Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-2091 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:ec2 (Maven): affected all versions; fixed in 1.48\n- org.jenkins-ci.plugins:ec2 (Maven): affected all versions; fixed in 1.48\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-2020-2091/ (Markdown: https://insights.sbomify.com/CVE-2020-2091/index.md)","id":"CVE-2020-2091","markdown":"https://insights.sbomify.com/CVE-2020-2091/index.md","name":"CVE-2020-2091","record":{"aliases":["GHSA-6hmm-77r2-h6hr"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins EC2 Plugin","requires_auth":"low_privilege","summary":"Attackers with read permissions can connect to arbitrary AWS URLs using stolen credentials due to missing permission checks in the Jenkins EC2 plugin.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"amazon_ec2","vendor":"jenkins"}],"cvss":{"score":8.1,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-862","name":"Missing Authorization"}],"description":"A missing permission check in Jenkins Amazon EC2 Plugin 1.47 and earlier allows attackers with Overall/Read permission to connect to an attacker-specified URL within the AWS region using attacker-specified credentials IDs obtained through another method.","ecosystems":["Maven"],"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":"Missing permission checks in Jenkins Amazon EC2 Plugin","id":"CVE-2020-2091","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"missing_authorization","year":"2020"},"n_packages":2,"n_references":1,"next":{"headline":"XXE vulnerability in Jenkins Robot Framework Plugin","id":"CVE-2020-2092"},"packages":[{"ecosystem":"Maven","fixed":["1.48"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:ec2","purl":null,"source":"GHSA-6hmm-77r2-h6hr"},{"ecosystem":"Maven","fixed":["1.48"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:ec2","purl":"pkg:maven/org.jenkins-ci.plugins/ec2","source":"GHSA-6hmm-77r2-h6hr"}],"prev":{"headline":"CSRF vulnerability in Jenkins Amazon EC2 Plugin","id":"CVE-2020-2090"},"products":["Jenkins Amazon EC2 Plugin"],"published":"2020-01-15","related":[{"cvss_score":8.8,"headline":"CSRF vulnerability in Jenkins Amazon EC2 Plugin","id":"CVE-2020-2090","kev_date_added":null,"published":"2020-01-15"},{"cvss_score":5.6,"headline":"Missing SSH host key validation in Jenkins Amazon EC2 Plugin","id":"CVE-2020-2185","kev_date_added":null,"published":"2020-05-06"},{"cvss_score":5.6,"headline":"Lack of SSL/TLS certificate and hostname validation in Amazon EC2 Plugin","id":"CVE-2020-2187","kev_date_added":null,"published":"2020-05-06"},{"cvss_score":4.3,"headline":"CSRF vulnerability in Amazon EC2 Plugin","id":"CVE-2020-2186","kev_date_added":null,"published":"2020-05-06"},{"cvss_score":4.3,"headline":"Users with Overall/Read access can enumerate credentials IDs in Amazon EC2 Plugin","id":"CVE-2020-2188","kev_date_added":null,"published":"2020-05-06"}],"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":"2024-08-04","vendors":["Jenkins project"]},"summary":"Attackers with read permissions can connect to arbitrary AWS URLs using stolen credentials due to missing permission checks in the Jenkins EC2 plugin.","url":"https://insights.sbomify.com/CVE-2020-2091/"}
