CVE-2020-19301Public exploitNetwork attack vector

Arbitrary code execution via crafted role condition

Published Aug 3, 2021 · Updated Aug 4, 2024

Code injection in vaeThink 1.0.1 allows remote attackers to execute arbitrary code through a crafted condition field value. The vae_admin_rule.condition value is passed as an argument to a code-execution function in the administrator privilege-check module without restricting executable syntax. Execution occurs when the system checks privileges for a user assigned to the crafted role; the public proof of concept first creates that role and user.
