CVE-2022-22153
Last modified
CVE-2022-22153 is a high-severity vulnerability rated 7.5/10 on the CVSS scale. An Insufficient Algorithmic Complexity combined with an Allocation of Resources Without Limits or Throttling vulnerability in the flow processing daemon (flowd) of Juniper Networks Junos OS on SRX Series and MX Series with SPC3 allows an unauthenticated network attacker to cause latency in transit packet processing and even packet loss. If transit traffic includes a significant percentage (> 5%) of fragmented packets which need to be reassembled, high latency or packet drops might be observed. EPSS estimates a 0.93% chance of exploitation in the next 30 days.
