Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2017-8040 in the wild and no public exploit code.\n\nAffected product: PCF Single Sign-On for PCF:1.3.x versions prior to 1.3.4, 1.4.x versions prior to 1.4.3. 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-2017-8040/ (Markdown: https://insights.sbomify.com/CVE-2017-8040/index.md)","id":"CVE-2017-8040","markdown":"https://insights.sbomify.com/CVE-2017-8040/index.md","name":"CVE-2017-8040","record":{"aliases":["GHSA-fc7r-qxmj-ff6j"],"analysis":{"component_type":"cloud_service","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"PCF Single Sign-On","requires_auth":"low_privilege","summary":"Privileged users can exploit an XXE vulnerability in the PCF Single Sign-On dashboard to expose data from the service broker file system.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"dell","cpe":[{"product":"single_sign-on_for_pivotal_cloud_foundry","vendor":"vmware"}],"cvss":{"score":6.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-611","name":"Improper Restriction of XML External Entity Reference"}],"description":"In Single Sign-On for Pivotal Cloud Foundry (PCF) 1.3.x versions prior to 1.3.4 and 1.4.x versions prior to 1.4.3, an XXE (XML External Entity) attack was discovered in the Single Sign-On service dashboard.
