Description

MaxKB is an open-source AI assistant for enterprise. Prior to version 1.10.8-lts, Sandbox only restricts the execution permissions of binary files in common directories, such as `/bin,/usr/bin`, etc. Therefore, attackers can exploit some files with execution permissions in non blacklisted directories to carry out attacks. Version 1.10.8-lts fixes the issue.

Affected products

1Panel-dev MaxKB: before 1.10.8 — fixed in 1.10.8

How to fix

Upgrade to a fixed version: 1Panel-dev MaxKB 1.10.8. Check the vendor advisory for mitigations.
