CVE-2025-1719

5.9 MEDIUM

📋 TL;DR

IBM Concert versions 1.0.0 through 2.1.0 contain a heap memory disclosure vulnerability where sensitive information from previously allocated memory could be exposed to remote attackers. This occurs due to improper clearing of heap memory before reuse. Organizations running affected IBM Concert versions are vulnerable to information disclosure.

💻 Affected Systems

Products:
  • IBM Concert
Versions: 1.0.0 through 2.1.0
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

Sensitive data such as authentication credentials, session tokens, or proprietary business information could be extracted from memory and used for further attacks.

🟠

Likely Case

Partial memory contents containing application data or configuration information could be leaked, potentially revealing system details or user data.

🟢

If Mitigated

With proper network segmentation and access controls, the impact is limited to information disclosure within the application's memory space.

🌐 Internet-Facing: MEDIUM - Remote attackers can exploit this without authentication, but the information disclosed may vary and requires specific conditions.
🏢 Internal Only: MEDIUM - Internal attackers could extract sensitive information, but the value depends on what data is in memory at exploitation time.

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ⚠️ Yes
Complexity: MEDIUM

Exploitation requires understanding of memory allocation patterns and may yield inconsistent results depending on application state.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 2.1.1 or later

Vendor Advisory: https://www.ibm.com/support/pages/node/7257006

Restart Required: Yes

Instructions:

1. Download IBM Concert version 2.1.1 or later from IBM support. 2. Backup current installation and configuration. 3. Stop IBM Concert services. 4. Apply the update following IBM's installation guide. 5. Restart services and verify functionality.

🔧 Temporary Workarounds

Network Access Restriction

all

Limit network access to IBM Concert to only trusted IP addresses and networks.

Use firewall rules to restrict access to IBM Concert ports (typically 80/443)

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate IBM Concert from untrusted networks
  • Monitor for unusual memory access patterns or information disclosure attempts

🔍 How to Verify

Check if Vulnerable:

Check IBM Concert version via administrative interface or configuration files. Versions 1.0.0 through 2.1.0 are vulnerable.

Check Version:

Check IBM Concert web interface or consult installation documentation for version verification method

Verify Fix Applied:

Verify version is 2.1.1 or later and check that memory clearing functions are properly implemented in updated code.

📡 Detection & Monitoring

Log Indicators:

  • Unusual memory access patterns
  • Multiple failed attempts to access memory addresses
  • Information disclosure in application logs

Network Indicators:

  • Repeated requests to endpoints that trigger memory allocation
  • Unusual traffic patterns to IBM Concert services

SIEM Query:

source="ibm_concert" AND (event_type="memory_access" OR event_type="information_disclosure")
