It can be exploited over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2011-4586 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-2011-4586/ (Markdown: https://insights.sbomify.com/CVE-2011-4586/index.md)","id":"CVE-2011-4586","markdown":"https://insights.sbomify.com/CVE-2011-4586/index.md","name":"CVE-2011-4586","record":{"aliases":["GHSA-5hc2-8542-698w"],"analysis":{"component_type":"web_application","fix_type":"upgrade","impacts":["other"],"network_reachable":"yes","non_default_config":false,"product_category":"Moodle LMS","requires_auth":"unknown","summary":"Remote attackers can inject HTTP headers and split responses in Moodle's calendar subsystem, potentially enabling cache poisoning or session fixation.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"moodle","vendor":"moodle"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:P/A:N","version":"2.0"},"cwes":[],"description":"CRLF injection vulnerability in calendar/set.php in the Calendar subsystem in Moodle 1.9.x before 1.9.15, 2.0.x before 2.0.6, and 2.1.x before 2.1.3 allows remote attackers to inject arbitrary HTTP headers and conduct HTTP response splitting attacks via unspecified vectors.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Other in n/a","id":"CVE-2011-4586","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"moodle:moodle","products":["moodle:moodle"],"type":"other","year":"2011"},"n_packages":0,"n_references":4,"next":{"headline":"Auth bypass in n/a","id":"CVE-2011-4587"},"packages":[],"prev":{"headline":"Weak cryptography in n/a","id":"CVE-2011-4585"},"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-07","vendors":["n/a"]},"summary":"Remote attackers can inject HTTP headers and split responses in Moodle's calendar subsystem, potentially enabling cache poisoning or session fixation.","url":"https://insights.sbomify.com/CVE-2011-4586/"}
