An attacker needs administrator access to exploit it, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2021-27781 in the wild and no public exploit code.\n\nAffected product: HCL BigFix Mobile / Modern Client Management. 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-2021-27781/ (Markdown: https://insights.sbomify.com/CVE-2021-27781/index.md)","id":"CVE-2021-27781","markdown":"https://insights.sbomify.com/CVE-2021-27781/index.md","name":"CVE-2021-27781","record":{"aliases":["GHSA-2r44-78ff-wqc3"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"HCL BigFix Mobile","requires_auth":"high_privilege","summary":"A stored cross-site scripting vulnerability allows attackers to inject scripts that can steal cookies or session data from users of HCL BigFix Mobile.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"HCL","cpe":[{"product":"bigfix_mobile","vendor":"hcltech"},{"product":"modern_client_management","vendor":"hcltech"}],"cvss":{"score":6.6,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"The Master operator may be able to embed script tag in HTML with alert pop-up display cookie.","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":"HCL BigFix Mobile / Modern Client Management is vulnerable to stored cross-site scripting","id":"CVE-2021-27781","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"HCL BigFix Mobile / Modern Client Management Server passwords are susceptible to a brute-force attack","id":"CVE-2021-27782"},"packages":[],"prev":{"headline":"HCL BigFix Mobile / Modern Client Management is vulnerable to unauthenticated XML interaction","id":"CVE-2021-27780"},"products":["HCL BigFix Mobile / Modern Client Management"],"published":"2022-05-27","related":[{"cvss_score":6.8,"headline":"HCL BigFix Mobile / Modern Client Management is vulnerable to sensitive information exposure","id":"CVE-2021-27783","kev_date_added":null,"published":"2022-05-25"},{"cvss_score":6.6,"headline":"HCL BigFix Mobile can be affected by a cross-site scripting (XSS) vulnerability","id":"CVE-2023-28014","kev_date_added":null,"published":"2023-07-26"},{"cvss_score":6.5,"headline":"HCL BigFix Modern Client Management (MCM) is affected by an insecure Content Security Policy (CSP)","id":"CVE-2025-0276","kev_date_added":null,"published":"2025-10-16"},{"cvss_score":6.5,"headline":"HCL BigFix Mobile is affected by an insecure Content Security Policy (CSP)","id":"CVE-2025-0277","kev_date_added":null,"published":"2025-10-16"},{"cvss_score":5.4,"headline":"HCL BigFix Mobile can be affected by a command injection vulnerability","id":"CVE-2023-28012","kev_date_added":null,"published":"2023-07-26"},{"cvss_score":5.4,"headline":"HCL BigFix Mobile / Modern Client Management Server passwords are susceptible to a brute-force attack","id":"CVE-2021-27782","kev_date_added":null,"published":"2023-01-19"}],"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":"2024-09-16","vendors":["HCL Software"]},"summary":"A stored cross-site scripting vulnerability allows attackers to inject scripts that can steal cookies or session data from users of HCL BigFix Mobile.","url":"https://insights.sbomify.com/CVE-2021-27781/"}
