An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2022-0028 in the wild since at least 22 Aug 2022.\n\nAffected product: Paloaltonetworks Pan-Os. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2022-0028/ (Markdown: https://insights.sbomify.com/CVE-2022-0028/index.md)","id":"CVE-2022-0028","markdown":"https://insights.sbomify.com/CVE-2022-0028/index.md","name":"CVE-2022-0028","record":{"aliases":["GHSA-r3j6-h9rm-9q33"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["denial_of_service","other"],"network_reachable":"yes","non_default_config":true,"product_category":"Palo Alto firewall","requires_auth":"none","summary":"Misconfigured URL filtering allows attackers to launch reflected DoS attacks, implicating the firewall as the source.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"palo_alto","cpe":[{"product":"pan-os","vendor":"paloaltonetworks"}],"cvss":{"score":8.6,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-406","name":"Insufficient Control of Network Message Volume (Network Amplification)"}],"description":"A PAN-OS URL filtering policy misconfiguration could allow a network-based attacker to conduct reflected and amplified TCP denial-of-service (RDoS) attacks. The DoS attack would appear to originate from a Palo Alto Networks PA-Series (hardware), VM-Series (virtual) and CN-Series (container) firewall against an attacker-specified target. To be misused by an external attacker, the firewall configuration must have a URL filtering profile with one or more blocked categories assigned to a source zone that has an external facing interface. This configuration is not typical for URL filtering and, if set, is likely unintended by the administrator. If exploited, this issue would not impact the confidentiality, integrity, or availability of our products. However, the resulting denial-of-service (DoS) attack may help obfuscate the identity of the attacker and implicate the firewall as the source of the attack. We have taken prompt action to address this issue in our PAN-OS software. All software updates for this issue are expected to be released no later than the week of August 15, 2022. This issue does not impact Panorama M-Series or Panorama virtual appliances. This issue has been resolved for all Cloud NGFW and Prisma Access customers and no additional action is required from them.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"exploited"},"has_fix":null,"headline":"Palo Alto Networks PAN-OS Reflected Amplification Denial-of-Service","id":"CVE-2022-0028","indexable":true,"kev":{"dateAdded":"2022-08-22","dueDate":"2022-09-12","knownRansomwareCampaignUse":"Unknown","product":"PAN-OS","requiredAction":"Apply updates per vendor instructions.","vendorProject":"Palo Alto Networks","vulnerabilityName":"Palo Alto Networks PAN-OS Reflected Amplification Denial-of-Service Vulnerability"},"kind":"cve","links":{"ecosystem":null,"product":"paloaltonetworks:pan-os","products":["paloaltonetworks:pan-os"],"type":"denial_of_service","year":"2022"},"n_packages":0,"n_references":1,"next":{"headline":"Cortex XDR Agent: Improper Link Resolution Vulnerability When Generating a Tech Support File","id":"CVE-2022-0029"},"packages":[],"prev":{"headline":"Cortex XSOAR: Incorrect Authorization Vulnerability When Generating Reports","id":"CVE-2022-0027"},"products":["Cloud NGFW","PAN-OS","Prisma Access"],"published":"2022-08-10","related":[{"cvss_score":10,"headline":"Palo Alto Networks PAN-OS Command Injection","id":"CVE-2024-3400","kev_date_added":"2024-04-12","published":"2024-04-12"},{"cvss_score":10,"headline":"Palo Alto Networks PAN-OS Authentication Bypass","id":"CVE-2020-2021","kev_date_added":"2022-03-25","published":"2020-06-29"},{"cvss_score":9.8,"headline":"Palo Alto Networks PAN-OS Remote Code Execution","id":"CVE-2017-15944","kev_date_added":"2022-08-18","published":"2017-12-11"},{"cvss_score":9.3,"headline":"Palo Alto Networks PAN-OS Out-of-bounds Write","id":"CVE-2026-0300","kev_date_added":"2026-05-06","published":"2026-05-06"},{"cvss_score":9.3,"headline":"Palo Alto Networks PAN-OS Management Interface Authentication Bypass","id":"CVE-2024-0012","kev_date_added":"2024-11-18","published":"2024-11-18"},{"cvss_score":9.2,"headline":"PHP Memory Corruption","id":"CVE-2026-109618","kev_date_added":"2026-10-26","published":"2026-10-21"},{"cvss_score":9.2,"headline":"PHP Stale Internal Request-State","id":"CVE-2026-109619","kev_date_added":"2026-10-26","published":"2026-10-21"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"open","licence":"CC0 1.0","name":"CISA KEV"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"active","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-10-21","vendors":["Palo Alto Networks"]},"summary":"Misconfigured URL filtering allows attackers to launch reflected DoS attacks, implicating the firewall as the source.","url":"https://insights.sbomify.com/CVE-2022-0028/"}
