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-2021-36806 in the wild and no public exploit code.\n\nAffected product: Sophos Email Appliance. 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-2021-36806/ (Markdown: https://insights.sbomify.com/CVE-2021-36806/index.md)","id":"CVE-2021-36806","markdown":"https://insights.sbomify.com/CVE-2021-36806/index.md","name":"CVE-2021-36806","record":{"aliases":["GHSA-f39q-q9f3-6vmw"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Email Appliance","requires_auth":"none","summary":"Reflected XSS in Sophos Email Appliance allows attackers to redirect victims via malicious links on error pages.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Sophos","cpe":[{"product":"email_appliance","vendor":"sophos"}],"cvss":{"score":4.7,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"A reflected XSS vulnerability allows an open redirect when the victim clicks a malicious link to an error page on \n\nSophos Email Appliance \n\nolder than version 4.5.3.4.","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 Sophos Email Appliance","id":"CVE-2021-36806","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":1,"next":{"headline":"SQL injection in SG UTM","id":"CVE-2021-36807"},"packages":[],"prev":{"headline":"Akaunting Invoice Footer Persistent XSS","id":"CVE-2021-36805"},"products":["Sophos Email Appliance"],"published":"2023-11-30","related":[],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-12-02","vendors":["Sophos"]},"summary":"Reflected XSS in Sophos Email Appliance allows attackers to redirect victims via malicious links on error pages.","url":"https://insights.sbomify.com/CVE-2021-36806/"}
