An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-1992 in the wild and no public exploit code.\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-2020-1992/ (Markdown: https://insights.sbomify.com/CVE-2020-1992/index.md)","id":"CVE-2020-1992","markdown":"https://insights.sbomify.com/CVE-2020-1992/index.md","name":"CVE-2020-1992","record":{"aliases":["GHSA-rpm3-9x65-q856"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Palo Alto firewall","requires_auth":"none","summary":"Remote attackers can crash the Varrcvr daemon or execute code with root privileges on PA-7000 firewalls with Log Forwarding Cards.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"palo_alto","cpe":[{"product":"pan-os","vendor":"paloaltonetworks"}],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-134","name":"Use of Externally-Controlled Format String"}],"description":"A format string vulnerability in the Varrcvr daemon of PAN-OS on PA-7000 Series devices with a Log Forwarding Card (LFC) allows remote attackers to crash the daemon creating a denial of service condition or potentially execute code with root privileges.
