CVE-2025-31490

Estado: AnalizadaAlta (7.5)—

AutoGPT is a platform that allows users to create, deploy, and manage continuous artificial intelligence agents that automate complex workflows. Prior to 0.6.1, AutoGPT allows SSRF due to DNS Rebinding in requests wrapper. AutoGPT is built with a wrapper around Python's requests library, hardening the application against SSRF. The code for this wrapper can be found in autogpt_platform/backend/backend/util/request.py. The requested hostname of a URL which is being requested is validated, ensuring that it does not resolve to any local ipv4 or ipv6 addresses.

However, this check is not sufficient, as a DNS server may initially respond with a non-blocked address, with a TTL of 0. This means that the initial resolution would appear as a non-blocked address. In this case, validate_url() will return the url as successful. After validate_url() has successfully returned the url, the url is then passed to the real request() function. When the real request() function is called with the validated url, request() will once again resolve the address of the hostname, because the record will not have been cached (due to TTL 0). This resolution may be in the "invalid range". This type of attack is called a "DNS Rebinding Attack". This vulnerability is fixed in 0.6.1.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

AV:N/PR:N/UI:N indica explotación remota sin privilegios (T1190). DNS Rebinding permite SSRF para acceder a recursos locales; T1090 es proxy/redirección, T1005 es acceso a datos en el sistema local.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.

      "value": "AutoGPT es una plataforma que permite a los usuarios crear, implementar y gestionar agentes continuos de inteligencia artificial que automatizan flujos de trabajo complejos. Antes de la versión 0.6.1, AutoGPT permitía SSRF gracias a la revinculación de DNS en el contenedor de solicitudes. AutoGPT se basa en un contenedor alrededor de la librería de solicitudes de Python, lo que refuerza la aplicación contra SSRF. El código de este contenedor se encuentra en autogpt_platform/backend/backend/util/request.py. Se valida el nombre de host de la URL solicitada, lo que garantiza que no se resuelva a ninguna dirección IPv4 o IPv6 local. Sin embargo, esta comprobación no es suficiente, ya que un servidor DNS podría responder inicialmente con una dirección no bloqueada, con un TTL de 0. Esto significa que la resolución inicial aparecería como una dirección no bloqueada. En este caso, validate_url() devolverá la URL como correcta. Una vez que validate_url() haya devuelto la URL correctamente, esta se pasa a la función request() real. Al llamar a la función request() con la URL validada, request() resolverá de nuevo la dirección del nombre de host, ya que el registro no se habrá almacenado en caché (debido al TTL 0). Esta resolución podría estar en el rango inválido. Este tipo de ataque se denomina \"Ataque de Revinculación DNS\". Esta vulnerabilidad se corrigió en la versión 0.6.1."
