The issue allows an out-of-bounds read in the core interpreter, leading to code execution. If a victim executes an attacker-controlled Squirrel script, it is possible for the attacker to break out of the Squirrel script sandbox, even if all dangerous functionality, such as File System functions, has been disabled. An attacker might abuse this bug to target Cloud services that allow customization via Squirrel scripts or distribute malware through video games that embed a Squirrel Engine.

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.

The issue allows remote attackers to execute arbitrary code due to the lack of proper validation of user-supplied data, resulting in a type confusion condition. Authentication is not required to exploit this issue. This is only applicable to installations using DNP3 Data Sets.

The issue allows remote attackers to disclose sensitive information due to the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated structure.
