitrary commands on the server.
Risk & Impact Analysis
The risk to organizations includes unauthorized access and control over affected systems, which could lead to data breaches and operational disruptions. The potential blast radius is significant, considering the critical nature of the software utilized in network management. Organizations must understand that the exploitation of this vulnerability could result in severe consequences, including loss of sensitive data and reputational damage.
Given the CVSS score of 9.3, organizations should address this vulnerability in their priority patch cycle. The urgency for remediation cannot be overstated, and it is essential for organizations to implement robust security measures to protect their systems from such vulnerabilities.
