cRPD: Use of Hard-coded Cryptographic Key
CVE-2024-30407 is a high-severity use of hard-coded cryptographic key vulnerability in cRPD from Juniper Networks, with a CVSS 3.1 base score of 8.1 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists versions 23.4R1, 23.4r1 as the first without the flaw, so updating cRPD to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.68% chance of exploitation within 30 days, higher than 53% of scored CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update cRPD to 23.4R1 or 23.4r1, whichever matches your release line, or a later version.
- Update Juniper Cloud Native Router (JCNR) to 23.4 or a later version.
- Update cloud_native_router to 23.4 or a later version.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.
Affected products and versions
| Vendor | Product | Affected versions | Fixed in |
|---|---|---|---|
| Juniper Networks | cRPD | before 23.4R1; before 23.4r1 | 23.4R1, 23.4r1 |
| Juniper Networks | Juniper Cloud Native Router (JCNR) | before 23.4 | 23.4 |
| Juniper Networks | cloud_native_router | before 23.4 | 23.4 |

Official description
The Use of a Hard-coded Cryptographic Key vulnerability in Juniper Networks Juniper Cloud Native Router (JCNR) and containerized routing Protocol Deamon (cRPD) products allows an attacker to perform Person-in-the-Middle (PitM) attacks which results in complete compromise of the container. Due to hardcoded SSH host keys being present on the container, a PitM attacker can intercept SSH traffic without being detected. This issue affects Juniper Networks JCNR: * All versions before 23.4. This issue affects Juniper Networks cRPD: * All versions before 23.4R1.
