Severity ?
7.3 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L
CWE
  • CWE-918 - Server-Side Request Forgery (SSRF)
Summary
libuv is a multi-platform support library with a focus on asynchronous I/O. The `uv_getaddrinfo` function in `src/unix/getaddrinfo.c` (and its windows counterpart `src/win/getaddrinfo.c`), truncates hostnames to 256 characters before calling `getaddrinfo`. This behavior can be exploited to create addresses like `0x00007f000001`, which are considered valid by `getaddrinfo` and could allow an attacker to craft payloads that resolve to unintended IP addresses, bypassing developer checks. The vulnerability arises due to how the `hostname_ascii` variable (with a length of 256 bytes) is handled in `uv_getaddrinfo` and subsequently in `uv__idna_toascii`. When the hostname exceeds 256 characters, it gets truncated without a terminating null byte. As a result attackers may be able to access internal APIs or for websites (similar to MySpace) that allows users to have `username.example.com` pages. Internal services that crawl or cache these user pages can be exposed to SSRF attacks if a malicious user chooses a long vulnerable username. This issue has been addressed in release version 1.48.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.

La funci\u00f3n `uv_getaddrinfo` en `src/unix/getaddrinfo.c` (y su contraparte de Windows `src/win/getaddrinfo.c`), trunca los nombres de host a 256 caracteres antes de llamar a `getaddrinfo`. Este comportamiento se puede aprovechar para crear direcciones como `0x00007f000001`, que `getaddrinfo` considera v\u00e1lidas y podr\u00edan permitir a un atacante crear payloads que se resuelvan en direcciones IP no deseadas, evitando las comprobaciones de los desarrolladores. La vulnerabilidad surge debido a c\u00f3mo se maneja la variable `hostname_ascii` (con una longitud de 256 bytes) en `uv_getaddrinfo` y posteriormente en `uv__idna_toascii`. Cuando el nombre de host supera los 256 caracteres, se trunca sin un byte nulo final. Como resultado, los atacantes pueden acceder a API internas o a sitios web (similares a MySpace) que permiten a los usuarios tener p\u00e1ginas `nombre de usuario.ejemplo.com`. Los servicios internos que rastrean o almacenan en cach\u00e9 estas p\u00e1ginas de usuario pueden quedar expuestos a ataques SSRF si un usuario malintencionado elige un nombre de usuario largo y vulnerable. Este problema se solucion\u00f3 en la versi\u00f3n 1.48.0. Se recomienda a los usuarios que actualicen.

The `uv_getaddrinfo` function in `src/unix/getaddrinfo.c` (and its windows counterpart `src/win/getaddrinfo.c`), truncates hostnames to 256 characters before calling `getaddrinfo`. This behavior can be exploited to create addresses like `0x00007f000001`, which are considered valid by `getaddrinfo` and could allow an attacker to craft payloads that resolve to unintended IP addresses, bypassing developer checks. The vulnerability arises due to how the `hostname_ascii` variable (with a length of 256 bytes) is handled in `uv_getaddrinfo` and subsequently in `uv__idna_toascii`. When the hostname exceeds 256 characters, it gets truncated without a terminating null byte. As a result attackers may be able to access internal APIs or for websites (similar to MySpace) that allows users to have `username.example.com` pages. Internal services that crawl or cache these user pages can be exposed to SSRF attacks if a malicious user chooses a long vulnerable username. This issue has been addressed in release version 1.48.0.
