Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
CVE-2025-7620 is a Remote Code Execution vulnerability affecting the cross-browser document creation component produced by Digitware System Integration Corporation. Published on 2025-07-14, the flaw carries a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H) and maps to CWE-494.
Remote attackers can exploit the vulnerability when a user visits a malicious website while the component is active. No privileges are required, but user interaction is necessary. Successful exploitation enables attackers to cause the affected system to download and execute arbitrary programs, leading to high impacts on confidentiality, integrity, and availability.
Advisories from TWCERT provide further details on the vulnerability, available at https://www.twcert.org.tw/en/cp-139-10242-5ab42-2.html and https://www.twcert.org.tw/tw/cp-132-10241-2ec07-1.html.

Mitigating Controls (NIST 800-53 r5) AI
Requires digital signature verification before component installation, directly stopping execution of code downloaded without integrity checks.
Employs integrity verification tools that can identify missing or failed checks on downloaded software after the fact.
Mitigating Controls (NIST CSF 2.0) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.
Directly requires assessing authenticity/integrity of software before acquisition and use, preventing unverified downloads.
Requires cryptographic integrity protections (signatures/hashes) for data-in-transit, covering downloaded code.
Prevents execution of unauthorized software, blocking the outcome of an unchecked download.
Mitigating Controls (ISO/IEC 27001:2022 Annex A) AI
Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→ISO cross-walk (authority under review) — links open the control.
Mandating integrity checks, digital signatures, and origin tracing for ICT components directly reduces the chance that code or firmware lacking an integrity check will be accepted into the organisation’s environment.
