Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2020-2305 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.jenkins-ci.plugins:mercurial (Maven): affected all versions; fixed in 2.8.1\n- org.jenkins-ci.plugins:mercurial (Maven): affected all versions; fixed in 2.8.1\n- org.jenkins-ci.plugins:mercurial (Maven): affected from 2.10; fixed in 2.10.1\n- org.jenkins-ci.plugins:mercurial (Maven): affected from 2.10; fixed in 2.10.1\n- org.jenkins-ci.plugins:mercurial (Maven): affected from 2.11; fixed in 2.12\n- org.jenkins-ci.plugins:mercurial (Maven): affected from 2.11; fixed in 2.12\n- org.jenkins-ci.plugins:mercurial (Maven): affected from 2.9; fixed in 2.9.1\n- org.jenkins-ci.plugins:mercurial (Maven): affected from 2.9; fixed in 2.9.1\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-2020-2305/ (Markdown: https://insights.sbomify.com/CVE-2020-2305/index.md)","id":"CVE-2020-2305","markdown":"https://insights.sbomify.com/CVE-2020-2305/index.md","name":"CVE-2020-2305","record":{"aliases":["GHSA-x58r-wxc3-7pqr"],"analysis":{"component_type":"cms_plugin","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Jenkins Mercurial Plugin","requires_auth":"low_privilege","summary":"Attackers can exploit XML external entity vulnerabilities in the Jenkins Mercurial Plugin to read sensitive files or cause denial of service.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"jenkins","cpe":[{"product":"mercurial","vendor":"jenkins"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[],"description":"Jenkins Mercurial Plugin 2.11 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.","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":"XXE vulnerability in Jenkins Mercurial Plugin","id":"CVE-2020-2305","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Maven","product":null,"products":[],"type":"xxe","year":"2020"},"n_packages":8,"n_references":1,"next":{"headline":"Missing Authorization in Jenkins Mercurial Plugin","id":"CVE-2020-2306"},"packages":[{"ecosystem":"Maven","fixed":["2.8.1"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:mercurial","purl":null,"source":"GHSA-x58r-wxc3-7pqr"},{"ecosystem":"Maven","fixed":["2.8.1"],"introduced":["0"],"last_affected":[],"package":"org.jenkins-ci.plugins:mercurial","purl":"pkg:maven/org.jenkins-ci.plugins/mercurial","source":"GHSA-x58r-wxc3-7pqr"},{"ecosystem":"Maven","fixed":["2.10.1"],"introduced":["2.10"],"last_affected":[],"package":"org.jenkins-ci.plugins:mercurial","purl":null,"source":"GHSA-x58r-wxc3-7pqr"},{"ecosystem":"Maven","fixed":["2.10.1"],"introduced":["2.10"],"last_affected":[],"package":"org.jenkins-ci.plugins:mercurial","purl":"pkg:maven/org.jenkins-ci.plugins/mercurial","source":"GHSA-x58r-wxc3-7pqr"},{"ecosystem":"Maven","fixed":["2.12"],"introduced":["2.11"],"last_affected":[],"package":"org.jenkins-ci.plugins:mercurial","purl":null,"source":"GHSA-x58r-wxc3-7pqr"},{"ecosystem":"Maven","fixed":["2.12"],"introduced":["2.11"],"last_affected":[],"package":"org.jenkins-ci.plugins:mercurial","purl":"pkg:maven/org.jenkins-ci.plugins/mercurial","source":"GHSA-x58r-wxc3-7pqr"},{"ecosystem":"Maven","fixed":["2.9.1"],"introduced":["2.9"],"last_affected":[],"package":"org.jenkins-ci.plugins:mercurial","purl":null,"source":"GHSA-x58r-wxc3-7pqr"},{"ecosystem":"Maven","fixed":["2.9.1"],"introduced":["2.9"],"last_affected":[],"package":"org.jenkins-ci.plugins:mercurial","purl":"pkg:maven/org.jenkins-ci.plugins/mercurial","source":"GHSA-x58r-wxc3-7pqr"}],"prev":{"headline":"XXE vulnerability in Jenkins Subversion Plugin","id":"CVE-2020-2304"},"products":["Jenkins Mercurial Plugin"],"published":"2020-11-04","related":[{"cvss_score":7.5,"headline":"Path traversal in Jenkins Mercurial Plugin","id":"CVE-2022-30948","kev_date_added":null,"published":"2022-05-17"},{"cvss_score":5.3,"headline":"Webhook endpoint discloses job names to unauthorized users in Jenkins Mercurial Plugin","id":"CVE-2022-43410","kev_date_added":null,"published":"2022-10-19"},{"cvss_score":5.3,"headline":"Incorrect Authorization in Jenkins Mercurial Plugin","id":"CVE-2018-1000112","kev_date_added":null,"published":"2018-03-13"},{"cvss_score":4.3,"headline":"Missing Authorization in Jenkins Mercurial Plugin","id":"CVE-2020-2306","kev_date_added":null,"published":"2020-11-04"}],"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 can exploit XML external entity vulnerabilities in the Jenkins Mercurial Plugin to read sensitive files or cause denial of service.","url":"https://insights.sbomify.com/CVE-2020-2305/"}
