CVE-2023-30588

Cuando se utiliza una clave pública no válida para crear x509 certificates utilizando la API crypto.X509Certificate(), se produce una terminación no esperada que la hace susceptible a ataques DoS cuando el atacante podría forzar interrupciones en el procesamiento de la aplicación, ya que el proceso finaliza al acceder a la información de clave pública de los certificados proporcionados desde el código de usuario. El contexto actual de los usuarios desaparecerá y eso provocará un escenario DoS. Esta vulnerabilidad afecta a todas las versiones activas de Node.js v16, v18 y v20.

A vulnerability has been identified in the Node.js, where an invalid public key is used to create an x509 certificate using the crypto.X509Certificate() API a non-expect termination occurs making it susceptible to DoS attacks when the attacker could force interruptions of application processing, as the process terminates when accessing public key info of provided certificates from user code. The current context of the users will be gone, and that will cause a DoS scenario.

It was discovered that Node.js incorrectly handled the use of invalid public keys while creating an x509 certificate. If a user or an automated system were tricked into opening a specially crafted input file, a remote attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 23.10. It was discovered that Node.js incorrectly handled the use of CRLF sequences to delimit HTTP requests. If a user or an automated system were tricked into opening a specially crafted input file, a remote attacker could possibly use this issue to obtain unauthorised access. This issue only affected Ubuntu 23.10.
