An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-11421 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-2018-11421/ (Markdown: https://insights.sbomify.com/CVE-2018-11421/index.md)","id":"CVE-2018-11421","markdown":"https://insights.sbomify.com/CVE-2018-11421/index.md","name":"CVE-2018-11421","record":{"aliases":["GHSA-x8wq-f592-jcqf"],"analysis":{"component_type":"network_device","fix_type":"upgrade","impacts":["data_read","account_takeover"],"network_reachable":"yes","non_default_config":false,"product_category":"Moxa OnCell G3100","requires_auth":"none","summary":"Remote attackers can intercept plain-text proprietary protocol traffic to steal administrator passwords and other sensitive data from Moxa OnCell devices.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"oncell_g3150-hspa-t_firmware","vendor":"moxa"},{"product":"oncell_g3150-hspa_firmware","vendor":"moxa"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-319","name":"Cleartext Transmission of Sensitive Information"}],"description":"Moxa OnCell G3100-HSPA Series version 1.6 Build 17100315 and prior use a proprietary monitoring protocol that does not provide confidentiality, integrity, and authenticity security controls.
