An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-28367 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- golang (Bitnami): affected all versions; fixed in 1.14.12, 1.15.5\n- toolchain (Go): affected all versions; fixed in 1.14.12, 1.15.5\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-2020-28367/ (Markdown: https://insights.sbomify.com/CVE-2020-28367/index.md)","id":"CVE-2020-28367","markdown":"https://insights.sbomify.com/CVE-2020-28367/index.md","name":"CVE-2020-28367","record":{"aliases":["BIT-golang-2020-28367","DEBIAN-CVE-2020-28367","GHSA-827f-m9xx-4cfw","GO-2022-0476","UBUNTU-CVE-2020-28367"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Go toolchain","requires_auth":"none","summary":"Attackers can execute arbitrary code during build time by injecting malicious gcc flags via cgo directives in Go projects.","user_interaction":"required","vuln_class":"code_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Go","cpe":[{"product":"go","vendor":"golang"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-94","name":"Improper Control of Generation of Code"}],"description":"Code injection in the go command with cgo before Go 1.14.12 and Go 1.15.5 allows arbitrary code execution at build time via malicious gcc flags specified via a #cgo directive.","ecosystems":["Bitnami","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":"Arbitrary code execution via the go command with cgo in cmd/go","id":"CVE-2020-28367","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"golang:go","products":["golang:go"],"type":"code_injection","year":"2020"},"n_packages":2,"n_references":6,"next":{"headline":"Information disclosure in n/a","id":"CVE-2020-28368"},"packages":[{"ecosystem":"Bitnami","fixed":["1.14.12","1.15.5"],"introduced":["0","1.15.0"],"last_affected":[],"package":"golang","purl":"pkg:bitnami/golang","source":"BIT-golang-2020-28367"},{"ecosystem":"Go","fixed":["1.14.12","1.15.5"],"introduced":["0","1.15.0-0"],"last_affected":[],"package":"toolchain","purl":"pkg:golang/toolchain","source":"GO-2022-0476"}],"prev":{"headline":"Arbitrary code execution in go command with cgo in cmd/go and cmd/cgo","id":"CVE-2020-28366"},"products":["cmd/go"],"published":"2020-11-18","related":[{"cvss_score":8.1,"headline":"Microsoft Windows CryptoAPI Spoofing","id":"CVE-2020-0601","kev_date_added":"2021-11-03","published":"2020-01-14"},{"cvss_score":9.8,"headline":"Missing bound checks can lead to memory corruption in safe Go in cmd/compile","id":"CVE-2026-27143","kev_date_added":null,"published":"2026-04-08"},{"cvss_score":9.8,"headline":"Unexpected behavior from Is methods for IPv4-mapped IPv6 addresses in net/netip","id":"CVE-2024-24790","kev_date_added":null,"published":"2024-06-05"},{"cvss_score":9.8,"headline":"Arbitrary code execution via go.mod toolchain directive in cmd/go","id":"CVE-2023-39320","kev_date_added":null,"published":"2023-09-08"},{"cvss_score":9.8,"headline":"Improper handling of JavaScript whitespace in html/template","id":"CVE-2023-24540","kev_date_added":null,"published":"2023-05-11"},{"cvss_score":9.8,"headline":"Backticks not treated as string delimiters in html/template","id":"CVE-2023-24538","kev_date_added":null,"published":"2023-04-06"},{"cvss_score":9.8,"headline":"Other in go/golang","id":"CVE-2012-2666","kev_date_added":null,"published":"2021-07-09"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"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":["Go toolchain"]},"summary":"Attackers can execute arbitrary code during build time by injecting malicious gcc flags via cgo directives in Go projects.","url":"https://insights.sbomify.com/CVE-2020-28367/"}
