This happens because the payload-protocol match criteria is not supported in the kernel filter causing it to accept all packets without taking any other action. As a fix the payload-protocol match will be treated the same as a \"next-header\" match to avoid this filter bypass.\n\nThis issue doesn't affect IPv4 firewall filters.\n\nThis issue affects Juniper Networks Junos OS on MX Series and EX9200 Series:\n\n\n\n * All versions earlier than 20.4R3-S7;\n * 21.1 versions earlier than 21.1R3-S5;\n * 21.2 versions earlier than 21.2R3-S5;\n * 21.3 versions earlier than 21.3R3-S4;\n * 21.4 versions earlier than 21.4R3-S4;\n * 22.1 versions earlier than 22.1R3-S2;\n * 22.2 versions earlier than 22.2R3-S2;\n * 22.3 versions earlier than 22.3R2-S2, 22.3R3;\n * 22.4 versions earlier than 22.4R1-S2, 22.4R2-S2, 22.4R3.\n\n\n\n\n\n\n" } ] }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "CWE-447 Unimplemented or Unsupported Feature in UI", "cweId": "CWE-447" } ] } ] }, "affects": { "vendor": { "vendor_data": [ { "vendor_name": "Juniper Networks", "product": { "product_data": [ { "product_name": "Junos OS", "version": { "version_data": [ { "version_affected": "<", "version_name": "0", "version_value": "20.4R3-S7" }, { "version_affected": "<", "version_name": "21.1", "version_value": "21.1R3-S5" }, { "version_affected": "<", "version_name": "21.2", "version_value": "21.2R3-S5" }, { "version_affected": "<", "version_name": "21.3", "version_value": "21.3R3-S4" }, { "version_affected": "<", "version_name": "21.4", "version_value": "21.4R3-S4" }, { "version_affected": "<", "version_name": "22.1", "version_value": "22.1R3-S2" }, { "version_affected": "<", "version_name": "22.2", "version_value": "22.2R3-S2" }, { "version_affected": "<", "version_name": "22.3", "version_value": "22.3R2-S2, 22.3R3" }, { "version_affected": "<", "version_name": "22.4", "version_value": "22.4R1-S2, 22.4R2-S2, 22.4R3" } ] } } ] } } ] } }, "references": { "reference_data": [ { "url": "https://supportportal.juniper.net/JSA75748", "refsource": "MISC", "name": "https://supportportal.juniper.net/JSA75748" }, { "url": "https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N", "refsource": "MISC", "name": "https://www.first.org/cvss/calculator/4.0#CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N" } ] }, "generator": { "engine": "Vulnogram 0.1.0-av217" }, "source": { "advisory": "JSA75748", "defect": [ "1689224" ], "discovery": "USER" }, "configuration": [ { "lang": "en", "supportingMedia": [ { "base64": false, "type": "text/html", "value": "
