Summary

GREENmod uses named pipes for communication between plugins, the web portal, and the system service, but the access control lists are misconfigured. An attacker can communicate with the stream and upload arbitrary XML or JSON files processed with the service user's privileges, enabling Server-Side Request Forgery to Windows systems via SMB or WebDAV.

Risk Assessment

An attacker could make requests to internal Windows systems with service privileges, potentially leading to further exploitation or data leakage.

Recommendation

Upgrade GREENmod to version 2.8.33, which fixes the issue.

Original NVD description (English source)

GREENmod uses named pipes for communication between plugins, the web portal, and the system service, but the access control lists for these pipes are configured incorrectly. This allows an attacker to communicate with the stream and upload any XML or JSON file, which will be processed by the named pipe with the privileges of the user under whose context the service is running. This allows for Server-Side Request Forgery to any Windows system on which the agent is installed and which provides communication via SMB or WebDav. This issue was fixed in version 2.8.33.
