CVE-2025-1759

5.9 MEDIUM

📋 TL;DR

CVE-2025-1759 is an information disclosure vulnerability in IBM Concert Software where improper heap memory clearing allows remote attackers to read sensitive data from previously allocated memory. This affects IBM Concert Software versions 1.0.0 through 1.1.0. Attackers could potentially access credentials, session tokens, or other sensitive information stored in memory.

💻 Affected Systems

Products:
  • IBM Concert Software
Versions: 1.0.0 through 1.1.0
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

Attackers obtain administrative credentials, session tokens, or sensitive business data from memory, leading to full system compromise or data breach.

🟠

Likely Case

Attackers extract limited sensitive information such as user credentials or session data, potentially enabling further attacks.

🟢

If Mitigated

With proper network segmentation and access controls, impact is limited to information disclosure within isolated segments.

🌐 Internet-Facing: HIGH
🏢 Internal Only: MEDIUM

🎯 Exploit Status

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

Requires network access to the IBM Concert Software service and ability to trigger memory allocation patterns.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 1.1.1 or later

Vendor Advisory: https://www.ibm.com/support/pages/node/7242354

Restart Required: No

Instructions:

1. Download IBM Concert Software version 1.1.1 or later from IBM support portal. 2. Follow IBM's upgrade documentation for your deployment type. 3. Verify successful upgrade using version check command.

🔧 Temporary Workarounds

Network Segmentation

all

Restrict network access to IBM Concert Software to only trusted sources

Memory Sanitization

all

Implement application-level memory clearing for sensitive data

🧯 If You Can't Patch

  • Implement strict network access controls to limit exposure
  • Monitor for unusual memory access patterns and failed authentication attempts

🔍 How to Verify

Check if Vulnerable:

Check IBM Concert Software version via administrative interface or configuration files

Check Version:

Check application configuration or administrative console for version information

Verify Fix Applied:

Confirm version is 1.1.1 or later and test memory allocation patterns

📡 Detection & Monitoring

Log Indicators:

  • Unusual memory allocation patterns
  • Failed authentication attempts followed by memory access
  • Multiple connection attempts from single source

Network Indicators:

  • Repeated requests to trigger memory allocation
  • Traffic patterns suggesting memory probing

SIEM Query:

source="ibm_concert" AND (event_type="memory_allocation" OR auth_failure) | stats count by src_ip
