CVE-2022-28999Public exploitNetwork attack vector

Authenticated code execution via writable devcpp.exe binary

Published May 23, 2022 · Updated Aug 3, 2024

Incorrect default permissions in Bloodshed Dev-C++ 4.9.9.2 allow remote authenticated users to run code by replacing devcpp.exe. The installation leaves devcpp.exe and its containing directory writable, permitting substitution of a malicious executable that Dev-C++ later launches. A low-privileged account with write access to the installation is sufficient; the substituted code runs in the launching account's context.
