FKIE_CVE-2018-10769

Vulnerability from fkie_nvd - Published: 2018-08-10 15:29 - Updated: 2026-06-17 01:34
Severity
7.5 (High) - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N
Summary
The transferProxy and approveProxy functions of a smart contract implementation for SmartMesh (SMT), an Ethereum ERC20 token, allow attackers to accomplish an unauthorized transfer of digital assets because replay attacks can occur with the same-named functions (with the same signatures) in other tokens: First (FST), GG Token (GG), M2C Mesh Network (MTC), M2C Mesh Network (mesh), and UG Token (UGT).
