Detailsinfo

A vulnerability was found in SmartMesh (the affected version unknown) and classified as critical. This issue affects the function transferProxy. The manipulation of the argument _fee/_value as part of a Smart Contract leads to a integer overflow vulnerability. Using CWE to declare the problem leads to CWE-190. The 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 can introduce other weaknesses when the calculation is used for resource management or execution control. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

An integer overflow in the transferProxy function of a smart contract implementation for SmartMesh (aka SMT), an Ethereum ERC20 token, allows attackers to accomplish an unauthorized increase of digital assets via crafted _fee and _value parameters, as exploited in the wild in April 2018, aka the "proxyOverflow" issue.
