> Multiple vulnerabilities in IBM database and middleware products enable remote code execution, denial of service, and data compromise.

CERT-FR has published an advisory covering multiple vulnerabilities discovered across several IBM enterprise products. The affected products include IBM Db2 Big SQL, Sterling Connect:Direct Web Services, WebSphere Hybrid Edition, and WebSphere Service Registry and Repository. These vulnerabilities allow attackers to achieve remote code execution, cause denial of service, bypass security policies, compromise data confidentiality, and perform server-side request forgery (SSRF) attacks. Organizations running these products must apply the appropriate security patches and fixes referenced in IBM's security bulletins to mitigate the identified risks.

## Mentioned in this report

- Vulnerabilities: CVE-2025-62718, CVE-2026-26996, CVE-2026-27903, CVE-2026-27904, CVE-2026-40971, CVE-2026-40974, CVE-2026-8620, CVE-2026-8633, CVE-2026-8644, CVE-2026-9311, CVE-2026-9319, CVE-2026-9330

## Detection guidance (public sample)

### WebSphere Java Server Process Spawning Command Shell

ATT&CK: T1190

WebSphere application server JVM spawning cmd/powershell, a typical post-exploitation sign of RCE against a public-facing IBM WebSphere service. Auto-generated starting point — validate and tune in your environment before deploying. IOC matches can false-positive on shared infrastructure and decay as adversary infrastructure rotates.

```yaml
title: WebSphere Java Server Process Spawning Command Shell
description: Detects the IBM WebSphere JVM spawning a command interpreter (cmd, PowerShell,
  wscript, etc.), which indicates possible exploitation of a remote code execution
  flaw in a public-facing WebSphere product. Generalises on the parent/child relation,
  not on any specific CVE payload.
