CVE-2024-30407
[Child CVE] JCNR and cRPD: Hard-coded SSH host keys in cRPD may allow Person-in-the-Middle (PitM) attacks
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.
