It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-5441 in the wild and no public exploit code.\n\nAffected product: PHOENIX CONTACT mGuard. 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-2018-5441/ (Markdown: https://insights.sbomify.com/CVE-2018-5441/index.md)","id":"CVE-2018-5441","markdown":"https://insights.sbomify.com/CVE-2018-5441/index.md","name":"CVE-2018-5441","record":{"aliases":["GHSA-xgqm-f6fc-576h"],"analysis":{"component_type":"ics_ot","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"ICS security appliance","requires_auth":"low_privilege","summary":"Attackers can modify firmware update packages due to improper integrity checks, potentially leading to unauthorized code execution on PHOENIX CONTACT mGuard devices.","user_interaction":"not_required","vuln_class":"other"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"icscert","cpe":[{"product":"mguard_centerport_firmware","vendor":"phoenixcontact"},{"product":"mguard_core_tx_vpn_firmware","vendor":"phoenixcontact"},{"product":"mguard_delta_tx\\/tx_firmware","vendor":"phoenixcontact"},{"product":"mguard_delta_tx\\/tx_vpn_firmware","vendor":"phoenixcontact"},{"product":"mguard_gt\\/gt_firmware","vendor":"phoenixcontact"},{"product":"mguard_gt\\/gt_vpn_firmware","vendor":"phoenixcontact"},{"product":"mguard_pci4000_vpn_firmware","vendor":"phoenixcontact"},{"product":"mguard_pcie4000_vpn_firmware","vendor":"phoenixcontact"},{"product":"mguard_rs2000_3g_vpn_firmware","vendor":"phoenixcontact"},{"product":"mguard_rs2000_4g_vpn_firmware","vendor":"phoenixcontact"},{"product":"mguard_rs2000_tx\\/tx-b_firmware","vendor":"phoenixcontact"},{"product":"mguard_rs2000_tx\\/tx_vpn_firmware","vendor":"phoenixcontact"},{"product":"mguard_rs2005_tx_vpn_firmware","vendor":"phoenixcontact"},{"product":"mguard_rs4000_3g_vpn_firmware","vendor":"phoenixcontact"},{"product":"mguard_rs4000_4g_vpn_firmware","vendor":"phoenixcontact"},{"product":"mguard_rs4000_tx\\/tx-p_firmware","vendor":"phoenixcontact"},{"product":"mguard_rs4000_tx\\/tx_firmware","vendor":"phoenixcontact"},{"product":"mguard_rs4000_tx\\/tx_vpn-m_firmware","vendor":"phoenixcontact"},{"product":"mguard_rs4000_tx\\/tx_vpn_firmware","vendor":"phoenixcontact"},{"product":"mguard_rs4004_tx\\/dtx_firmware","vendor":"phoenixcontact"},{"product":"mguard_rs4004_tx\\/dtx_vpn_firmware","vendor":"phoenixcontact"},{"product":"mguard_smart2_firmware","vendor":"phoenixcontact"},{"product":"mguard_smart2_vpn_firmware","vendor":"phoenixcontact"}],"cvss":{"score":7.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-20","name":"Improper Input Validation"},{"id":"CWE-354","name":"Improper Validation of Integrity Check Value"}],"description":"An Improper Validation of Integrity Check Value issue was discovered in PHOENIX CONTACT mGuard firmware versions 7.2 to 8.6.0. mGuard devices rely on internal checksums for verification of the internal integrity of the update packages.
