An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-28337 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- microweber/microweber (Packagist): affected all versions; fixed in 1.2.3\n- microweber/microweber (Packagist): affected all versions; fixed in 1.2.3\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-2020-28337/ (Markdown: https://insights.sbomify.com/CVE-2020-28337/index.md)","id":"CVE-2020-28337","markdown":"https://insights.sbomify.com/CVE-2020-28337/index.md","name":"CVE-2020-28337","record":{"aliases":["GHSA-pqcf-v8v5-jmcg"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Microweber CMS","requires_auth":"high_privilege","summary":"An authenticated administrator can achieve remote code execution by uploading a malicious ZIP file with path traversal sequences and restoring it.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"microweber","vendor":"microweber"}],"cvss":{"score":7.2,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"A directory traversal issue in the Utils/Unzip module in Microweber through 1.1.20 allows an authenticated attacker to gain remote code execution via the backup restore feature.
