Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-34257 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- wpanel/wpanel4-cms (Packagist): affected all versions up to 4.3.1; no fix listed\n- wpanel/wpanel4-cms (Packagist): affected all versions up to 4.3.1; no fix listed\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-2021-34257/ (Markdown: https://insights.sbomify.com/CVE-2021-34257/index.md)","id":"CVE-2021-34257","markdown":"https://insights.sbomify.com/CVE-2021-34257/index.md","name":"CVE-2021-34257","record":{"aliases":["GHSA-vhgr-gfx3-fg37"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"WPanel CMS","requires_auth":"low_privilege","summary":"Attackers can execute arbitrary code by uploading malicious PHP files to various image upload fields in WPanel.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"wpanel_cms","vendor":"wpanel_cms_project"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"Multiple Remote Code Execution (RCE) vulnerabilities exist in WPanel 4 4.3.1 and below via a malicious PHP file upload to (1) Dashboard's Avatar image, (2) Posts Folder image, (3) Pages Folder image and (4) Gallery Folder image.","ecosystems":["Packagist"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Unrestricted Upload of File with Dangerous Type in WPanel 4","id":"CVE-2021-34257","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Packagist","product":null,"products":[],"type":"file_upload","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"Memory corruption in n/a","id":"CVE-2021-34259"},"packages":[{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":["4.3.1"],"package":"wpanel/wpanel4-cms","purl":null,"source":"GHSA-vhgr-gfx3-fg37"},{"ecosystem":"Packagist","fixed":[],"introduced":["0"],"last_affected":["4.3.1"],"package":"wpanel/wpanel4-cms","purl":"pkg:composer/wpanel/wpanel4-cms","source":"GHSA-vhgr-gfx3-fg37"}],"prev":{"headline":"Open redirect in n/a","id":"CVE-2021-34254"},"products":["n/a"],"published":"2022-03-31","related":[],"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 execute arbitrary code by uploading malicious PHP files to various image upload fields in WPanel.","url":"https://insights.sbomify.com/CVE-2021-34257/"}
