CVE-2024-47497 Information

Description

An Uncontrolled Resource Consumption vulnerability in the http daemon (httpd) of Juniper Networks Junos OS on SRX Series QFX Series MX Series and EX Series allows an unauthenticated network-based attacker to cause Denial-of-Service (DoS).

An attacker can send specific HTTPS connection requests to the device triggering the creation of processes that are not properly terminated. Over time this leads to resource exhaustion ultimately causing the device to crash and restart.

The following command can be used to monitor the resource usage: user@host> show system processes extensive | match mgd | count

This issue affects Junos OS on SRX Series and EX Series: All versions before 21.4R3-S7 from 22.2 before 22.2R3-S4 from 22.3 before 22.3R3-S3 from 22.4 before 22.4R3-S2 from 23.2 before 23.2R2-S1 from 23.4 before 23.4R1-S2 23.4R2.
