An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2003-0521 exists.\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-2003-0521/ (Markdown: https://insights.sbomify.com/CVE-2003-0521/index.md)","id":"CVE-2003-0521","markdown":"https://insights.sbomify.com/CVE-2003-0521/index.md","name":"CVE-2003-0521","record":{"aliases":["GHSA-g78q-qwhg-6p5x"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["privilege_escalation","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"cPanel web hosting","requires_auth":"none","summary":"Remote attackers can inject scripts via URLs logged in cPanel, potentially gaining administrator privileges through reflected XSS in error or visitor logs.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"cpanel","vendor":"cpanel"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[],"description":"Cross-site scripting (XSS) vulnerability in cPanel 6.4.2 allows remote attackers to insert arbitrary HTML and possibly gain cPanel administrator privileges via script in a URL that is logged but not properly quoted when displayed via the (1) Error Log or (2) Latest Visitors screens.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2003-07-07","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2003-07-07","kind":"exploitdb","ref":"22874","stars":null,"title":"CPanel 5.0/5.3/6.x - Admin Interface HTML Injection"}],"tier":"weaponised"},"has_fix":null,"headline":"Cross-site scripting in n/a","id":"CVE-2003-0521","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cpanel:cpanel","products":["cpanel:cpanel"],"type":"xss","year":"2003"},"n_packages":0,"n_references":1,"next":{"headline":"SQL injection in n/a","id":"CVE-2003-0522"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2003-0520"},"products":["n/a"],"published":"2003-07-10","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":"FIRST CVSS licence","name":"CVSS (FIRST)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-08","vendors":["n/a"]},"summary":"Remote attackers can inject scripts via URLs logged in cPanel, potentially gaining administrator privileges through reflected XSS in error or visitor logs.","url":"https://insights.sbomify.com/CVE-2003-0521/"}
