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-2025-34394 in the wild and no public exploit code.\n\nAffected product: Barracuda Networks RMM. 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-2025-34394/ (Markdown: https://insights.sbomify.com/CVE-2025-34394/index.md)","id":"CVE-2025-34394","markdown":"https://insights.sbomify.com/CVE-2025-34394/index.md","name":"CVE-2025-34394","record":{"aliases":["GHSA-57g8-267x-ffc8"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"Barracuda RMM","requires_auth":"none","summary":"Remote attackers can execute arbitrary code via unsafe .NET Remoting deserialization in Barracuda RMM Service Center.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[{"product":"rmm","vendor":"barracuda"}],"cvss":{"score":10,"severity":"critical","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H","version":"4.0"},"cwes":[{"id":"CWE-502","name":"Deserialization of Untrusted Data"}],"description":"Barracuda Service Center, as implemented in the RMM solution, in versions prior to 2025.1.1, exposes a .NET Remoting service that is insufficiently protected against deserialization of arbitrary types.
