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-2011-1891 in the wild and no public exploit code.\n\nAffected product: Microsoft Sharepoint Foundation. 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-2011-1891/ (Markdown: https://insights.sbomify.com/CVE-2011-1891/index.md)","id":"CVE-2011-1891","markdown":"https://insights.sbomify.com/CVE-2011-1891/index.md","name":"CVE-2011-1891","record":{"aliases":["GHSA-2hw3-28v7-q78p"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"SharePoint Foundation","requires_auth":"none","summary":"Remote attackers can inject arbitrary web script via reflected XSS in SharePoint, requiring user interaction to execute malicious code.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"microsoft","cpe":[{"product":"sharepoint_foundation","vendor":"microsoft"},{"product":"sharepoint_services","vendor":"microsoft"}],"cvss":{"score":4.3,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/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":"Cross-site scripting (XSS) vulnerability in Microsoft Windows SharePoint Services 3.0 SP2, and SharePoint Foundation 2010 Gold and SP1, allows remote attackers to inject arbitrary web script or HTML via unspecified parameters in a request to a script, aka \"Contact Details Reflected XSS Vulnerability.\"","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":"Cross-site scripting in n/a","id":"CVE-2011-1891","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"microsoft:sharepoint_foundation","products":["microsoft:sharepoint_foundation"],"type":"xss","year":"2011"},"n_packages":0,"n_references":3,"next":{"headline":"XML external entity in n/a","id":"CVE-2011-1892"},"packages":[],"prev":{"headline":"Cross-site scripting in n/a","id":"CVE-2011-1890"},"products":["n/a"],"published":"2011-09-15","related":[{"cvss_score":9.3,"headline":"Privilege escalation in n/a","id":"CVE-2014-2816","kev_date_added":null,"published":"2014-08-12"},{"cvss_score":8.8,"headline":"Microsoft SharePoint Server Remote Code Execution Vulnerability","id":"CVE-2023-21742","kev_date_added":null,"published":"2023-01-10"},{"cvss_score":8.8,"headline":"Microsoft SharePoint Server Remote Code Execution Vulnerability","id":"CVE-2023-21744","kev_date_added":null,"published":"2023-01-10"},{"cvss_score":8.8,"headline":"Microsoft SharePoint Server Remote Code Execution Vulnerability","id":"CVE-2022-44690","kev_date_added":null,"published":"2022-12-13"},{"cvss_score":8.8,"headline":"Microsoft SharePoint Server Remote Code Execution Vulnerability","id":"CVE-2022-41036","kev_date_added":null,"published":"2022-10-11"},{"cvss_score":8.8,"headline":"Microsoft SharePoint Server Remote Code Execution Vulnerability","id":"CVE-2022-41037","kev_date_added":null,"published":"2022-10-11"},{"cvss_score":8.8,"headline":"Microsoft SharePoint Server Remote Code Execution Vulnerability","id":"CVE-2022-41038","kev_date_added":null,"published":"2022-10-11"}],"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":"2024-08-06","vendors":["n/a"]},"summary":"Remote attackers can inject arbitrary web script via reflected XSS in SharePoint, requiring user interaction to execute malicious code.","url":"https://insights.sbomify.com/CVE-2011-1891/"}
