CVE-2024-4287 is a high-severity improper input validation vulnerability in mintplex-labs/anything-llm from Mintplex-labs, with a CVSS 3.1 base score of 7.2 out of 10. It can be exploited remotely over the network by an attacker with administrator privileges, without any action from a user. The record lists version 0.0.0 as the first without the flaw, so updating mintplex-labs/anything-llm to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.61% chance of exploitation within 30 days, which is low compared with other CVEs.

Official description

In mintplex-labs/anything-llm, a vulnerability exists due to improper input validation in the workspace update process. Specifically, the application fails to validate or format JSON data sent in an HTTP POST request to `/api/workspace/:workspace-slug/update`, allowing it to be executed as part of a database query without restrictions. This flaw enables users with a manager role to craft a request that includes nested write operations, effectively allowing them to create new Administrator accounts.

The underlying weakness: Improper Input Validation

The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly.

How developers prevent this class of flaw

  • Consider using language-theoretic security (LangSec) techniques that characterize inputs using a formal language and build recognizers for that language. This effectively requires parsing to be a distinct layer that effectively enforces a boundary between raw input and internal data representations, instead of allowing parser code to be scattered throughout the program, where it could be subject to errors or inconsistencies that create weaknesses.
  • Use an input validation framework such as Struts or the OWASP ESAPI Validation API. Note that using a framework does not automatically address all input validation problems; be mindful of weaknesses that could arise from misusing the framework itself (CWE-1173).
  • Understand all the potential areas where untrusted inputs can enter the product, including but not limited to: parameters or arguments, cookies, anything read from the network, environment variables, reverse DNS lookups, query results, request headers, URL components, e-mail, files, filenames, databases, and any external systems that provide data to the application. Remember that such inputs may be obtained indirectly through API calls.
