CVE-2023-0104Network attack vector

System compromise via ZipSlip project decompilation

Published Feb 22, 2023 · Updated Jan 16, 2025

Path traversal in EasyBuilder Pro 6.07.01, 6.07.02.479, and 6.08.01.349 and earlier allows remote attackers to compromise a PC. During decompilation, the project-file extractor accepts backslash-dot-dot path sequences in archive entries and writes outside its intended directory. Exploitation requires a user to decompile an attacker-supplied project and results in sensitive-file access or control of the user's computer.
