An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2017-18393 in the wild and no public exploit code.\n\nAffected product: Cpanel Cpanel. 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-2017-18393/ (Markdown: https://insights.sbomify.com/CVE-2017-18393/index.md)","id":"CVE-2017-18393","markdown":"https://insights.sbomify.com/CVE-2017-18393/index.md","name":"CVE-2017-18393","record":{"aliases":["GHSA-h3cf-h9p9-v7f7"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"cPanel web hosting","requires_auth":"high_privilege","summary":"cPanel fails to block the reserved 'postmaster' username, potentially allowing attackers to intercept private email messages.","user_interaction":"not_required","vuln_class":"business_logic"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"cpanel","vendor":"cpanel"}],"cvss":{"score":2.7,"severity":"low","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"}],"description":"cPanel before 68.0.15 does not block a username of postmaster, which might allow reception of private e-mail (SEC-326).","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Business logic in n/a","id":"CVE-2017-18393","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cpanel:cpanel","products":["cpanel:cpanel"],"type":"business_logic","year":"2017"},"n_packages":0,"n_references":1,"next":{"headline":"Auth bypass in n/a","id":"CVE-2017-18394"},"packages":[],"prev":{"headline":"Business logic in n/a","id":"CVE-2017-18392"},"products":["n/a"],"published":"2019-08-02","related":[{"cvss_score":9.3,"headline":"WebPros cPanel \u0026 WHM and WP2 (WordPress Squared) Missing Authentication for Critical Function","id":"CVE-2026-41940","kev_date_added":"2026-04-30","published":"2026-04-29"},{"cvss_score":10,"headline":"guestbook.cgi in cPanel 5.0 allows remote attackers to execute arbitrary commands via the template parameter.","id":"CVE-2003-1425","kev_date_added":null,"published":"2007-10-20"},{"cvss_score":10,"headline":"Code injection in n/a","id":"CVE-2004-1769","kev_date_added":null,"published":"2005-03-10"},{"cvss_score":10,"headline":"Command injection in n/a","id":"CVE-2004-1770","kev_date_added":null,"published":"2005-03-10"},{"cvss_score":9.8,"headline":"Command injection in n/a","id":"CVE-2020-26098","kev_date_added":null,"published":"2020-09-25"},{"cvss_score":9.8,"headline":"Privilege escalation in n/a","id":"CVE-2020-26100","kev_date_added":null,"published":"2020-09-25"},{"cvss_score":9.8,"headline":"Hardcoded credentials in n/a","id":"CVE-2020-26101","kev_date_added":null,"published":"2020-09-25"}],"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":"cPanel fails to block the reserved 'postmaster' username, potentially allowing attackers to intercept private email messages.","url":"https://insights.sbomify.com/CVE-2017-18393/"}
