Factorio · Factorio · CVE-2024-39840
**Name of the Vulnerable Software and Affected Versions**
Factorio versions prior to 1.1.101
**Description**
The issue allows a crafted server to execute arbitrary code on clients via a custom map. This is achieved by leveraging the ability of certain Lua base module functions to execute bytecode and generate fake objects.
**Recommendations**
For versions prior to 1.1.101, update to version 1.1.101 or later to resolve the issue. As a temporary workaround, consider restricting access to custom maps from untrusted sources to minimize the risk of exploitation.
