Short explanation

GnuPG version 2.5.21 for Windows contains a vulnerability where default DACL inheritance on the C:\ProgramData directory allows the BUILTIN\Users group to create arbitrary subdirectories. A low-privilege attacker can inject malicious configuration files, resulting in code execution within the victim user's security context.

Why does it matter?

This vulnerability allows a low-privilege attacker to manipulate configuration files consumed by GnuPG components, creating the risk of code execution within the victim user's security context.

Show the technical text from the sources

GnuPG (version 2.5.21) for Windows contains a vulnerability where default Discretionary Access Control List (DACL) inheritance on the C:\ProgramData directory allows members of the BUILTIN\Users group to create arbitrary subdirectories under this path. An attacker with low-privilege access can create the expected GnuPG configuration directory and inject malicious configuration files consumed by GnuPG components. This can result in code execution within the security context of the victim user.
