Over time, this leads to resource exhaustion, ultimately causing the device to crash and restart.\n\nThe following command can be used to monitor the resource usage:\nuser@host> show system processes extensive | match mgd | count\n\nThis issue affects Junos OS on SRX Series and EX Series:\nAll versions before 21.4R3-S7,\nfrom 22.2 before 22.2R3-S4,\nfrom 22.3 before 22.3R3-S3,\nfrom 22.4 before 22.4R3-S2,\nfrom 23.2 before 23.2R2-S1,\nfrom 23.4 before 23.4R1-S2, 23.4R2.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/R:A","score":8.7},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":7.5},"cwes":["CWE-400"],"references":["https://supportportal.juniper.net/"],"products":["juniper:junos"],"source":"nvd","synced_at":"2026-10-19T21:55:31.737901711+00:00"},"epss":{"cve":"CVE-2024-47497","score":0.00599,"percentile":0.4869,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
