Technical details

Tenable Identity Exposure versions prior to 3.93.5 suffer from missing authentication on several API endpoints located under the /w/api/* path. This vulnerability allows a remote, unauthenticated attacker to query these endpoints and retrieve sensitive configuration data, including cleartext LDAP credentials, SAML configurations, and directory settings. Additionally, the application improperly uses 'Cache-Control: public' headers without a 'Vary: Cookie' header, which can cause downstream reverse proxies or CDNs to cache these sensitive responses and serve them to other unauthenticated users. The issue is categorized under CWE-306 (Missing Authentication for Critical Function) and CWE-524 (Use of Cache Containing Sensitive Information). Users should upgrade to version 3.93.5 or later to remediate these risks.
