CVE-2025-25032

7.5 HIGH

📋 TL;DR

This vulnerability in IBM Cognos Analytics allows authenticated users to send specially crafted requests that exhaust memory resources, causing denial of service. It affects multiple versions of IBM Cognos Analytics 11.2.x and 12.0.x. Only authenticated users can exploit this vulnerability.

💻 Affected Systems

Products:
  • IBM Cognos Analytics
Versions: 11.2.0 through 11.2.4, 12.0.0 through 12.0.4
Operating Systems: All supported platforms
Default Config Vulnerable: ⚠️ Yes
Notes: All deployments of affected versions are vulnerable regardless of configuration.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete service unavailability for all users due to memory exhaustion, requiring system restart and potentially causing data loss or corruption.

🟠

Likely Case

Temporary service degradation or outage affecting multiple users until memory is freed or system is restarted.

🟢

If Mitigated

Minimal impact with proper monitoring and rapid response to memory exhaustion events.

🌐 Internet-Facing: MEDIUM - While authentication is required, internet-facing instances could be targeted by authenticated attackers or compromised accounts.
🏢 Internal Only: HIGH - Internal authenticated users (including legitimate users with malicious intent) can exploit this vulnerability.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires authenticated access but the attack vector appears straightforward based on the CWE-770 description.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: Apply security updates as specified in IBM advisory

Vendor Advisory: https://www.ibm.com/support/pages/node/7234674

Restart Required: Yes

Instructions:

1. Review IBM advisory for specific patch versions. 2. Apply appropriate security updates for your version. 3. Restart Cognos Analytics services. 4. Verify the fix is applied.

🔧 Temporary Workarounds

Rate limiting and request filtering

all

Implement rate limiting and request size limits to prevent memory exhaustion attacks

Memory monitoring and alerting

all

Set up monitoring for memory usage with automatic alerts and auto-restart thresholds

🧯 If You Can't Patch

  • Implement strict access controls and least privilege principles for authenticated users
  • Deploy web application firewall with DoS protection and memory exhaustion detection rules

🔍 How to Verify

Check if Vulnerable:

Check IBM Cognos Analytics version via administration console or configuration files. If version is 11.2.0-11.2.4 or 12.0.0-12.0.4, system is vulnerable.

Check Version:

Check Cognos configuration or administration interface for version information

Verify Fix Applied:

Verify version has been updated to a patched version and test with normal authenticated requests to ensure service stability.

📡 Detection & Monitoring

Log Indicators:

  • Unusually large request sizes
  • Rapid sequence of similar requests from single user
  • Memory exhaustion warnings in system logs
  • Service restart events

Network Indicators:

  • Pattern of large POST requests to Cognos endpoints
  • Requests with abnormal payload sizes

SIEM Query:

source="cognos_logs" AND (message="memory" OR message="out of memory" OR message="restart") AND user!="system"
