CyberRota Analysis
AI-GeneratedThe TCP proxy 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 TCP packets, resulting in a complete Denial of Service (DoS) that disrupts service until the system automatically recovers. Organizations using affected versions (23.4 prior to 23.4R2-S7, 24.2 prior to 24.2R2-S4, 24.4 prior to 24.4R2-S3, and 25.2 prior to 25.2R2) should prioritize remediation to mitigate potential service outages.
Original NVD Description
An Improper Validation of Specified Quantity in Input vulnerability in the TCP proxy plugin of Juniper Networks Junos OS on MX Series with SPC3, and SRX Series allows an unauthenticated, network-based attacker to cause a complete Denial of Service (DoS). When TCP proxy is engaged in a flow session, to support ALGs, Advanced Anti-Malware, ICAP or UTM, a TCP packet with specifically malformed TCP header will cause flow processing daemon (flowd) to crash and restart. This causes a complete service outage until the system has automatically recovered. This issue affects Junos OS on MX with SPC3, and SRX Series: * 23.4 versions before 23.4R2-S7, * 24.2 versions before 24.2R2-S4, * 24.4 versions before 24.4R2-S3, * 25.2 versions before 25.2R2. This issue does not affect releases before 23.4R1.
