CVE-2025-30657

Media report

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.

CWE-116 Improper Encoding or Escaping of Output

The product prepares a structured message for communication with another component, but encoding or escaping of the data is either missing or done incorrectly. As a result, the intended structure of the message is not preserved.
