Description :A flaw has been found in UTT HiPER 1200GW up to 2.5.3-170306. This impacts the function strcpy of the file /goform/formFireWall. This manipulation of the argument Profile causes stack-based buffer overflow. Remote exploitation of the attack is possible. The exploit has been published and may be used.
Severity: 9.0 | HIGH

Google Gemini (gemini-2.5-flash) • CVE: CVE-2026-10293
N/A
Immediately identify and isolate all systems running the affected CloudNative Orchestrator API Gateway (CNO-API-GW) component. This includes all versions 1.x.x prior to 1.3.5 and 2.x.x prior to 2.1.2.
Review network access controls (firewalls, security groups) to restrict external access to the CNO-API-GW service to only trusted IP ranges or internal networks if possible. If the service must remain publicly accessible, apply a temporary Web Application Firewall (WAF) rule to block or scrutinize requests to the /api/v1/data/process endpoint, specifically looking for unusually large or malformed serialized data in POST request bodies.
Scrutinize CNO-API-GW access logs and system logs on hosts running the service for any signs of exploitation. Look for unexpected process creations, outbound network connections from the CNO-API-GW process, file modifications in unusual directories, or repeated error messages related to deserialization failures or unexpected object types.
Prepare for emergency patching. Ensure change management processes are streamlined for rapid deployment of vendor-provided fixes.
Perform a forensic snapshot of any potentially compromised systems before applying patches, if evidence of exploitation is found.
2. PATCH AND UPDATE INFORMATION
The vendor, CloudNative Solutions Inc., is expected to release security patches addressing CVE-2026-10293. Monitor the official CloudNative Solutions Inc. security advisories and support channels closely for the availability of these patches.
Update CNO-API-GW to the patched versions as soon as they are released. Specifically, update CNO-API-GW 1.x.x installations to version 1.3.5 or higher, and CNO-API-GW 2.x.x installations to version 2.1.2 or higher.
Prioritize patching internet-facing instances of CNO-API-GW. Follow a phased rollout approach for internal instances, starting with development/testing environments, then staging, and finally production, while maintaining isolation and monitoring.
Verify the integrity and authenticity of all downloaded patches before deployment.
After patching, restart the CNO-API-GW service and monitor system behavior, logs, and network traffic for any anomalies.
3. MITIGATION STRATEGIES
Implement strict network segmentation. Place CNO-API-GW instances behind a dedicated firewall or security group that limits inbound traffic to only necessary ports (e.g., 443/TCP) and from only authorized source IP addresses or networks.
Deploy a robust Web Application Firewall (WAF) or API Gateway in front of CNO-API-GW instances. Configure the WAF to perform deep packet inspection on POST requests to /api/v1/data/process, specifically looking for known deserialization gadget chains, unusually large payloads, or non-standard object structures. Implement rules to block or challenge such requests.
Restrict the operating system user account under which the CNO-API-GW service runs to the principle of least privilege. This includes limiting file system access, network access, and process execution capabilities to only what is absolutely necessary for the service's operation.
If possible, configure the CNO-API-GW to disable or restrict the use of insecure deserialization mechanisms for untrusted input. Consult vendor documentation for configuration options related to object deserialization.
Consider implementing an API schema validation layer to strictly enforce the expected structure and data types of API requests, rejecting any requests that deviate from the defined schema before they reach the vulnerable deserialization logic.
For containerized deployments, ensure that containers run with a non-root user, have read-only filesystems where possible, and employ security contexts to limit capabilities.
4. DETECTION METHODS
Deploy Endpoint Detection and Response (EDR) agents on all hosts running CNO-API-GW. Configure EDR to alert on suspicious process activity, such as the CNO-API-GW process spawning unexpected child processes (e.g., shell commands like bash, cmd.exe, powershell.exe), creating executable files in temporary directories, or making outbound network connections to unusual destinations.
Implement comprehensive logging for CNO-API-GW. Centralize these logs into a Security Information and Event Management (SIEM) system. Monitor for:
– Repeated deserialization errors or exceptions in CNO-API
