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-2020-21726 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-2020-21726/ (Markdown: https://insights.sbomify.com/CVE-2020-21726/index.md)","id":"CVE-2020-21726","markdown":"https://insights.sbomify.com/CVE-2020-21726/index.md","name":"CVE-2020-21726","record":{"aliases":["GHSA-48gx-cwj6-6p4c"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"OpenSNS CMS","requires_auth":"none","summary":"Attackers can exploit a blind SQL injection in OpenSNS to read sensitive database information via the cid parameter.","user_interaction":"not_required","vuln_class":"sql_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"opensns","vendor":"opensns"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-89","name":"Improper Neutralization of Special Elements used in an SQL Command"}],"description":"OpenSNS v6.1.0 contains a blind SQL injection vulnerability in /Controller/ChinaCityController.class.php via the cid parameter.","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":"SQL injection in n/a","id":"CVE-2020-21726","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"sql_injection","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2020-21729"},"packages":[],"prev":{"headline":"SQL injection in n/a","id":"CVE-2020-21725"},"products":["n/a"],"published":"2021-10-07","related":[{"cvss_score":9.8,"headline":"SQL injection in n/a","id":"CVE-2020-21725","kev_date_added":null,"published":"2021-10-07"},{"cvss_score":8.8,"headline":"SQL injection in n/a","id":"CVE-2019-14266","kev_date_added":null,"published":"2019-07-25"}],"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":"Attackers can exploit a blind SQL injection in OpenSNS to read sensitive database information via the cid parameter.","url":"https://insights.sbomify.com/CVE-2020-21726/"}
