Windows Vulnerabilities Exploit Character Encoding Flaws

🪄 New Windows Vulnerabilities Exploit Character Encoding Flaws. Recent research presented at Black Hat Europe 2024 reveals critical vulnerabilities in Windows stemming from its “Best-Fit” character conversion feature, which can lead to attacks such as Path Traversal, Argument Injection, and Remote Code Execution (RCE). The study highlights how this behavior, particularly in handling non-ASCII characters, can be exploited across various applications, including PHP-CGI and Microsoft Excel. The authors emphasize the challenges of addressing these vulnerabilities within the open-source ecosystem and call for a transition to using Wide Character APIs to mitigate risks. The findings underscore the need for increased awareness and proactive measures to secure systems against these novel attack vectors.
