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-2018-16873 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- toolchain (Go): affected all versions; fixed in 1.10.6, 1.11.3\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-2018-16873/ (Markdown: https://insights.sbomify.com/CVE-2018-16873/index.md)","id":"CVE-2018-16873","markdown":"https://insights.sbomify.com/CVE-2018-16873/index.md","name":"CVE-2018-16873","record":{"aliases":["GHSA-q6pp-3q54-qw37","GO-2022-0189","UBUNTU-CVE-2018-16873"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"Go toolchain","requires_auth":"none","summary":"Attackers can execute arbitrary commands on the developer's machine by tricking the Go toolchain into treating a malicious directory as a Git repository.","user_interaction":"required","vuln_class":"command_injection"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"go","vendor":"golang"},{"product":"backports_sle","vendor":"opensuse"},{"product":"leap","vendor":"opensuse"},{"product":"linux_enterprise_server","vendor":"suse"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"In Go before 1.10.6 and 1.11.x before 1.11.3, the \"go get\" command is vulnerable to remote code execution when executed with the -u flag and the import path of a malicious Go package, or a package that imports it directly or indirectly. Specifically, it is only vulnerable in GOPATH mode, but not in module mode (the distinction is documented at https://golang.org/cmd/go/#hdr-Module_aware_go_get). Using custom domains, it's possible to arrange things so that a Git repository is cloned to a folder named \".git\" by using a vanity import path that ends with \"/.git\". If the Git repository root contains a \"HEAD\" file, a \"config\" file, an \"objects\" directory, a \"refs\" directory, with some work to ensure the proper ordering of operations, \"go get -u\" can be tricked into considering the parent directory as a repository root, and running Git commands on it. That will use the \"config\" file in the original Git repository root for its configuration, and if that config file contains malicious commands, they will execute on the system running \"go get -u\".","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":"Command injection in golang","id":"CVE-2018-16873","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":"debian:debian_linux","products":["debian:debian_linux","golang:go","opensuse:backports_sle","opensuse:leap","suse:linux_enterprise_server"],"type":"command_injection","year":"2018"},"n_packages":1,"n_references":12,"next":{"headline":"Path traversal in golang","id":"CVE-2018-16874"},"packages":[{"ecosystem":"Go","fixed":["1.10.6","1.11.3"],"introduced":["0","1.11.0-0"],"last_affected":[],"package":"toolchain","purl":"pkg:golang/toolchain","source":"GO-2022-0189"}],"prev":{"headline":"Race condition in QEMU:","id":"CVE-2018-16872"},"products":["golang"],"published":"2018-12-14","related":[{"cvss_score":10,"headline":"ProFTPD Improper Access Control","id":"CVE-2015-3306","kev_date_added":"2026-10-08","published":"2015-05-18"},{"cvss_score":9.9,"headline":"RoundCube Webmail Deserialization of Untrusted Data","id":"CVE-2025-49113","kev_date_added":"2026-02-20","published":"2025-06-02"},{"cvss_score":9.8,"headline":"GNU InetUtils Argument Injection","id":"CVE-2026-24061","kev_date_added":"2026-01-26","published":"2026-01-21"},{"cvss_score":9.8,"headline":"Linux Kernel Improper Check for Unusual or Exceptional Conditions","id":"CVE-2025-39682","kev_date_added":"2026-09-18","published":"2025-09-05"},{"cvss_score":9.8,"headline":"Mozilla Firefox Use-After-Free","id":"CVE-2024-9680","kev_date_added":"2024-10-15","published":"2024-10-09"},{"cvss_score":9.8,"headline":"RARLAB UnRAR Directory Traversal","id":"CVE-2022-30333","kev_date_added":"2022-08-09","published":"2022-05-09"},{"cvss_score":9.8,"headline":"Roundcube Webmail SQL Injection","id":"CVE-2021-44026","kev_date_added":"2023-06-22","published":"2021-11-19"}],"sources":[{"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":"2024-08-05","vendors":["[UNKNOWN]"]},"summary":"Attackers can execute arbitrary commands on the developer's machine by tricking the Go toolchain into treating a malicious directory as a Git repository.","url":"https://insights.sbomify.com/CVE-2018-16873/"}
