An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2011-4940 in the wild and no public exploit code.\n\nAffected product: Python Python. 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-2011-4940/ (Markdown: https://insights.sbomify.com/CVE-2011-4940/index.md)","id":"CVE-2011-4940","markdown":"https://insights.sbomify.com/CVE-2011-4940/index.md","name":"CVE-2011-4940","record":{"aliases":["AZL-109590","CVE-2012-2639","DEBIAN-CVE-2011-4940","GHSA-cr6h-6cqx-mw3f","PSF-2012-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Python standard library","requires_auth":"none","summary":"Remote attackers can execute cross-site scripting attacks against Internet Explorer 7 via UTF-7 encoding due to missing charset parameters in directory listings.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"python","vendor":"python"}],"cvss":{"score":2.6,"severity":"low","source":"nvd","vector":"AV:N/AC:H/Au:N/C:N/I:P/A:N","version":"2.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The list_directory function in Lib/SimpleHTTPServer.py in SimpleHTTPServer in Python before 2.5.6c1, 2.6.x before 2.6.7 rc2, and 2.7.x before 2.7.2 does not place a charset parameter in the Content-Type HTTP header, which makes it easier for remote attackers to conduct cross-site scripting (XSS) attacks against Internet Explorer 7 via UTF-7 encoding.","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":"Cross-site scripting in n/a","id":"CVE-2011-4940","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"python:python","products":["python:python"],"type":"xss","year":"2011"},"n_packages":0,"n_references":12,"next":{"headline":"Piwik (now Matomo) Vulnerable to Arbitrary Code Execution","id":"CVE-2011-4941"},"packages":[],"prev":{"headline":"Null dereference in n/a","id":"CVE-2011-4939"},"products":["n/a"],"published":"2012-06-27","related":[{"cvss_score":10,"headline":"Integer overflow in n/a","id":"CVE-2008-5031","kev_date_added":null,"published":"2008-11-10"},{"cvss_score":9.8,"headline":"Path traversal in n/a","id":"CVE-2014-4650","kev_date_added":null,"published":"2020-02-20"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2016-5636","kev_date_added":null,"published":"2016-09-02"},{"cvss_score":9.8,"headline":"Path traversal in n/a","id":"CVE-2007-4559","kev_date_added":null,"published":"2007-08-28"},{"cvss_score":8.8,"headline":"Command injection in n/a","id":"CVE-2017-17522","kev_date_added":null,"published":"2017-12-14"},{"cvss_score":8.7,"headline":"Incremental HTMLParser feed() allows CPU-exhaustion DoS via repeated unterminated markup declarations","id":"CVE-2026-15308","kev_date_added":null,"published":"2026-07-09"},{"cvss_score":7.8,"headline":"Privilege escalation in n/a","id":"CVE-2019-13404","kev_date_added":null,"published":"2019-07-08"}],"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":"Remote attackers can execute cross-site scripting attacks against Internet Explorer 7 via UTF-7 encoding due to missing charset parameters in directory listings.","url":"https://insights.sbomify.com/CVE-2011-4940/"}
