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-2023-45239 in the wild and no public exploit code.\n\nAffected product: Fedoraproject Fedora. 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-2023-45239/ (Markdown: https://insights.sbomify.com/CVE-2023-45239/index.md)","id":"CVE-2023-45239","markdown":"https://insights.sbomify.com/CVE-2023-45239/index.md","name":"CVE-2023-45239","record":{"aliases":["GHSA-p334-5r3g-4vx3"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"TACACS+ server","requires_auth":"none","summary":"Attackers can inject shell commands via controlled username or address fields in tac_plus when pre/post auth commands are enabled, leading to remote code execution.","user_interaction":"not_required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"facebook","cpe":[{"product":"tac_plus","vendor":"facebook"},{"product":"fedora","vendor":"fedoraproject"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-790","name":"Improper Filtering of Special Elements"}],"description":"A lack of input validation exists in tac_plus prior to commit 4fdf178 which, when pre or post auth commands are enabled, allows an attacker who can control the username, rem-addr, or NAC address sent to tac_plus to inject shell commands and gain remote code execution on the tac_plus server.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2024-04-29","github_poc":1,"max_poc_stars":1,"metasploit":0,"nuclei":0,"refs":[{"date":"2024-04-29T18:48:57Z","kind":"github_poc","ref":"https://github.com/takeshixx/tac_plus-pre-auth-rce","stars":1,"title":"tac_plus Pre-Auth Remote Command Execution Vulnerability (CVE-2023-45239 \u0026 CVE-2023-48643)"}],"tier":"poc_unverified"},"has_fix":false,"headline":"Command injection in tac plus","id":"CVE-2023-45239","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"fedoraproject:fedora","products":["fedoraproject:fedora"],"type":"command_injection","year":"2023"},"n_packages":0,"n_references":3,"next":{"headline":"Missing authorization in Acronis Agent","id":"CVE-2023-45240"},"packages":[],"prev":{"headline":"Use of a Weak PseudoRandom Number Generator in EDK II Network Package","id":"CVE-2023-45237"},"products":["tac_plus"],"published":"2023-10-06","related":[],"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":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2025-02-13","vendors":["Meta"]},"summary":"Attackers can inject shell commands via controlled username or address fields in tac_plus when pre/post auth commands are enabled, leading to remote code execution.","url":"https://insights.sbomify.com/CVE-2023-45239/"}
