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-2021-44550 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- edu.stanford.nlp:stanford-corenlp (Maven): affected all versions; fixed in 4.4.0\n- edu.stanford.nlp:stanford-corenlp (Maven): affected all versions; fixed in 4.4.0\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-2021-44550/ (Markdown: https://insights.sbomify.com/CVE-2021-44550/index.md)","id":"CVE-2021-44550","markdown":"https://insights.sbomify.com/CVE-2021-44550/index.md","name":"CVE-2021-44550","record":{"aliases":["GHSA-x2p8-rgfm-qw3v"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"CoreNLP Java library","requires_auth":"none","summary":"Attackers can bypass access controls in the CoreNLP NERServlet classifier, potentially accessing restricted functionality without proper authorization.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"corenlp","vendor":"stanford"}],"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-74","name":"Improper Neutralization of Special Elements in Output Used by a Downstream Component"}],"description":"An Incorrect Access Control vulnerability exists in CoreNLP 4.3.2 via the classifier in NERServlet.java (lines 158 and 159).","ecosystems":["Maven"],"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":"Access Control vulnerability within CoreNLP","id":"CVE-2021-44550","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"missing_authorization","year":"2021"},"n_packages":2,"n_references":1,"next":{"headline":"Information disclosure in n/a","id":"CVE-2021-44554"},"packages":[{"ecosystem":"Maven","fixed":["4.4.0"],"introduced":["0"],"last_affected":[],"package":"edu.stanford.nlp:stanford-corenlp","purl":null,"source":"GHSA-x2p8-rgfm-qw3v"},{"ecosystem":"Maven","fixed":["4.4.0"],"introduced":["0"],"last_affected":[],"package":"edu.stanford.nlp:stanford-corenlp","purl":"pkg:maven/edu.stanford.nlp/stanford-corenlp","source":"GHSA-x2p8-rgfm-qw3v"}],"prev":{"headline":"SMTPS server hostname not checked when making TLS connection to SMTPS server","id":"CVE-2021-44549"},"products":["n/a"],"published":"2022-02-23","related":[{"cvss_score":9.8,"headline":"Improper Restriction of XML External Entity Reference in stanfordnlp/corenlp","id":"CVE-2021-3878","kev_date_added":null,"published":"2021-10-15"},{"cvss_score":8.6,"headline":"Improper Restriction of XML External Entity Reference in stanfordnlp/corenlp","id":"CVE-2021-3869","kev_date_added":null,"published":"2021-10-19"},{"cvss_score":6.1,"headline":"Improper Restriction of XML External Entity Reference in stanfordnlp/corenlp","id":"CVE-2022-0198","kev_date_added":null,"published":"2022-01-13"},{"cvss_score":4.7,"headline":"Improper Restriction of XML External Entity Reference in stanfordnlp/corenlp","id":"CVE-2022-0239","kev_date_added":null,"published":"2022-01-17"}],"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":"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 bypass access controls in the CoreNLP NERServlet classifier, potentially accessing restricted functionality without proper authorization.","url":"https://insights.sbomify.com/CVE-2021-44550/"}
