Detailsinfo

A vulnerability was found in hay86 ComfyUI-Ace-Nodes (the affected version is unknown) and classified as very critical. This issue affects the function eval. The manipulation with an unknown input leads to a code injection vulnerability. Using CWE to declare the problem leads to CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

ComfyUI-Ace-Nodes is vulnerable to Code Injection. The ACE_ExpressionEval node contains an eval() in its entrypoint function that accepts arbitrary user-controlled data. A user can create a workflow that results in executing arbitrary code on the server.

The advisory is shared at github.com. The identification of this vulnerability is CVE-2024-21577 since 12/22/2023. The exploitation is known to be easy. The attack may be initiated remotely.
