Description

The Rockwell Automation Thinmanager Thinserver is impacted by an improper input validation vulnerability, an integer overflow condition exists in the affected products. When the ThinManager processes incoming messages, a read access violation occurs and terminates the process. A malicious user could exploit this vulnerability by sending a crafted synchronization protocol message and causing a denial of service condition in the software.

• CWE-20Improper Input ValidationThe product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.
• CWE-190Integer Overflow or WraparoundThe product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
