CyberRota Analysis
AI-GeneratedThe SIP plugin in Juniper Networks Junos OS on MX Series with SPC3 and SRX Series is vulnerable to an improper validation of input, allowing unauthenticated attackers to exploit malformed SIP invite packets. This can lead to a Denial-of-Service (DoS) condition, causing the flow processing daemon to crash and resulting in a complete service outage until recovery occurs. Organizations using affected versions of Junos OS should prioritize patching to mitigate this high-severity vulnerability.
Original NVD Description
An Improper Validation of Syntactic Correctness of Input vulnerability in the SIP plugin of Juniper Networks Junos OS on MX Series with SPC3 and SRX Series allows an unauthenticated, network-based attacker to cause a Denial-of-Service (DoS).If the SIP ALG is enabled on an affected device, the processing of a malformed SIP invite packet will cause a flow processing daemon (flowd) crash and restart. This leads to a complete service outage until the system has automatically recovered. This issue affects Junos OS on MX Series with SPC3 and SRX Series: * all versions before 23.2R2-S7, * 23.4 versions before 23.4R2-S8, * 24.2 versions before 24.2R2-S5, * 24.4 versions before 24.4R2-S4, * 25.2 versions before 25.2R2, * 25.4 versions before 25.4R1-S2.
