CVE-2026-56586: CWE-16: Configuration in HCLSoftware IntelliOps Event Management
HCL IEM was affected with X-Content-Type-Options Header Missing. It may enable attackers to perform SSL stripping or man-in-the-middle attacks and intercept sensitive data.
AI Analysis
Technical Summary
CVE-2026-56586 identifies a configuration weakness in HCLSoftware IntelliOps Event Management version 1.1 where the X-Content-Type-Options HTTP header is missing. This header is important to prevent MIME type sniffing by browsers, and its absence can facilitate SSL stripping or man-in-the-middle attacks that intercept sensitive communications. The CVSS v3.1 base score is 3.1, reflecting low severity due to the attack complexity and limited impact on confidentiality and integrity. No vendor remediation or patch is currently documented.
Potential Impact
The missing X-Content-Type-Options header may enable attackers to downgrade HTTPS connections or intercept data via man-in-the-middle attacks. However, the impact is limited as there is no direct code execution or data corruption. The confidentiality and integrity of data may be partially compromised under specific attack conditions.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, consider implementing compensating controls such as web application firewalls or secure transport enforcement. Monitor vendor communications for updates.
