Protect Yourself from Active Template Library Attacks

CVSScvssV3_1: 7.5

The Active Template Library (ATL) is a set of C++ classes used in Microsoft software to simplify the programming of components and servers. Unfortunately, security researchers recently discovered a vulnerability in ATL that could allow remote attackers to cause a denial of service (DoS) condition.

The vulnerability, tracked as CVE-2023-36585, is due to improper validation of user-supplied input in ATL. A malicious actor could craft a specially crafted request that contains overly long or malformed data. When processed by an affected ATL application, this could consume significant system resources or even cause the application to crash.

While ATL is primarily used for Microsoft development, vulnerabilities like this could impact any software that relies on ATL. Web servers, databases, and other internet-facing services are most at risk.

The good news is that developers can mitigate this threat by keeping ALL software up-to-date, including libraries like ATL. Applying the latest patches will prevent exploitation of known issues. It’s also wise for end users to only visit websites using up-to-date browsers and operating systems.

By taking basic security precautions, you can help protect yourself and your data from ATL-based denial of service attacks on Microsoft and other software. Stay vigilant and always keep your apps and systems patched for the best security.
