The vulnerability originates from improper neutralization of special elements in file paths, allowing an unauthenticated remote attacker to perform a relative path traversal attack. By supplying specially crafted input to vulnerable application endpoints, an attacker can bypass directory restrictions to access and download arbitrary files from the underlying host filesystem. This flaw poses a significant risk to confidentiality, as it could permit the unauthorized retrieval of configuration files, credentials, or other sensitive system data. Defenders should prioritize patching affected instances to the latest available version provided by 4MOSAn Security Technology.

Attack Chain

1. The attacker performs reconnaissance to identify internet-facing 4MOSAn Management Center instances.
2. The attacker sends an unauthenticated HTTP request to a vulnerable application endpoint.
3. The request includes a manipulated parameter containing directory traversal sequences (e.g., ../../../).
4. The application processes the input without sufficient validation of the requested file path.
5. The server-side code resolves the traversal path to access files outside of the intended directory.
6. The application reads the contents of the targeted system file and includes it in the HTTP response body.
7. The attacker receives the sensitive file content, completing the unauthorized data exfiltration.

Impact

Successful exploitation allows unauthenticated attackers to read any file on the server accessible to the web application process. This can lead to the exposure of credentials, database configurations, and environment secrets, facilitating further compromise of the internal network and associated systems.

Recommendation

• Patch 4MOSAn Management Center to version 20260621 or later immediately to remediate CVE-2026-78212.
• Monitor webserver logs for HTTP requests containing directory traversal sequences (e.g., '..%2f', '..%5c', or repeated '../') directed at application parameters.
• Restrict external access to 4MOSAn Management Center interfaces using firewall rules or VPNs to minimize the exposure window for unauthenticated exploitation attempts.

This vulnerability allows unauthenticated remote attackers to send crafted HTTP requests to the vulnerable test page, enabling the injection and execution of arbitrary OS-level commands on the affected server. Given the nature of the software, successful exploitation grants the attacker full control over the host environment. Defenders should prioritize patching or removing the insecure test files immediately.

Attack Chain

1. Attacker performs reconnaissance to identify instances of 4MOSAn GCB Doctor.
2. Attacker probes the web server for the presence of the known vulnerable ADOdb test page.
3. Attacker sends a crafted HTTP request to the discovered ADOdb test page path.
4. The input parameter within the request is passed unsanitized to a system shell.
5. The server process executes the attacker-supplied command with the privileges of the web service account.
6. Attacker confirms successful command injection through server responses or out-of-band callbacks.
7. Attacker performs post-exploitation activities, such as establishing persistence or exfiltrating data.

Impact

Successful exploitation of this vulnerability leads to unauthenticated remote code execution on the underlying server. This can result in complete system compromise, unauthorized access to sensitive configuration files, and potential pivot points into the internal network. No specific victim counts have been reported, but organizations utilizing 4MOSAn GCB Doctor versions prior to 20260621 are considered at high risk.

Recommendation

• Apply the security update to 4MOSAn GCB Doctor version 20260621 or later.
• If patching is not immediately feasible, identify and delete the ADOdb test page files from the web root to prevent exploitation.
• Enable web server access logging and audit requests targeting suspicious file paths associated with ADOdb test tools.
• Deploy the provided Sigma rule to detect attempts to reach the known vulnerable endpoint.
