CVE-2024-47506
Junos OS: SRX Series: A large amount of traffic being processed by ATP Cloud can lead to a PFE crash
A Deadlock vulnerability in the packet forwarding engine (PFE) of Juniper Networks Junos OS on SRX Series allows an unauthenticated, network-based attacker to cause a Denial of Service (DoS).
When a large amount of traffic is processed by ATP Cloud inspection, a deadlock can occur which will result in a PFE crash and restart. Whether the crash occurs, depends on system internal timing that is outside the attackers control.
This issue affects Junos OS on SRX Series:
- All versions before 21.3R3-S1,
- 21.4 versions before 21.4R3,
- 22.1 versions before 22.1R2,
- 22.2 versions before 22.2R1-S2, 22.2R2.
