![]() ![]() There is a working exploit that achieves arbitrary code execution by bypassing prompts from zero permissions, additionally abusing the fact that Cache API lacks filesystem permission checks. This is exploitable by an attacker controlling the code executed inside a Deno runtime to obtain arbitrary code execution on the host machine regardless of permissions. This allow standard input (fd 0) to be closed and re-opened for a different resource, which allows a silent permission prompt bypass. Use of raw file descriptors in `op_node_ipc_pipe()` leads to premature close of arbitrary file descriptors. On closing the resource, the raw file descriptor is closed together. ![]() Node child_process IPC relies on the JS side to pass the raw IPC file descriptor to `op_node_ipc_pipe()`, which returns a `IpcJsonStreamResource` ID associated with the file descriptor. In version 1.39.0, use of raw file descriptors in `op_node_ipc_pipe()` leads to premature close of arbitrary file descriptors, allowing standard input to be re-opened as a different resource resulting in permission prompt bypass. Jenkins HTML Publisher Plugin 1.16 through 1.32 (both inclusive) does not properly sanitize input, allowing attackers with Item/Configure permission to implement cross-site scripting (XSS) attacks and to determine whether a path on the Jenkins controller file system exists.ĭeno is a JavaScript, TypeScript, and WebAssembly runtime. Jenkins HTML Publisher Plugin 1.32 and earlier archives invalid symbolic links in report directories on agents and recreates them on the controller, allowing attackers with Item/Configure permission to determine whether a path on the Jenkins controller file system exists, without being able to access it.
