Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-40143 in the wild and no public exploit code.\n\nAffected product: Westermo Lynx. 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-2023-40143/ (Markdown: https://insights.sbomify.com/CVE-2023-40143/index.md)","id":"CVE-2023-40143","markdown":"https://insights.sbomify.com/CVE-2023-40143/index.md","name":"CVE-2023-40143","record":{"aliases":["GHSA-7xgh-8hg2-6j33"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["code_execution","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Westermo Lynx","requires_auth":"low_privilege","summary":"An attacker can inject arbitrary JavaScript into the Westermo Lynx web application via the forward.0.domain parameter, potentially compromising user sessions.","user_interaction":"not_required","vuln_class":"xss"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"l206-f2g_firmware","vendor":"westermo"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-79","name":"Improper Neutralization of Input During Web Page Generation"}],"description":"An attacker with access to the Westermo Lynx web application that has the vulnerable software could introduce arbitrary JavaScript by injecting a cross-site scripting payload into the \"forward.0.domain\" parameter.","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":"Westermo Lynx","id":"CVE-2023-40143","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"xss","year":"2023"},"n_packages":0,"n_references":1,"next":{"headline":"Command injection in DR-16F, DR-8F, DR-4F, DR-16H, DR-8H, DR-4H, DR-4M41 series","id":"CVE-2023-40144"},"packages":[],"prev":{"headline":"Privilege escalation in Android","id":"CVE-2023-40142"},"products":["Lynx"],"published":"2024-02-06","related":[{"cvss_score":8,"headline":"Westermo Lynx 206-F2G Cross-Site Request Forgery","id":"CVE-2023-38579","kev_date_added":null,"published":"2024-02-06"},{"cvss_score":8,"headline":"Westermo Lynx Code Injection","id":"CVE-2023-45735","kev_date_added":null,"published":"2024-02-06"},{"cvss_score":6.6,"headline":"Westermo Lynx Permissive Cross-domain Policy with Untrusted Domains","id":"CVE-2023-45213","kev_date_added":null,"published":"2024-02-06"},{"cvss_score":5.7,"headline":"Westermo Lynx Cleartext Transmission of Sensitive Information","id":"CVE-2023-40544","kev_date_added":null,"published":"2024-02-06"},{"cvss_score":5.4,"headline":"Westermo Lynx Cross-site Scripting","id":"CVE-2023-42765","kev_date_added":null,"published":"2024-02-06"},{"cvss_score":5.4,"headline":"Westermo Lynx Cross-site Scripting","id":"CVE-2023-45222","kev_date_added":null,"published":"2024-02-06"}],"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":"2024-08-02","vendors":["Westermo"]},"summary":"An attacker can inject arbitrary JavaScript into the Westermo Lynx web application via the forward.0.domain parameter, potentially compromising user sessions.","url":"https://insights.sbomify.com/CVE-2023-40143/"}
