Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-52660 is an Unrestricted File Upload vulnerability affecting HCL AION. This flaw enables the upload of malicious files, which could potentially lead to unauthorized code execution or system compromise. The vulnerability is classified under CWE-644 and has a CVSS v3.1 base score of 2.7 (AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N), indicating low severity primarily due to the high privileges required for exploitation.
Attackers with high-privilege access, such as authenticated administrators, can exploit this vulnerability over the network with low complexity and no user interaction required. Successful exploitation allows limited unauthorized access to confidential information, though the unchanged scope limits broader impacts on integrity or availability. While the description notes potential for code execution or system compromise, the scored impact remains low confidentiality disclosure.

Security testing catches header-injection issues before release, covering most of the weakness.
Secure development lifecycle mandates input validation and output encoding that directly prevents header-injection flaws.
Application security requirements explicitly call for neutralizing untrusted data in HTTP headers.
Secure architecture principles reduce injection surfaces but do not prescribe header-specific controls.
Secure coding standards require proper escaping or rejection of scripting syntax in HTTP headers.
