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-2018-20303 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- gogs.io/gogs (Go): affected all versions; fixed in 0.11.80-0.20181218063808-ff93d9dbda5c\n- gogs.io/gogs (Go): affected all versions; fixed in 0.11.80-0.20181218063808-ff93d9dbda5c\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-2018-20303/ (Markdown: https://insights.sbomify.com/CVE-2018-20303/index.md)","id":"CVE-2018-20303","markdown":"https://insights.sbomify.com/CVE-2018-20303/index.md","name":"CVE-2018-20303","record":{"aliases":["GHSA-9hxg-w7qf-hh93"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Gogs Git server","requires_auth":"none","summary":"An attacker can exploit a directory traversal flaw in Gogs to create arbitrary files on the server via the file-upload functionality.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"gogs","vendor":"gogs"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N","version":"3.0"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"In pkg/tool/path.go in Gogs before 0.11.82.1218, a directory traversal in the file-upload functionality can allow an attacker to create a file under data/sessions on the server, a similar issue to CVE-2018-18925.","ecosystems":["Go"],"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":"Gogs Directory Traversal","id":"CVE-2018-20303","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"path_traversal","year":"2018"},"n_packages":2,"n_references":3,"next":{"headline":"Denial of service in n/a","id":"CVE-2018-20304"},"packages":[{"ecosystem":"Go","fixed":["0.11.80-0.20181218063808-ff93d9dbda5c"],"introduced":["0"],"last_affected":[],"package":"gogs.io/gogs","purl":null,"source":"GHSA-9hxg-w7qf-hh93"},{"ecosystem":"Go","fixed":["0.11.80-0.20181218063808-ff93d9dbda5c"],"introduced":["0"],"last_affected":[],"package":"gogs.io/gogs","purl":"pkg:golang/gogs.io/gogs","source":"GHSA-9hxg-w7qf-hh93"}],"prev":{"headline":"Cross-site Scripting in xain","id":"CVE-2018-20302"},"products":["n/a"],"published":"2018-12-20","related":[{"cvss_score":8.7,"headline":"Gogs Path Traversal","id":"CVE-2025-8110","kev_date_added":"2026-01-12","published":"2025-12-10"},{"cvss_score":10,"headline":"Gogs deletion of internal files allows remote command execution","id":"CVE-2024-56731","kev_date_added":null,"published":"2025-06-24"},{"cvss_score":10,"headline":"Remote Command Execution in gogs/gogs","id":"CVE-2022-1884","kev_date_added":null,"published":"2024-11-15"},{"cvss_score":10,"headline":"OS Command Injection in gogs/gogs","id":"CVE-2022-1986","kev_date_added":null,"published":"2022-06-09"},{"cvss_score":10,"headline":"Path Traversal in gogs/gogs","id":"CVE-2022-1992","kev_date_added":null,"published":"2022-06-08"},{"cvss_score":9.9,"headline":"Duplicate Advisory: github.com/gogs/gogs affected by CVE-2024-39930","id":"CVE-2024-39930","kev_date_added":null,"published":"2024-07-04"},{"cvss_score":9.9,"headline":"Duplicate Advisory: Gogs allows deletion of internal files","id":"CVE-2024-39931","kev_date_added":null,"published":"2024-07-04"}],"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":"2024-08-05","vendors":["n/a"]},"summary":"An attacker can exploit a directory traversal flaw in Gogs to create arbitrary files on the server via the file-upload functionality.","url":"https://insights.sbomify.com/CVE-2018-20303/"}
