Summary
An issue was discovered in the Portrait Dell Color Management application before 3.7.0 for Dell monitors. On Windows, a symbolic link vulnerability allows a local low-privileged user to escalate privileges to Administrator. During installation, the software writes the file CCFLFamily_07Feb11.edr to C:\ProgramData\Portrait Displays\CW\data\i1D3\ while running with elevated privileges. Because the installer does not properly validate symbolic links or reparse points at the destination path, an attacker can create a malicious link that redirects the write operation to an arbitrary system location, enabling arbitrary file creation or overwrite with elevated privileges.
Risk Assessment
The risk is the possibility of privilege escalation by a local user to Administrator level, which can lead to full compromise of the Windows system.
Recommendation
It is recommended to update the Portrait Dell Color Management application to version 3.7.0 or later, which contains a fix for this vulnerability.
