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-2025-43715 in the wild and no public exploit code.\n\nAffected product: Nullsoft Scriptable Install System. 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-2025-43715/ (Markdown: https://insights.sbomify.com/CVE-2025-43715/index.md)","id":"CVE-2025-43715","markdown":"https://insights.sbomify.com/CVE-2025-43715/index.md","name":"CVE-2025-43715","record":{"aliases":["DEBIAN-CVE-2025-43715","GHSA-g9m2-7jc6-pmvf","UBUNTU-CVE-2025-43715"],"analysis":{"component_type":"developer_tool","fix_type":"upgrade","impacts":["privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"NSIS installer","requires_auth":"none","summary":"Local attackers can escalate privileges to SYSTEM by winning a race condition in the temporary plugins directory during NSIS installation.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[],"cvss":{"score":8.1,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:L/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-754","name":"Improper Check for Unusual or Exceptional Conditions"}],"description":"Nullsoft Scriptable Install System (NSIS) before 3.11 on Windows allows local users to escalate privileges to SYSTEM during an installation, because the temporary plugins directory is created under %WINDIR%\\temp and unprivileged users can place a crafted executable file by winning a race condition.
