Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2020-29135 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-2020-29135/ (Markdown: https://insights.sbomify.com/CVE-2020-29135/index.md)","id":"CVE-2020-29135","markdown":"https://insights.sbomify.com/CVE-2020-29135/index.md","name":"CVE-2020-29135","record":{"aliases":["GHSA-vq9w-f7pp-xwj5"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"cPanel control panel","requires_auth":"low_privilege","summary":"Attackers can inject URL parameters in cPanel, potentially enabling phishing or bypassing security controls.","user_interaction":"required","vuln_class":"open_redirect"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"cpanel","vendor":"cpanel"}],"cvss":{"score":4.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-838","name":"Inappropriate Encoding for Output Context"}],"description":"cPanel before 90.0.17 has multiple instances of URL parameter injection (SEC-567).","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":"Open redirect in n/a","id":"CVE-2020-29135","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"cpanel:cpanel","products":["cpanel:cpanel"],"type":"open_redirect","year":"2020"},"n_packages":0,"n_references":1,"next":{"headline":"Security feature bypass in n/a","id":"CVE-2020-29136"},"packages":[],"prev":{"headline":"Path traversal in n/a","id":"CVE-2020-29134"},"products":["n/a"],"published":"2020-11-27","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":"2024-08-04","vendors":["n/a"]},"summary":"Attackers can inject URL parameters in cPanel, potentially enabling phishing or bypassing security controls.","url":"https://insights.sbomify.com/CVE-2020-29135/"}
