Official Description

Synway SMG Gateway Management Software contains an OS command injection vulnerability in the RADIUS configuration endpoint at /en/9-2radius.php where the radius_address POST parameter is split and interpolated directly into a sed command without sanitization. An unauthenticated remote attacker can inject arbitrary shell commands by submitting a POST request with crafted radius_address, radius_address2, shared_secret2, source_ip, timeout, or retry parameters along with save=1 and enable_radius=1 to achieve remote code execution. Exploitation evidence was first observed by the Shadowserver Foundation on 2025-07-11 (UTC).

Risk Analysis

Synway SMG Gateway Management Software has a critical OS command injection vulnerability in its RADIUS configuration endpoint. An unauthenticated remote attacker can inject arbitrary shell commands by crafting POST requests, leading to remote code execution. With a CVSS score of 9.8, this is a severe vulnerability, and its presence in the KEV catalog confirms active exploitation.

Active exploitation of this vulnerability has been observed in the wild. The flaw is remotely exploitable without authentication, allowing for arbitrary shell command injection and remote code execution.

Recommended Action

Apply the necessary security updates or patches for Synway SMG Gateway Management Software. Restrict network access to the RADIUS configuration endpoint and implement robust input validation.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2025-71284 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.

CISA has added CVE-2025-71284 to the Known Exploited Vulnerabilities (KEV) catalog, confirming active exploitation in the wild. U.S. federal agencies are required to patch this within the mandated timeframe, and all organizations should treat remediation as urgent.
