What is CVE-2024-6868?

An arbitrary file write vulnerability exists in LocalAI version 2.17.1 due to improper handling of automatic archive extraction. When model configurations specify additional files in the form of archives such as .tar, these archives get automatically extracted post-download. This design flaw can be exploited through a 'tarslip' attack, allowing attackers to write files to arbitrary locations on the server. As a result, standard checks that limit file writing to the models directory can be bypassed, potentially leading to remote code execution (RCE) by overwriting critical backend assets utilized by the server.
