CVE-2025-30649

Medienbericht
An Improper Input Validation vulnerability in the syslog stream TCP transport of Juniper Networks Junos OS on MX240, MX480 and MX960 devices with MX-SPC3 Security Services Card allows an unauthenticated, network-based attacker, to send specific spoofed packets to cause a CPU Denial of Service (DoS) to the MX-SPC3 SPUs.

Continued receipt and processing of these specific packets will sustain the DoS condition.

This issue affects Junos OS:  *  All versions before 22.2R3-S6,
  *  from 22.4 before 22.4R3-S4,
  *  from 23.2 before 23.2R2-S3,
  *  from 23.4 before 23.4R2-S4,
  *  from 24.2 before 24.2R1-S2, 24.2R2


An indicator of compromise will indicate the SPC3 SPUs utilization has spiked.


For example:
