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-2023-0871 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- org.opennms.core:org.opennms.core.xml (Maven): affected from 31.0.8; fixed in 32.0.2\n- org.opennms.core:org.opennms.core.xml (Maven): affected from 31.0.8; fixed in 32.0.2\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-2023-0871/ (Markdown: https://insights.sbomify.com/CVE-2023-0871/index.md)","id":"CVE-2023-0871","markdown":"https://insights.sbomify.com/CVE-2023-0871/index.md","name":"CVE-2023-0871","record":{"aliases":["GHSA-2qc8-r663-v864"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Network monitoring software","requires_auth":"low_privilege","summary":"Attackers can exploit XXE in OpenNMS Horizon to force arbitrary HTTP requests, potentially accessing internal services or sensitive data.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"OpenNMS","cpe":[{"product":"horizon","vendor":"opennms"},{"product":"meridian","vendor":"opennms"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"XXE injection in /rtc/post/ endpoint in OpenMNS Horizon 31.0.8 and versions earlier than 32.0.2 on multiple platforms is vulnerable to XML external entity (XXE) injection, which can be used for instance to force Horizon to make arbitrary HTTP requests to internal and external services. The solution is to upgrade to Meridian 2023.1.6, 2022.1.19, 2021.1.30, 2020.1.38 or Horizon 32.0.2 or newer.
