CVE-2023-22411
Last modified
CVE-2023-22411 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. An Out-of-Bounds Write vulnerability in Flow Processing Daemon (flowd) of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause Denial of Service (DoS). On SRX Series devices using Unified Policies with IPv6, when a specific IPv6 packet goes through a dynamic-application filter which will generate an ICMP deny message, the flowd core is observed and the PFE is restarted. EPSS estimates a 0.62% chance of exploitation in the next 30 days.
Description
An Out-of-Bounds Write vulnerability in Flow Processing Daemon (flowd) of Juniper Networks Junos OS allows an unauthenticated, network-based attacker to cause Denial of Service (DoS). On SRX Series devices using Unified Policies with IPv6, when a specific IPv6 packet goes through a dynamic-application filter which will generate an ICMP deny message, the flowd core is observed and the PFE is restarted.
