Easytest, published on 15 Oct 2021. Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-42336 in the wild and no public exploit code.\n\nAffected product: Huachu Digital Technology Co.,Ltd. Easytest. 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-2021-42336/ (Markdown: https://insights.sbomify.com/CVE-2021-42336/index.md)","id":"CVE-2021-42336","markdown":"https://insights.sbomify.com/CVE-2021-42336/index.md","name":"CVE-2021-42336","record":{"aliases":["GHSA-g2g9-w63f-6jrm"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Easytest web application","requires_auth":"low_privilege","summary":"Remote attackers can bypass permissions to access other users' and administrators' account information by crafting URL parameters in the learning history page.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"twcert","cpe":[{"product":"easytest_online_learning_test_platform","vendor":"huaju"}],"cvss":{"score":4.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-285","name":"Improper Authorization"}],"description":"The learning history page of the Easytest is vulnerable by permission bypass.
