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-2016-3154 in the wild and no public exploit code.\n\nAffected product: Spip Spip. 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-2016-3154/ (Markdown: https://insights.sbomify.com/CVE-2016-3154/index.md)","id":"CVE-2016-3154","markdown":"https://insights.sbomify.com/CVE-2016-3154/index.md","name":"CVE-2016-3154","record":{"aliases":["DEBIAN-CVE-2016-3154","GHSA-5fwq-26jx-xp73","UBUNTU-CVE-2016-3154"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"SPIP CMS","requires_auth":"none","summary":"Remote attackers can execute arbitrary PHP code in SPIP CMS via crafted serialized objects in the encoder_contexte_ajax function.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"spip","vendor":"spip"}],"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-94","name":"Improper Control of Generation of Code"}],"description":"The encoder_contexte_ajax function in ecrire/inc/filtres.php in SPIP 2.x before 2.1.19, 3.0.x before 3.0.22, and 3.1.x before 3.1.1 allows remote attackers to conduct PHP object injection attacks and execute arbitrary PHP code via a crafted serialized object.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Deserialization in n/a","id":"CVE-2016-3154","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"spip:spip","products":["spip:spip"],"type":"deserialization","year":"2016"},"n_packages":0,"n_references":3,"next":{"headline":"Information disclosure in n/a","id":"CVE-2016-3155"},"packages":[],"prev":{"headline":"Code injection in n/a","id":"CVE-2016-3153"},"products":["n/a"],"published":"2016-04-08","related":[{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2012-4331","kev_date_added":null,"published":"2012-08-14"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2008-5812","kev_date_added":null,"published":"2009-01-02"},{"cvss_score":9.8,"headline":"SPIP Bigup Multipart File Upload OS Command Injection","id":"CVE-2024-8517","kev_date_added":null,"published":"2024-09-06"},{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2023-24258","kev_date_added":null,"published":"2023-02-27"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2017-9736","kev_date_added":null,"published":"2017-06-17"},{"cvss_score":9.2,"headline":"SPIP \u003c 4.4.9 Insecure Deserialization","id":"CVE-2026-27475","kev_date_added":null,"published":"2026-02-19"}],"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":"2024-08-05","vendors":["n/a"]},"summary":"Remote attackers can execute arbitrary PHP code in SPIP CMS via crafted serialized objects in the encoder_contexte_ajax function.","url":"https://insights.sbomify.com/CVE-2016-3154/"}
