CVE-2024-30397

  1. OpenCVE
  2. Vulnerabilities (CVE)
  3. CVE-2024-30397
An Improper Check for Unusual or Exceptional Conditions vulnerability in the the Public Key Infrastructure daemon (pkid) of Juniper Networks Junos OS allows an unauthenticated networked attacker to cause Denial of Service (DoS). The pkid is responsible for the certificate verification. Upon a failed verification, the pkid uses all CPU resources and becomes unresponsive to future verification attempts. This means that all subsequent VPN negotiations depending on certificate verification will fail. This CPU utilization of pkid can be checked using this command:   root@srx> show system processes extensive | match pkid   xxxxx ?root ?103? 0 ?846M ?136M ?CPU1 ?1 569:00 100.00% pkid This issue affects: Juniper Networks Junos OS All versions prior to 20.4R3-S10; 21.2 versions prior to 21.2R3-S7; 21.4 versions prior to 21.4R3-S5; 22.1 versions prior to 22.1R3-S4; 22.2 versions prior to 22.2R3-S3; 22.3 versions prior to 22.3R3-S1; 22.4 versions prior to 22.4R3; 23.2 versions prior to 23.2R1-S2, 23.2R2.

Summary
  • (es) Una vulnerabilidad de verificación inadecuada de condiciones inusuales o excepcionales en el daemon de infraestructura de clave pública (pkid) de Juniper Networks Junos OS permite que un atacante en red no autenticado provoque una denegación de servicio (DoS). El pkid es responsable de la verificación del certificado. Tras una verificación fallida, el pkid utiliza todos los recursos de la CPU y deja de responder a futuros intentos de verificación. Esto significa que todas las negociaciones VPN posteriores que dependan de la verificación del certificado fallarán. Esta utilización de CPU de pkid se puede verificar usando este comando: root@srx> mostrar procesos del sistema extensos | coincide con pkid xxxxx root 103 0 846M 136M CPU1 1 569:00 100.00% pkid Este problema afecta a: Juniper Networks Junos OS Todas las versiones anteriores a 20.4R3-S10; Versiones 21.2 anteriores a 21.2R3-S7; Versiones 21.4 anteriores a 21.4R3-S5; Versiones 22.1 anteriores a 22.1R3-S4; Versiones 22.2 anteriores a 22.2R3-S3; Versiones 22.3 anteriores a 22.3R3-S1; Versiones 22.4 anteriores a 22.4R3; Versiones 23.2 anteriores a 23.2R1-S2, 23.2R2.
