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-2021-43977 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2021-43977/ (Markdown: https://insights.sbomify.com/CVE-2021-43977/index.md)","id":"CVE-2021-43977","markdown":"https://insights.sbomify.com/CVE-2021-43977/index.md","name":"CVE-2021-43977","record":{"aliases":["GHSA-p9j4-9vfh-gj5c"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"SmarterMail email server","requires_auth":"none","summary":"Cross-site scripting vulnerability in SmarterMail allows attackers to inject malicious scripts, potentially leading to session hijacking or code execution.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"smartermail","vendor":"smartertools"}],"cvss":{"score":6.1,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"SmarterTools SmarterMail 16.x through 100.x before 100.0.7803 allows XSS.","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-2021-43977","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2021"},"n_packages":0,"n_references":2,"next":{"headline":"Hardcoded credentials in n/a","id":"CVE-2021-43978"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2021-43976"},"products":["n/a"],"published":"2021-11-17","related":[{"cvss_score":10,"headline":"SmarterTools SmarterMail Unrestricted Upload of File with Dangerous Type","id":"CVE-2025-52691","kev_date_added":"2026-01-26","published":"2025-12-29"},{"cvss_score":9.3,"headline":"SmarterTools SmarterMail Missing Authentication for Critical Function","id":"CVE-2026-24423","kev_date_added":"2026-02-05","published":"2026-01-23"},{"cvss_score":9.3,"headline":"SmarterTools SmarterMail Authentication Bypass Using an Alternate Path or Channel","id":"CVE-2026-23760","kev_date_added":"2026-01-26","published":"2026-01-22"},{"cvss_score":9.8,"headline":"Code injection in n/a","id":"CVE-2021-32234","kev_date_added":null,"published":"2021-11-17"},{"cvss_score":9.8,"headline":"Deserialization in n/a","id":"CVE-2019-7214","kev_date_added":null,"published":"2019-04-24"},{"cvss_score":8.7,"headline":"SmarterTools SmarterMail \u003c Build 9560 Server Local File Inclusion via the /api/v1/report/summary/{type} API","id":"CVE-2026-7807","kev_date_added":null,"published":"2026-05-08"},{"cvss_score":8.2,"headline":"SmarterTools SmarterMail \u003c Build 9610 Cryptographic Weakness via Weak RNG","id":"CVE-2026-40514","kev_date_added":null,"published":"2026-04-27"}],"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":"2024-08-04","vendors":["n/a"]},"summary":"Cross-site scripting vulnerability in SmarterMail allows attackers to inject malicious scripts, potentially leading to session hijacking or code execution.","url":"https://insights.sbomify.com/CVE-2021-43977/"}
