An attacker needs administrator access to exploit it, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2018-12100 in the wild and no public exploit code.\n\nAffected product: Sonatype Nexus Repository Manager. No package-level version data is available, so check the vendor advisory linked from the reference page.\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-2018-12100/ (Markdown: https://insights.sbomify.com/CVE-2018-12100/index.md)","id":"CVE-2018-12100","markdown":"https://insights.sbomify.com/CVE-2018-12100/index.md","name":"CVE-2018-12100","record":{"aliases":["GHSA-586j-7m8p-vv8r"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Nexus Repository Manager","requires_auth":"high_privilege","summary":"Cross-site scripting in the Administration UI allows attackers to execute scripts or hijack sessions, requiring an upgrade to Nexus Repository Manager.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"nexus_repository_manager","vendor":"sonatype"}],"cvss":{"score":4.8,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:R/S:C/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"Sonatype Nexus Repository Manager versions 3.x before 3.12.0 has XSS in multiple areas in the Administration UI.","ecosystems":[],"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":"Cross-site scripting in n/a","id":"CVE-2018-12100","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"sonatype:nexus_repository_manager","products":["sonatype:nexus_repository_manager"],"type":"xss","year":"2018"},"n_packages":0,"n_references":4,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2018-12101"},"packages":[],"prev":{"headline":"Grafana Cross-site Scripting (XSS)","id":"CVE-2018-12099"},"products":["n/a"],"published":"2018-06-11","related":[{"cvss_score":9.8,"headline":"Sonatype Nexus Repository Manager Incorrect Access Control","id":"CVE-2019-7238","kev_date_added":"2021-12-10","published":"2019-03-21"},{"cvss_score":9.8,"headline":"Hardcoded credentials in n/a","id":"CVE-2019-9629","kev_date_added":null,"published":"2019-07-08"},{"cvss_score":9.8,"headline":"Hardcoded credentials in n/a","id":"CVE-2017-17717","kev_date_added":null,"published":"2017-12-17"},{"cvss_score":9.4,"headline":"Nexus Repository 3 - Authenticated Remote Code Execution via Task Property Injection","id":"CVE-2026-3199","kev_date_added":null,"published":"2026-04-08"},{"cvss_score":9.2,"headline":"Nexus Repository 3 - Hardcoded Credential in Internal Database Component","id":"CVE-2026-5189","kev_date_added":null,"published":"2026-04-15"},{"cvss_score":8.9,"headline":"Nexus Repository 3 - Wildcard Privilege Update Self-Escalation to Administrator","id":"CVE-2026-17601","kev_date_added":null,"published":"2026-08-07"},{"cvss_score":8.8,"headline":"Code injection in n/a","id":"CVE-2020-15871","kev_date_added":null,"published":"2020-07-31"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":["n/a"]},"summary":"Cross-site scripting in the Administration UI allows attackers to execute scripts or hijack sessions, requiring an upgrade to Nexus Repository Manager.","url":"https://insights.sbomify.com/CVE-2018-12100/"}
