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-2022-41720 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- golang (Bitnami): affected all versions; fixed in 1.18.9, 1.19.4\n- stdlib (Go): affected all versions; fixed in 1.18.9, 1.19.4\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-2022-41720/ (Markdown: https://insights.sbomify.com/CVE-2022-41720/index.md)","id":"CVE-2022-41720","markdown":"https://insights.sbomify.com/CVE-2022-41720/index.md","name":"CVE-2022-41720","record":{"aliases":["AZL-79038","AZL-98604","BIT-golang-2022-41720","DEBIAN-CVE-2022-41720","GHSA-cvf9-g74c-vv79","GO-2022-1143","MINI-2h8p-5r8j-g483"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Go standard library","requires_auth":"none","summary":"Attackers can access restricted Windows device files or escape drive roots via crafted paths in Go's os.DirFS and http.Dir functions.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Go","cpe":[{"product":"go","vendor":"golang"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-22","name":"Improper Limitation of a Pathname to a Restricted Directory"}],"description":"On Windows, restricted files can be accessed via os.DirFS and http.Dir. The os.DirFS function and http.Dir type provide access to a tree of files rooted at a given directory. These functions permit access to Windows device files under that root. For example, os.DirFS(\"C:/tmp\").Open(\"COM1\") opens the COM1 device. Both os.DirFS and http.Dir only provide read-only filesystem access. In addition, on Windows, an os.DirFS for the directory (the root of the current drive) can permit a maliciously crafted path to escape from the drive and access any path on the system. With fix applied, the behavior of os.DirFS(\"\") has changed. Previously, an empty root was treated equivalently to \"/\", so os.DirFS(\"\").Open(\"tmp\") would open the path \"/tmp\". This now returns an error.","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":"Restricted file access on Windows in os and net/http","id":"CVE-2022-41720","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":"golang:go","products":["golang:go"],"type":"path_traversal","year":"2022"},"n_packages":2,"n_references":4,"next":{"headline":"Request smuggling due to improper request handling in golang.org/x/net/http2/h2c","id":"CVE-2022-41721"},"packages":[{"ecosystem":"Bitnami","fixed":["1.18.9","1.19.4"],"introduced":["0","1.19.0"],"last_affected":[],"package":"golang","purl":"pkg:bitnami/golang","source":"BIT-golang-2022-41720"},{"ecosystem":"Go","fixed":["1.18.9","1.19.4"],"introduced":["0","1.19.0-0"],"last_affected":[],"package":"stdlib","purl":"pkg:golang/stdlib","source":"GO-2022-1143"}],"prev":{"headline":"Panic in github.com/shamaton/msgpack/v2","id":"CVE-2022-41719"},"products":["net/http","os"],"published":"2022-12-07","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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2025-04-23","vendors":["Go standard library"]},"summary":"Attackers can access restricted Windows device files or escape drive roots via crafted paths in Go's os.DirFS and http.Dir functions.","url":"https://insights.sbomify.com/CVE-2022-41720/"}
