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-2021-27240 in the wild and no public exploit code.\n\nAffected product: SolarWinds Patch Manager. 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-2021-27240/ (Markdown: https://insights.sbomify.com/CVE-2021-27240/index.md)","id":"CVE-2021-27240","markdown":"https://insights.sbomify.com/CVE-2021-27240/index.md","name":"CVE-2021-27240","record":{"aliases":["GHSA-hxhw-4jhr-hg8m"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"SolarWinds Patch Manager","requires_auth":"low_privilege","summary":"Local attackers can escalate privileges to Administrator via unsafe deserialization in the DataGridService WCF service.","user_interaction":"not_required","vuln_class":"deserialization"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"zdi","cpe":[{"product":"patch_manager","vendor":"solarwinds"}],"cvss":{"score":7.8,"severity":"high","source":"cna","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-502","name":"Deserialization of Untrusted Data"}],"description":"This vulnerability allows local attackers to escalate privileges on affected installations of SolarWinds Patch Manager 2020.2.1. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the DataGridService WCF service. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of Administrator.
