Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2011-4590 in the wild and no public exploit code.\n\nAffected product: Moodle Moodle. 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-2011-4590/ (Markdown: https://insights.sbomify.com/CVE-2011-4590/index.md)","id":"CVE-2011-4590","markdown":"https://insights.sbomify.com/CVE-2011-4590/index.md","name":"CVE-2011-4590","record":{"aliases":["GHSA-p586-c547-p893"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Moodle LMS","requires_auth":"low_privilege","summary":"Authenticated users can bypass maintenance mode and account restrictions to access Moodle web services.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"moodle","vendor":"moodle"}],"cvss":{"score":4,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:S/C:N/I:P/A:N","version":"2.0"},"cwes":[{"id":"CWE-287","name":"Improper Authentication"}],"description":"The web services implementation in Moodle 2.0.x before 2.0.6 and 2.1.x before 2.1.3 does not properly consider the maintenance-mode state and account attributes during login attempts, which allows remote authenticated users to bypass intended access restrictions by connecting to a webservice server.","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":"Auth bypass in n/a","id":"CVE-2011-4590","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"moodle:moodle","products":["moodle:moodle"],"type":"auth_bypass","year":"2011"},"n_packages":0,"n_references":3,"next":{"headline":"Cross-site scripting in n/a","id":"CVE-2011-4591"},"packages":[],"prev":{"headline":"Missing authorization in n/a","id":"CVE-2011-4589"},"products":["n/a"],"published":"2012-07-20","related":[{"cvss_score":10,"headline":"File upload in n/a","id":"CVE-2006-4935","kev_date_added":null,"published":"2006-09-23"},{"cvss_score":10,"headline":"Moodle does not properly validate module instance id","id":"CVE-2006-4936","kev_date_added":null,"published":"2006-09-23"},{"cvss_score":10,"headline":"Unknown \"front page vulnerability with Moodle servers\" for Moodle before 1.3.2 has unknown impact and attack vectors.","id":"CVE-2004-2233","kev_date_added":null,"published":"2005-07-17"},{"cvss_score":10,"headline":"Cross-site scripting in n/a","id":"CVE-2004-2235","kev_date_added":null,"published":"2005-07-17"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2004-2236","kev_date_added":null,"published":"2005-07-17"},{"cvss_score":10,"headline":"Unknown vulnerability in Moodle before 1.3.4 has unknown impact and attack vectors, related to \"strings in Moodle texts.\"","id":"CVE-2004-2237","kev_date_added":null,"published":"2005-07-17"},{"cvss_score":10,"headline":"Multiple unknown vulnerabilities in Moodle before 1.5.1 have unknown impact and attack vectors.","id":"CVE-2005-2247","kev_date_added":null,"published":"2005-07-12"}],"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":"2024-08-07","vendors":["n/a"]},"summary":"Authenticated users can bypass maintenance mode and account restrictions to access Moodle web services.","url":"https://insights.sbomify.com/CVE-2011-4590/"}
