New CVE Detected

CVE-2026-78211 – Unauthenticated OS Command Injection (RCE) – 4MOSAn GCB Doctor < 20260621

Be the first to know when new zero-days emerge:

Summary

CVE-2026-78211 is a critical, unauthenticated OS command injection vulnerability in 4MOSAn GCB Doctor, a Taiwanese Government Configuration Baseline (GCB) compliance and vulnerability-scanning product developed by 4MOSAn Security Technology. The flaw resides in a leftover ADOdb test page that fails to sanitize a request parameter, allowing a remote, unauthenticated attacker to inject and execute arbitrary OS commands on the underlying server. The issue carries a CVSS v3.1 base score of 9.8 (Critical).

Technical details

  • Root cause: An ADOdb test/debug page shipped with 4MOSAn GCB Doctor was not removed from production builds. This page accepts a parameter that is passed unsanitized into a system command execution routine (CWE-78: OS Command Injection).
  • Trigger conditions: An attacker only needs network access to the exposed GCB Doctor web interface; no authentication, user interaction, or special privileges are required to reach the vulnerable endpoint.
  • Attack vector: Network (remote), low attack complexity — the attacker sends a crafted request with malicious shell metacharacters/commands in the vulnerable parameter of the ADOdb test page.
  • Impact: Successful exploitation results in arbitrary command execution with the privileges of the web service process, enabling full compromise of confidentiality, integrity, and availability of the host — including the underlying FreeBSD-based GCB management center.
  • Discovery/credit: Reported by security researcher Linwz (DEVCORE) via Taiwan’s TWCERT/CC coordinated disclosure process, with an advisory published August 24, 2026.

Affected software

  • 4MOSAn GCB Doctor — all versions prior to 20260621

Severity

  • CVSS v3.1 Base Score: 9.8 (Critical)
  • Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

Mitigation and recommended actions

  • Immediate: Upgrade 4MOSAn GCB Doctor to version 20260621 or later, and apply the accompanying FreeBSD-based GCB Management Center security upgrade as specified by the vendor.
  • If immediate patching is not possible:
    • Restrict network access to the GCB Doctor management interface to trusted internal hosts/VPN only; do not expose it directly to the internet.
    • Disable or remove any ADOdb test/debug pages or endpoints if identifiable on the deployed instance.
    • Monitor web server and application logs for unexpected requests to ADOdb-related paths and for anomalous child-process/command execution originating from the web service account.
    • Apply network segmentation and firewall rules to limit inbound access to the affected product until the patch can be applied.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
