CyberRota Analysis
AI-GeneratedJuniper Networks Junos OS on various MX and SRX Series devices is vulnerable to a Denial-of-Service (DoS) attack due to an improper check for exceptional conditions in the Packet Forwarding Engine (PFE). An unauthenticated attacker can exploit this vulnerability by sending a specially crafted packet during a TCP connection, causing the PFE to crash and restart, disrupting all services until recovery. Organizations using affected versions of Junos OS should prioritize patching to mitigate potential service interruptions.
Original NVD Description
An Improper Check for Unusual or Exceptional Conditions vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS on MX with SPC3 and SRX Series allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS). When an affected device initiates a TCP connection to an attacker-controlled system that responds with a specific packet, this causes a PFE crash and restart, which affects all services until the system has automatically recovered. This issue can happen among others in the following scenarios: ALG, SSL proxy, UTM, RTLOG, AppQoE probing, AAMW, ICAP, URL filtering. This issue affects Junos OS on MX Series with SPC3, SRX5k Series with SPC3, SRX1600 Series, SRX2300 Series, SRX4000 Series, and vSRX Series: * all versions before 23.2R2-S4, * 23.4 versions before 23.4R2-S5, * 24.2 versions before 24.2R2.
