CVE-2022-26659 : Exploit Details and Defense Strategies

A detailed overview of the CVE-2022-26659 vulnerability affecting Docker Desktop installer on Windows versions prior to 4.6.0.

Understanding CVE-2022-26659

This section provides insights into the impact and technical details of the CVE-2022-26659 vulnerability.

What is CVE-2022-26659?

The CVE-2022-26659 vulnerability affects Docker Desktop installer on Windows versions before 4.6.0. It allows an attacker to overwrite any administrator-writable files by creating a symlink in place of where the installer writes its log file. With version 4.6.0 and later, the installer, when run elevated, writes its log files to a location not writable by non-administrator users.

The Impact of CVE-2022-26659

The vulnerability poses a significant security risk as it enables attackers to manipulate installer log files and potentially overwrite critical administrator-writable files, leading to unauthorized access or data corruption.
