An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2022-43515 exists.\n\nAffected product: Zabbix Frontend. 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-2022-43515/ (Markdown: https://insights.sbomify.com/CVE-2022-43515/index.md)","id":"CVE-2022-43515","markdown":"https://insights.sbomify.com/CVE-2022-43515/index.md","name":"CVE-2022-43515","record":{"aliases":["DEBIAN-CVE-2022-43515","GHSA-hh7f-cch9-52mr","SUSE-SU-2022:4477-1","UBUNTU-CVE-2022-43515"],"analysis":{"component_type":"web_application","fix_type":"patch","impacts":["security_bypass","data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"Zabbix Frontend","requires_auth":"none","summary":"Attackers can bypass maintenance mode IP restrictions by spoofing the X-Forwarded-For header, gaining unauthorized access to the Zabbix Frontend.","user_interaction":"not_required","vuln_class":"auth_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Zabbix","cpe":[{"product":"frontend","vendor":"zabbix"}],"cvss":{"score":5.3,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N","version":"3.1"},"cwes":[{"id":"CWE-863","name":"Incorrect Authorization"},{"id":"CWE-20","name":"Improper Input Validation"}],"description":"Zabbix Frontend provides a feature that allows admins to maintain the installation and ensure that only certain IP addresses can access it.
