Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2023-20891 in the wild and no public exploit code.\n\nAffected product: VMware Isolation segment. 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-2023-20891/ (Markdown: https://insights.sbomify.com/CVE-2023-20891/index.md)","id":"CVE-2023-20891","markdown":"https://insights.sbomify.com/CVE-2023-20891/index.md","name":"CVE-2023-20891","record":{"aliases":["GHSA-m8v3-f26v-mhfj"],"analysis":{"component_type":"cloud_service","fix_type":"patch","impacts":["data_read","privilege_escalation"],"network_reachable":"yes","non_default_config":true,"product_category":"VMware Tanzu Application Service","requires_auth":"low_privilege","summary":"Non-admin users with audit log access can retrieve hex-encoded admin credentials, enabling unauthorized application deployment and privilege escalation.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"vmware","cpe":[{"product":"isolation_segment","vendor":"vmware"},{"product":"tanzu_application_service_for_virtual_machines","vendor":"vmware"}],"cvss":{"score":6.5,"severity":"medium","source":"cna","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-532","name":"Insertion of Sensitive Information into Log File"}],"description":"The VMware Tanzu Application Service for VMs and Isolation Segment contain an information disclosure vulnerability due to the logging of credentials in hex encoding in platform system audit logs. A malicious non-admin user who has access to the platform system audit logs can access hex encoded CF API admin credentials and can push new malicious versions of an application.
