CVE-2024-28767
📋 TL;DR
This vulnerability allows remote authenticated attackers to execute arbitrary commands on IBM Security Directory Integrator systems by sending specially crafted requests. It affects IBM Security Directory Integrator versions 7.2.0 through 7.2.0.13 and 10.0.0 through 10.0.3. Attackers need valid credentials to exploit this command injection flaw.
💻 Affected Systems
- IBM Security Directory Integrator
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining complete control over the server, allowing data theft, lateral movement, and persistent backdoor installation.
Likely Case
Unauthorized command execution leading to data exfiltration, privilege escalation, or service disruption.
If Mitigated
Limited impact with proper network segmentation, least privilege access, and command execution restrictions in place.
🎯 Exploit Status
Exploitation requires authenticated access but command injection vulnerabilities are typically straightforward to weaponize once details are known.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 7.2.0.14 and 10.0.4
Vendor Advisory: https://www.ibm.com/support/pages/node/7179558
Restart Required: Yes
Instructions:
1. Download patches from IBM Fix Central. 2. Apply patch for your version (7.2.0.14 for 7.2.x, 10.0.4 for 10.0.x). 3. Restart IBM Security Directory Integrator services. 4. Verify successful update.
🔧 Temporary Workarounds
Network Access Restriction
allRestrict network access to IBM Security Directory Integrator to only trusted IP addresses and required users.
Least Privilege Authentication
allImplement strict authentication controls and limit user permissions to minimum required functionality.
🧯 If You Can't Patch
- Implement strict network segmentation and firewall rules to limit access to the vulnerable system
- Apply principle of least privilege to all user accounts and monitor for suspicious authentication attempts
