Detection & IOCs extracted from sources · hover to see the quote

• → Detect unauthenticated access to the Tomcat Manager interface on FortiPortal instances, which may indicate exploitation of hard-coded credentials to upload malicious WAR (web application archive) files. ↗
• → Monitor HTTP POST requests to Tomcat Manager deployment endpoints (e.g., /manager/text/deploy or /manager/html/upload) on FortiPortal hosts, especially from unauthenticated or externally sourced connections. ↗
• → Alert on WAR file uploads to FortiPortal's Tomcat Manager from remote/unauthenticated sources, as this is the primary exploitation vector for achieving root command execution. ↗

• · FortiPortal versions 5.2.5 and below, 5.3.5 and below, 6.0.4 and below, and all 5.1.x and 5.0.x versions ship with hard-coded Tomcat Manager credentials, exposing the management interface to unauthenticated remote exploitation. ↗
