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-2016-8900 in the wild and no public exploit code.\n\nAffected product: Exponentcms Exponent Cms. 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-2016-8900/ (Markdown: https://insights.sbomify.com/CVE-2016-8900/index.md)","id":"CVE-2016-8900","markdown":"https://insights.sbomify.com/CVE-2016-8900/index.md","name":"CVE-2016-8900","record":{"aliases":["GHSA-rw5c-588j-g4qf"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Exponent CMS","requires_auth":"none","summary":"An object injection vulnerability in Exponent CMS allows attackers to execute arbitrary code via the change_tags function.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"exponent_cms","vendor":"exponentcms"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"Exponent CMS version 2.3.9 suffers from a Object Injection vulnerability in framework/modules/core/controllers/expTagController.php related to change_tags.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Deserialization in n/a","id":"CVE-2016-8900","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"exponentcms:exponent_cms","products":["exponentcms:exponent_cms"],"type":"deserialization","year":"2016"},"n_packages":0,"n_references":2,"next":{"headline":"Deserialization in n/a","id":"CVE-2016-8901"},"packages":[],"prev":{"headline":"Deserialization in n/a","id":"CVE-2016-8899"},"products":["n/a"],"published":"2019-05-24","related":[{"cvss_score":9.8,"headline":"Exponent CMS before 2.6.0 has improper input validation in storeController.php.","id":"CVE-2016-9021","kev_date_added":null,"published":"2020-12-31"},{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2016-9022","kev_date_added":null,"published":"2020-12-31"},{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2016-9023","kev_date_added":null,"published":"2020-12-31"},{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-2016-9025","kev_date_added":null,"published":"2020-12-31"},{"cvss_score":9.8,"headline":"File upload in n/a","id":"CVE-2016-9026","kev_date_added":null,"published":"2020-12-31"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2016-8898","kev_date_added":null,"published":"2019-05-24"}],"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":"2024-08-06","vendors":["n/a"]},"summary":"An object injection vulnerability in Exponent CMS allows attackers to execute arbitrary code via the change_tags function.","url":"https://insights.sbomify.com/CVE-2016-8900/"}
