Vulnerability from fkie_nvd - Published: 2024-06-19 20:15 - Updated: 2024-11-21 09:25
Severity ?
2.9 (Low) - CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N
Summary
Wasmer is a web assembly (wasm) Runtime supporting WASIX, WASI and Emscripten. If the preopened directory has a symlink pointing outside, WASI programs can traverse the symlink and access host filesystem if the caller sets both `oflags::creat` and `rights::fd_write`. Programs can also crash the runtime by creating a symlink pointing outside with `path_symlink` and `path_open`ing the link. This issue has been addressed in commit `b9483d022` which has been included in release version 4.3.2. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Si el directorio preabierto tiene un enlace simb\u00f3lico que apunta hacia afuera, los programas WASI pueden atravesar el enlace simb\u00f3lico y acceder al sistema de archivos del host si la persona que llama configura tanto `oflags::creat` como `rights::fd_write`. Los programas tambi\u00e9n pueden bloquear el tiempo de ejecuci\u00f3n al crear un enlace simb\u00f3lico que apunte hacia afuera con `path_symlink` y `path_open` en el enlace. Este problema se solucion\u00f3 en el commit `b9483d022` que se incluy\u00f3 en la versi\u00f3n 4.3.2. Se recomienda a los usuarios que actualicen.
