CVE-2025-30657
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L
Summary
An Improper Encoding or Escaping of Output vulnerability in the Sampling Route Record Daemon (SRRD) of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS).
When a device configured for flow-monitoring receives a specific BGP update message, it is correctly processed internally by the routing protocol daemon (rpd), but when it's sent to SRRD it's encoded incorrectly which leads to a crash and momentary interruption of jflow processing until it automatically restarts. This issue does not affect traffic forwarding itself. This issue affects Junos OS:
- All versions before 21.2R3-S9,
- 21.4 versions before 21.4R3-S10,
- 22.2 versions before 22.2R3-S6,
- 22.4 versions before 22.4R3,
- 23.2 versions before 23.2R1-S2, 23.2R2.
This issue does not affected Junos OS Evolved.
