CVE-2025-36093 Overview
IBM Cloud Pak For Business Automation versions 25.0.0, 24.0.1, and 24.0.0 contain an improper access control vulnerability that could allow an attacker to access unauthorized content or perform unauthorized actions through man-in-the-middle (MITM) techniques. This vulnerability stems from client-side enforcement of server-side security (CWE-602), where security controls that should be enforced on the server are instead implemented on the client side, making them susceptible to bypass.
Critical Impact
Attackers positioned in the network path can intercept and manipulate communications to gain unauthorized access to sensitive business automation data and perform actions with elevated privileges, potentially compromising the integrity of automated business processes.

Technical Details for CVE-2025-36093
Vulnerability Analysis
This vulnerability is classified under CWE-602 (Client-Side Enforcement of Server-Side Security), indicating that the application relies on client-side mechanisms to enforce security controls that should be validated on the server. In the context of IBM Cloud Pak for Business Automation, this design flaw allows attackers with network access to intercept communications and bypass intended access restrictions.
The attack requires network positioning to perform man-in-the-middle attacks, meaning the attacker must be able to intercept traffic between the client and the server. While the attack complexity is elevated due to this requirement, successful exploitation can lead to significant confidentiality and integrity impacts without affecting system availability.
Root Cause
The root cause of CVE-2025-36093 lies in improper access control implementation where security decisions are enforced at the client level rather than being properly validated on the server side. This architectural weakness allows attackers who can intercept and modify network traffic to circumvent access controls, as the server does not independently verify that the client's requests comply with the intended security policy.
Attack Vector
The attack vector is network-based, requiring the attacker to position themselves in the communication path between legitimate users and the IBM Cloud Pak for Business Automation server. This can be achieved through various MITM techniques including:
- ARP spoofing on local networks to redirect traffic
- DNS poisoning to redirect requests to attacker-controlled endpoints
- Compromised network infrastructure components
- Rogue wireless access points in enterprise environments
Once positioned, the attacker can intercept requests and responses, modifying them to bypass client-side security controls and access content or perform actions that should be restricted.
Detection Methods for CVE-2025-36093
Indicators of Compromise
- Unusual network traffic patterns between clients and IBM Cloud Pak for Business Automation servers
- Unexpected certificate warnings or TLS negotiation anomalies
- Access logs showing privileged operations from unexpected source IPs or user sessions
- ARP table inconsistencies indicating potential spoofing attempts
Detection Strategies
- Implement network intrusion detection systems (NIDS) to monitor for MITM attack signatures
- Deploy certificate pinning validation monitoring to detect TLS interception attempts
- Enable comprehensive audit logging on IBM Cloud Pak for Business Automation to track access patterns
- Monitor for anomalous authentication patterns or session behavior
Monitoring Recommendations
- Enable detailed access logging for all IBM Cloud Pak for Business Automation components
- Implement real-time alerting for privilege escalation attempts or unauthorized resource access
- Deploy network segmentation monitoring to detect lateral movement attempts
- Utilize SIEM correlation rules to identify potential MITM attack indicators
How to Mitigate CVE-2025-36093
Immediate Actions Required
- Review the IBM Support Article for official guidance and patches
- Audit current access control configurations on affected IBM Cloud Pak for Business Automation instances
- Implement network segmentation to limit exposure of vulnerable systems
- Enable TLS/SSL certificate validation and consider implementing certificate pinning
Patch Information
IBM has released information regarding this vulnerability through their support portal. Organizations running affected versions (24.0.0, 24.0.1, or 25.0.0) should consult the official IBM Security Bulletin for specific patch details and upgrade instructions. Apply the latest security updates and interim fixes as recommended by IBM.
Workarounds
- Implement strict network segmentation to isolate IBM Cloud Pak for Business Automation from untrusted network segments
- Deploy mutual TLS (mTLS) authentication to prevent unauthorized interception
- Use VPN tunnels for administrative access to business automation systems
- Enable enhanced monitoring and logging while awaiting patch deployment
# Network segmentation verification example
# Review firewall rules restricting access to Cloud Pak services
kubectl get networkpolicies -n <cloudpak-namespace>
# Verify TLS configuration on ingress controllers
kubectl describe ingress -n <cloudpak-namespace> | grep -A5 "TLS"
