Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-18121 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2020-18121/ (Markdown: https://insights.sbomify.com/CVE-2020-18121/index.md)","id":"CVE-2020-18121","markdown":"https://insights.sbomify.com/CVE-2020-18121/index.md","name":"CVE-2020-18121","record":{"aliases":["GHSA-vjc4-8cmg-4xxh"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Indexhibit CMS","requires_auth":"low_privilege","summary":"Authenticated attackers can modify PHP files due to insecure permissions, leading to remote code execution.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"indexhibit","vendor":"indexhibit"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-732","name":"Incorrect Permission Assignment for Critical Resource"}],"description":"A configuration issue in Indexhibit 2.1.5 allows authenticated attackers to modify .php files, leading to getshell.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"File upload in n/a","id":"CVE-2020-18121","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site request forgery in n/a","id":"CVE-2020-18123"},"packages":[],"prev":{"headline":"SQL injection in n/a","id":"CVE-2020-18116"},"products":["n/a"],"published":"2021-08-30","related":[{"cvss_score":9.8,"headline":"Missing authorization in n/a","id":"CVE-2019-16314","kev_date_added":null,"published":"2019-09-14"},{"cvss_score":8.8,"headline":"Code injection in n/a","id":"CVE-2019-8954","kev_date_added":null,"published":"2019-02-20"},{"cvss_score":6.5,"headline":"Cross-site request forgery in n/a","id":"CVE-2020-18123","kev_date_added":null,"published":"2021-08-30"},{"cvss_score":6.5,"headline":"Path traversal in n/a","id":"CVE-2020-18127","kev_date_added":null,"published":"2021-08-30"},{"cvss_score":6.1,"headline":"Cross-site scripting in n/a","id":"CVE-2020-18125","kev_date_added":null,"published":"2021-08-30"},{"cvss_score":5.7,"headline":"Cross-site request forgery in n/a","id":"CVE-2020-18124","kev_date_added":null,"published":"2021-08-30"}],"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)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-04","vendors":["n/a"]},"summary":"Authenticated attackers can modify PHP files due to insecure permissions, leading to remote code execution.","url":"https://insights.sbomify.com/CVE-2020-18121/"}
