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-2021-34579 in the wild and no public exploit code.\n\nAffected product: PHOENIX CONTACT FL MGUARD DM (2981974). 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-2021-34579/ (Markdown: https://insights.sbomify.com/CVE-2021-34579/index.md)","id":"CVE-2021-34579","markdown":"https://insights.sbomify.com/CVE-2021-34579/index.md","name":"CVE-2021-34579","record":{"aliases":["GHSA-987p-cg63-5x62"],"analysis":{"component_type":"network_device","fix_type":"patch","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Industrial firewall","requires_auth":"none","summary":"Attackers can access the Apache web server without credentials to download sensitive configuration profiles containing private keys.","user_interaction":"not_required","vuln_class":"missing_authorization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERTVDE","cpe":[{"product":"fl_mguard_dm","vendor":"phoenixcontact"}],"cvss":{"score":7.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-269","name":"Improper Privilege Management"}],"description":"In Phoenix Contact: FL MGUARD DM version 1.12.0 and 1.13.0 access to the Apache web server being installed as part of the FL MGUARD DM on Microsoft Windows does not require login credentials even if configured during installation.Attackers with network access to the Apache web server can download and therefore read mGuard configuration profiles (“ATV profiles”).
