Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-43578 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:squashtm-publisher-plugin (Maven): affected all versions up to 1.0.0; no fix listed\n- org.jenkins-ci.plugins:squashtm-publisher-plugin (Maven): affected all versions up to 1.0.0; no fix listed\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-2021-43578/ (Markdown: https://insights.sbomify.com/CVE-2021-43578/index.md)","id":"CVE-2021-43578","markdown":"https://insights.sbomify.com/CVE-2021-43578/index.md","name":"CVE-2021-43578","record":{"aliases":["GHSA-h648-gj34-5x4r"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_modify"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins plugin","requires_auth":"low_privilege","summary":"Attackers controlling Jenkins agents can overwrite arbitrary files on the controller with malicious JSON due to missing input validation in the Squash TM Publisher plugin.","user_interaction":"not_required","vuln_class":"path_traversal"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"squash_tm_publisher","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:N/I:H/A:H","version":"3.1"},"cwes":[],"description":"Jenkins Squash TM Publisher (Squash4Jenkins) Plugin 1.0.0 and earlier implements an agent-to-controller message that does not implement any validation of its input, allowing attackers able to control agent processes to replace arbitrary files on the Jenkins controller file system with an attacker-controlled JSON string.","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":false,"headline":"Agent-to-controller security bypass in Jenkins Squash TM Publisher (Squash4Jenkins) Plugin allows writing arbitrary files","id":"CVE-2021-43578","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"path_traversal","year":"2021"},"n_packages":2,"n_references":2,"next":{"headline":"Memory corruption in n/a","id":"CVE-2021-43579"},"packages":[{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["1.0.0"],"package":"org.jenkins-ci.plugins:squashtm-publisher-plugin","purl":null,"source":"GHSA-h648-gj34-5x4r"},{"ecosystem":"Maven","fixed":[],"introduced":["0"],"last_affected":["1.0.0"],"package":"org.jenkins-ci.plugins:squashtm-publisher-plugin","purl":"pkg:maven/org.jenkins-ci.plugins/squashtm-publisher-plugin","source":"GHSA-h648-gj34-5x4r"}],"prev":{"headline":"XXE vulnerability in Jenkins OWASP Dependency-Check Plugin","id":"CVE-2021-43577"},"products":["Jenkins Squash TM Publisher (Squash4Jenkins) Plugin"],"published":"2021-11-12","related":[{"cvss_score":6.5,"headline":"Squash TM Publisher (Squash4Jenkins) Plugin stores passwords stored in plain text","id":"CVE-2022-34213","kev_date_added":null,"published":"2022-06-22"}],"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":"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 controlling Jenkins agents can overwrite arbitrary files on the controller with malicious JSON due to missing input validation in the Squash TM Publisher plugin.","url":"https://insights.sbomify.com/CVE-2021-43578/"}
