CVE-2024-28764
📋 TL;DR
CVE-2024-28764 is a CSV injection vulnerability in IBM WebSphere Automation 1.7.0 that allows attackers with network access to execute arbitrary commands on the system. This occurs due to improper validation of CSV file contents. Organizations running IBM WebSphere Automation 1.7.0 are affected.
💻 Affected Systems
- IBM WebSphere Automation
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Full system compromise allowing attacker to execute arbitrary commands with the privileges of the WebSphere Automation process, potentially leading to data theft, system takeover, or lateral movement.
Likely Case
Limited command execution within the application context, potentially allowing file system access, data exfiltration, or further privilege escalation.
If Mitigated
No impact if proper network segmentation and access controls prevent attackers from reaching the vulnerable component.
🎯 Exploit Status
Exploitation requires network access and ability to submit malicious CSV files to the vulnerable component.
