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-2021-4176 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- livehelperchat (Bitnami): affected all versions; fixed in 3.91.0\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-2021-4176/ (Markdown: https://insights.sbomify.com/CVE-2021-4176/index.md)","id":"CVE-2021-4176","markdown":"https://insights.sbomify.com/CVE-2021-4176/index.md","name":"CVE-2021-4176","record":{"aliases":["BIT-livehelperchat-2021-4176","GHSA-92fp-r453-7wpg"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["code_execution","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Live Helper Chat","requires_auth":"none","summary":"Attackers can inject malicious scripts into Live Helper Chat, potentially stealing user sessions or executing code in victim browsers.","user_interaction":"required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"@huntrdev","cpe":[{"product":"live_helper_chat","vendor":"livehelperchat"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","version":"3.0"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"livehelperchat is vulnerable to Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')","ecosystems":["Bitnami"],"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 (XSS) - Reflected in livehelperchat/livehelperchat","id":"CVE-2021-4176","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Bitnami","product":null,"products":[],"type":"xss","year":"2021"},"n_packages":1,"n_references":2,"next":{"headline":"Generation of Error Message Containing Sensitive Information in livehelperchat/livehelperchat","id":"CVE-2021-4177"},"packages":[{"ecosystem":"Bitnami","fixed":["3.91.0"],"introduced":["0"],"last_affected":[],"package":"livehelperchat","purl":"pkg:bitnami/livehelperchat","source":"BIT-livehelperchat-2021-4176"}],"prev":{"headline":"Cross-site Scripting (XSS) - Stored in livehelperchat/livehelperchat","id":"CVE-2021-4175"},"products":["livehelperchat/livehelperchat"],"published":"2021-12-29","related":[{"cvss_score":9.8,"headline":"livehelperchat Server-Side Template Injection","id":"CVE-2024-27516","kev_date_added":null,"published":"2024-02-28"},{"cvss_score":8.8,"headline":"Host Header injection in password Reset in livehelperchat/livehelperchat","id":"CVE-2022-0935","kev_date_added":null,"published":"2022-04-07"},{"cvss_score":8.8,"headline":"XSS in livehelperchat in livehelperchat/livehelperchat","id":"CVE-2022-1234","kev_date_added":null,"published":"2022-04-06"},{"cvss_score":8.7,"headline":"SSRF on index.php/cobrowse/proxycss/ in livehelperchat/livehelperchat","id":"CVE-2022-1191","kev_date_added":null,"published":"2022-03-31"},{"cvss_score":7.7,"headline":"SSRF filter bypass port 80, 433 in livehelperchat/livehelperchat","id":"CVE-2022-1213","kev_date_added":null,"published":"2022-04-05"},{"cvss_score":7.5,"headline":"Weak secrethash can be brute-forced in livehelperchat/livehelperchat","id":"CVE-2022-1235","kev_date_added":null,"published":"2022-04-05"},{"cvss_score":7.5,"headline":"Loose comparison causes IDOR on multiple endpoints in livehelperchat/livehelperchat","id":"CVE-2022-1176","kev_date_added":null,"published":"2022-03-31"}],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"Bitnami","prefix":"BIT"},{"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":"2024-08-03","vendors":["livehelperchat"]},"summary":"Attackers can inject malicious scripts into Live Helper Chat, potentially stealing user sessions or executing code in victim browsers.","url":"https://insights.sbomify.com/CVE-2021-4176/"}
