Senserva AI Opinion for CVE-2015-7450

IBM WebSphere Application Server deserializes untrusted serialized objects, giving remote attackers arbitrary command execution with a 98 percent EPSS probability and Critical Severity (CVSS 9.8). It belongs to the Java deserialization wave that swept through enterprise middleware. CISA KEV confirms sustained exploitation.

Do this: Patch WebSphere and audit other Java middleware for the same serialized-object exposure.
