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-2016-3953 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- web2py (PyPI): affected all versions; fixed in 2.14.2\n- web2py (PyPI): affected all versions; fixed in 2.14.2\n- web2py (PyPI): affected all versions; fixed in 2.14.2\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-2016-3953/ (Markdown: https://insights.sbomify.com/CVE-2016-3953/index.md)","id":"CVE-2016-3953","markdown":"https://insights.sbomify.com/CVE-2016-3953/index.md","name":"CVE-2016-3953","record":{"aliases":["GHSA-q2rq-qgcf-m22w","PYSEC-2026-570","UBUNTU-CVE-2016-3953"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"web2py framework","requires_auth":"none","summary":"Remote attackers can execute arbitrary code in the web2py sample application due to a hardcoded encryption key used in session connections.","user_interaction":"not_required","vuln_class":"hardcoded_credentials"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"web2py","vendor":"web2py"}],"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-798","name":"Use of Hard-coded Credentials"}],"description":"The sample web application in web2py before 2.14.2 might allow remote attackers to execute arbitrary code via vectors involving use of a hardcoded encryption key when calling the session.connect function.","ecosystems":["PyPI"],"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":"web2py remote code execution via hardcoded encryption key in session.connect function","id":"CVE-2016-3953","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"hardcoded_credentials","year":"2016"},"n_packages":3,"n_references":3,"next":{"headline":"web2py exposure of sensitive information","id":"CVE-2016-3954"},"packages":[{"ecosystem":"PyPI","fixed":["2.14.2"],"introduced":["0"],"last_affected":[],"package":"web2py","purl":null,"source":"GHSA-q2rq-qgcf-m22w"},{"ecosystem":"PyPI","fixed":["2.14.2"],"introduced":["0"],"last_affected":[],"package":"web2py","purl":"pkg:pypi/web2py","source":"GHSA-q2rq-qgcf-m22w"},{"ecosystem":"PyPI","fixed":["2.14.2"],"introduced":["0"],"last_affected":[],"package":"web2py","purl":"pkg:pypi/web2py","source":"PYSEC-2026-570"}],"prev":{"headline":"Information disclosure in n/a","id":"CVE-2016-3952"},"products":["n/a"],"published":"2018-02-06","related":[{"cvss_score":9.8,"headline":"Command injection in web2py","id":"CVE-2023-45158","kev_date_added":null,"published":"2023-10-16"},{"cvss_score":9.8,"headline":"Deserialization in n/a","id":"CVE-2016-3957","kev_date_added":null,"published":"2018-02-06"},{"cvss_score":9.8,"headline":"web2py is vulnerable to password brute-force attack","id":"CVE-2016-10321","kev_date_added":null,"published":"2017-04-10"},{"cvss_score":8.8,"headline":"Web2py Cross-Site Request Forgery vulnerability","id":"CVE-2016-4808","kev_date_added":null,"published":"2017-01-11"},{"cvss_score":7.8,"headline":"Information disclosure in n/a","id":"CVE-2016-3952","kev_date_added":null,"published":"2018-02-06"},{"cvss_score":7.5,"headline":"Path traversal in n/a","id":"CVE-2016-4806","kev_date_added":null,"published":"2017-01-11"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"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":"Remote attackers can execute arbitrary code in the web2py sample application due to a hardcoded encryption key used in session connections.","url":"https://insights.sbomify.com/CVE-2016-3953/"}
