Detailsinfo

A vulnerability, which was classified as critical, has been found in Deno up to 1.31.1. This issue affects the function op_spawn_child/op_kill of the component Program Name Handler. The manipulation with an unknown input leads to a control sequence vulnerability. Using CWE to declare the problem leads to CWE-150. The product receives input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could be interpreted as escape, meta, or control character sequences when they are sent to a downstream component. Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Deno is a simple, modern and secure runtime for JavaScript and TypeScript that uses V8 and is built in Rust. Arbitrary program names without any ANSI filtering allows any malicious program to clear the first 2 lines of a `op_spawn_child` or `op_kill` prompt and replace it with any desired text. This works with any command on the respective platform, giving the program the full ability to choose what program they wanted to run. This problem can not be exploited on systems that do not attach an interactive prompt (for example headless servers). This issue has been patched in version 1.31.2.
