Security News > 2023 > July > VMware fixes bug exposing CF API admin credentials in audit logs
VMware has patched an information disclosure vulnerability in VMware Tanzu Application Service for VMs and Isolation Segment caused by credentials being logged and exposed via system audit logs.
Tracked as CVE-2023-20891, the security flaw addressed today by Vmware would allow remote attackers with low privileges to access Cloud Foundry API admin credentials on unpatched systems in low-complexity attacks that don't require user interaction.
This happens because, on unpatched TAS for VMs instances, hex-encoded CF API admin credentials are logged 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," VMware says.
The company still advises all TAS for VMs users affected by CVE-2023-20891 to rotate CF API admin credentials to ensure that attackers can't use any leaked passwords.
VMware provides detailed instructions on changing Cloud Foundry User Account and Authentication admin credentials in this support document.
