An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: Yes. Attackers have exploited CVE-2020-14871 in the wild since at least 3 Nov 2021.\n\nAffected product: Oracle Solaris. 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-2020-14871/ (Markdown: https://insights.sbomify.com/CVE-2020-14871/index.md)","id":"CVE-2020-14871","markdown":"https://insights.sbomify.com/CVE-2020-14871/index.md","name":"CVE-2020-14871","record":{"aliases":["GHSA-7pcp-8fjh-246q"],"analysis":{"component_type":"operating_system","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Oracle Solaris OS","requires_auth":"none","summary":"Unauthenticated attackers can achieve full system takeover via a memory corruption flaw in the Pluggable Authentication Module.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"oracle","cpe":[{"product":"solaris","vendor":"oracle"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Vulnerability in the Oracle Solaris product of Oracle Systems (component: Pluggable authentication module).
