Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-43876 exists.\n\nAffected product: Octobercms October. 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-2023-43876/ (Markdown: https://insights.sbomify.com/CVE-2023-43876/index.md)","id":"CVE-2023-43876","markdown":"https://insights.sbomify.com/CVE-2023-43876/index.md","name":"CVE-2023-43876","record":{"aliases":[],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"October CMS","requires_auth":"low_privilege","summary":"An attacker can execute arbitrary web scripts via a crafted payload in the dbhost field during October CMS installation.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"october","vendor":"octobercms"}],"cvss":{"score":5.4,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A Cross-Site Scripting (XSS) vulnerability in installation of October v.3.4.16 allows an attacker to execute arbitrary web scripts via a crafted payload injected into the dbhost field.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2023-09-19","github_poc":1,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2023-09-19T23:05:11Z","kind":"github_poc","ref":"https://github.com/sromanhu/CVE-2023-43876-October-CMS-Reflected-XSS---Installation","stars":0,"title":"October CMS 3.4.16 is affected by a Cross-Site Scripting (XSS) vulnerability that allows attackers to execute arbitrary code via a crafted payload in the installation process."}],"tier":"weaponised"},"has_fix":null,"headline":"Cross-site scripting in n/a","id":"CVE-2023-43876","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"octobercms:october","products":["octobercms:october"],"type":"xss","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2023-43877"},"packages":[],"prev":{"headline":"Subrion CMS vulnerable to Cross-site Scripting","id":"CVE-2023-43875"},"products":["n/a"],"published":"2023-09-28","related":[{"cvss_score":8.2,"headline":"October CMS Improper Authentication","id":"CVE-2021-32648","kev_date_added":"2022-01-18","published":"2021-08-26"},{"cvss_score":9.8,"headline":"October CMS Session ID not invalidated after logout","id":"CVE-2021-3311","kev_date_added":null,"published":"2021-02-05"},{"cvss_score":9.8,"headline":"October CMS File Upload Vulnerability","id":"CVE-2017-1000194","kev_date_added":null,"published":"2017-11-17"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2017-1000196","kev_date_added":null,"published":"2017-11-17"},{"cvss_score":9.8,"headline":"Path traversal in n/a","id":"CVE-2017-1000197","kev_date_added":null,"published":"2017-11-17"},{"cvss_score":9.1,"headline":"October CMS safe mode bypass using Twig sandbox escape","id":"CVE-2023-44382","kev_date_added":null,"published":"2023-12-01"},{"cvss_score":8.8,"headline":"Authenticated file write leads to remote code execution in october/system","id":"CVE-2021-32649","kev_date_added":null,"published":"2022-01-14"}],"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":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-09-23","vendors":["n/a"]},"summary":"An attacker can execute arbitrary web scripts via a crafted payload in the dbhost field during October CMS installation.","url":"https://insights.sbomify.com/CVE-2023-43876/"}
