AI-suggested

Since the vulnerability involves missing or insecure HTTP headers, mitigation typically involves configuring the web server or application to include the X-Content-Type-Options header with the value 'nosniff'. This prevents browsers from MIME-sniffing responses and mitigates the vulnerability. Organizations using HCL AION should verify and update their HTTP response headers accordingly.

Description

HCL AION has a vulnerability due to the absence or insecurity of the X-Content-Type-Options header. This allows browsers to MIME-sniff responses, which can lead to content being interpreted as an unintended type. Under certain conditions, this behavior may cause unintended effects or security impacts. The vulnerability is classified as CWE-200, indicating exposure of sensitive information to unauthorized actors. The CVSS score is 3.7, reflecting a low severity level.
