Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
An elevation of privilege vulnerability exists in the Windows Installer component when MSI packages process symbolic links. The flaw, tracked as CVE-2020-0683 and distinct from CVE-2020-0686, carries a CVSS 3.1 base score of 7.8 and is associated with CWE-59.
A local attacker with low privileges can exploit the issue without user interaction to obtain elevated rights on an affected system, resulting in full control over confidentiality, integrity, and availability of the host.
Microsoft has published security guidance for the vulnerability, and the flaw appears in CISA's catalog of known exploited vulnerabilities, confirming observed in-the-wild exploitation.

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.
Secure SDLC practices directly require code to validate paths and avoid unsafe link following.

Security testing can detect link-following flaws before release.
Secure SDLC practices can mandate link-resolution checks and canonicalization before file access.
Application security requirements can explicitly require safe handling of symbolic links and path traversal.
Secure architecture principles include input validation and safe file-access design patterns.
Secure coding standards directly address canonicalization and symlink attacks during implementation.
Access-control rules can limit which files are reachable, reducing exposure to malicious links.
