High CVSS 8.8

Overview

IBM Cognos Controller 11.0.0 through 11.0.1 FP3 and IBM Controller 11.1.0

is vulnerable to unrestricted deserialization. This vulnerability allows users to execute arbitrary code, escalate privileges, or cause denial of service attacks by exploiting the unrestricted deserialization of types in the application.

Risk analysis

This vulnerability is rated 🟠 HIGH.

  • CVSS: 8.8 (HIGH)
  • Detected tags: deserialization, dos, rce (tag impact: VERY HIGH)

Recommended actions:

  • Avoid untrusted deserialization; prefer safe formats (JSON) and signatures.
  • Rate limiting, resource quotas and circuit breakers.
  • Patch/upgrade immediately (remote code execution).
  • Reduce exposure (WAF/segmentation), minimize attack surface.
