How the CVE Works
CVE-2025-28386 is a critical remote code execution vulnerability in OpenC3 COSMOS v6.0.0, specifically within its Plugin Management component. Attackers exploit this flaw by uploading a maliciously crafted `.txt` file, which bypasses input validation and allows arbitrary code execution on the target system. The vulnerability stems from insufficient file-type verification, enabling attackers to inject and execute harmful scripts under the application’s privileges. This can lead to full system compromise, data theft, or further network exploitation.
