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-2021-38753 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-2021-38753/ (Markdown: https://insights.sbomify.com/CVE-2021-38753/index.md)","id":"CVE-2021-38753","markdown":"https://insights.sbomify.com/CVE-2021-38753/index.md","name":"CVE-2021-38753","record":{"aliases":["GHSA-63q8-3w8v-3263"],"analysis":{"component_type":"web_application","fix_type":"no_fix_stated","impacts":["code_execution","privilege_escalation"],"network_reachable":"yes","non_default_config":false,"product_category":"Simple Image Gallery Web App","requires_auth":"none","summary":"Attackers can upload malicious web shells to the Simple Image Gallery Web App to execute arbitrary code and gain unauthorized server access.","user_interaction":"not_required","vuln_class":"file_upload"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"simple_image_gallery_web_app","vendor":"simple_image_gallery_web_app_project"}],"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-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"An unrestricted file upload on Simple Image Gallery Web App can be exploited to upload a web shell and executed to gain unauthorized access to the server hosting the web app.","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":"File upload in n/a","id":"CVE-2021-38753","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"file_upload","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"SQL injection in n/a","id":"CVE-2021-38754"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2021-38752"},"products":["n/a"],"published":"2021-08-16","related":[{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2023-27040","kev_date_added":null,"published":"2023-03-16"},{"cvss_score":8.8,"headline":"SQL injection in n/a","id":"CVE-2021-38819","kev_date_added":null,"published":"2022-11-16"}],"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 upload malicious web shells to the Simple Image Gallery Web App to execute arbitrary code and gain unauthorized server access.","url":"https://insights.sbomify.com/CVE-2021-38753/"}
