Details

Published Mar 21, 2024
CWE ID 863

Summary

CVE-2024-27933 is a vulnerability affecting Deno, a JavaScript, TypeScript, and WebAssembly runtime. In Deno version 1.39.0, a flaw in the `op_node_ipc_pipe()` function causes arbitrary file descriptors to be prematurely closed, enabling an attacker to re-open standard input (fd 0) as a different resource. This bypasses permission prompts, potentially leading to arbitrary code execution on the host machine. This issue is exploitable even in zero-permission scenarios, with a proven working exploit involving Cache API misuse. Version 1.39.1 addresses the vulnerability.
