A vulnerability has been identified in COMOS V10.3 (All versions < V10.3.3.5.8), COMOS V10.4.0 (All versions), COMOS V10.4.1 (All versions), COMOS V10.4.2 (All versions), COMOS V10.4.3 (All versions < V10.4.3.0.47), COMOS V10.4.4 (All versions < V10.4.4.2), COMOS V10.4.4.1 (All versions < V10.4.4.1.21). The PDMS/E3D Engineering Interface improperly handles XML External Entity (XXE) entries when communicating with an external application. This could allow an attacker to extract any file with a known location on the user's system or accessible network folders by injecting malicious data into the communication channel between the two systems.
