A vulnerability exists due to a small space of random values, which could allow an attacker to break encryption keys by capturing traffic between EcoStruxure Machine - Basic software and the Modicon controller. This can be exploited using a brute force attack, potentially allowing a remote attacker to bypass existing security restrictions.

A Missing Encryption of Sensitive Data issue exists that could allow an attacker to find the password hash when they have captured the traffic between EcoStruxure Machine - Basic software and the Modicon controller and broke the encryption keys. This could be exploited by a remote attacker to obtain the encryption key.

Name of the Vulnerable Software and Affected Versions: Mitsubishi Electric MC Works64 version 4.02C (10.95.208.31) and earlier Mitsubishi Electric MC Works32 version 3.00A (9.50.255.02) ICONICS GenBroker64, Platform Services, Workbench, FrameWorX Server version 10.96 and prior ICONICS GenBroker32 version 9.5 and prior Description: A specially crafted communication packet sent to the affected systems could cause a denial-of-service condition due to improper deserialization. The issue is related to deficiencies in the deserialization mechanism, which can be exploited by a remote attacker to cause a denial-of-service condition. Recommendations: For Mitsubishi Electric MC Works64 version 4.02C (10.95.208.31) and earlier, update to a version that fixes the deserialization issue. For Mitsubishi Electric MC Works32 version 3.00A (9.50.255.02), update to a version that fixes the deserialization issue. For ICONICS GenBroker64, Platform Services, Workbench, FrameWorX Server version 10.96 and prior, update to a version that fixes the deserialization issue. For ICONICS GenBroker32 version 9.5 and prior, update to a version that fixes the deserialization issue. As a temporary workaround, consider restricting access to the deserialization mechanism until a patch is available.

This issue is related to the restoration of an untrusted data structure in memory, which can be exploited by a remote attacker to execute arbitrary code or cause a denial-of-service. Recommendations: For Mitsubishi Electric MC Works64 version 4.02C (10.95.208.31) and earlier, update to a version later than 4.02C (10.95.208.31) to resolve the issue. For Mitsubishi Electric MC Works32 version 3.00A (9.50.255.02), update to a version later than 3.00A (9.50.255.02) to resolve the issue. For ICONICS GenBroker64, Platform Services, Workbench, FrameWorX Server version 10.96 and prior, update to a version later than 10.96 to resolve the issue. For ICONICS GenBroker32 version 9.5 and prior, update to a version later than 9.5 to resolve the issue. As a temporary workaround, consider restricting access to the deserialization functionality until a patch is available.
