CVE-2022-29376Network attack vector

Code execution via writable installation binary replacement

Published May 23, 2022 · Updated Aug 15, 2025

Incorrect permissions in XAMPP for Windows 8.1.4 and earlier allow attackers to execute arbitrary code by overwriting installed binaries. The installation directory permits write access that lets attacker-controlled files replace binaries located there. Exploitation requires write access to that directory and later execution of a replaced binary; the public references identify no specific binary or overwrite path.
