An improper access control vulnerability exists in the mintplex-labs/anything-llm application, specifically within the import endpoint. This vulnerability allows an anonymous attacker, without an account in the application, to import their own database file, leading to the deletion or spoofing of the existing anythingllm.db file. By exploiting this vulnerability, attackers can serve malicious data to users or collect information about them. The vulnerability stems from the applications failure to properly restrict access to the data-import functionality, allowing unauthorized database manipulation.
The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.
Access control involves the use of several protection mechanisms such as:
When any mechanism is not applied or otherwise fails, attackers can compromise the security of the product by gaining privileges, reading sensitive information, executing commands, evading detection, etc. There are two distinct behaviors that can introduce access control weaknesses:
