Hackers exploiting buffer overflow vulnerabilities in CVEs are targeted in warnings issued by the FBI and CISA, signaling potential for cyberattacks
In a recent warning issued by the FBI and the Cybersecurity and Infrastructure Security Agency (CISA), several critical buffer overflow vulnerabilities have been highlighted as potential threats for malicious attacks. These vulnerabilities, found in various software products, underscore the importance of secure software development practices.
The Ivanti Connect Secure and Ivanti Policy Secure vulnerability, tracked as CVE-2025-0282, is a stack-based buffer overflow vulnerability. This type of vulnerability can lead to data corruption, program crashes, exposure of sensitive data, and even remote code execution.
Similarly, the Citrix Netscaler ADC and Netscaler Gateway, tracked as CVE-2023-6549, and the VMware vCenter Server, tracked as CVE-2024-38812, have also been identified with buffer overflow vulnerabilities. These vulnerabilities can pose significant risks to the security and integrity of the affected systems.
Buffer overflow vulnerabilities occur when a hacker gains access or writes information outside of the memory buffer. This is often due to the lack of bounds checking and robust memory management, which are crucial aspects in preventing such issues.
Memory-safe programming languages play a crucial role in preventing buffer overflow vulnerabilities. These languages enforce bounds checking, implement robust memory management, encourage safe coding practices, and ensure secure interoperability with other languages. Examples of memory-safe languages include Rust, Go, and Java. In contrast, languages like C and C++, which require manual memory management, are more vulnerable to memory-related issues.
Secure by design is an effort to eliminate vulnerabilities during the software development phase. This approach aims to shift the burden of product security towards manufacturers, protecting organizations from malicious attacks using buffer overflow vulnerabilities.
Chris Wysopal, founder and chief security evangelist at Veracode, emphasized the importance of secure software development, stating, "It's crucial that developers prioritize security from the outset, using memory-safe languages and following secure coding practices to prevent vulnerabilities like buffer overflows."
The warning from the FBI and CISA is part of CISA's push to encourage the use of memory-safe languages in software development. By adopting these practices, developers can significantly reduce the risk of buffer overflow vulnerabilities and improve the overall security of their software products.

In the wake of the recent cybersecurity warning from the FBI and CISA, the vulnerabilities in Ivanti Connect Secure, Ivanti Policy Secure (CVE-2025-0282), Citrix Netscaler ADC and Netscaler Gateway (CVE-2023-6549), and VMware vCenter Server (CVE-2024-38812) highlight the critical need for memory-safe programming languages in data-and-cloud-computing environments. These languages, which include Rust, Go, and Java, enforce bounds checking, implement robust memory management, and encourage safe coding practices, thereby preventing buffer overflow vulnerabilities that can lead to data corruption, program crashes, exposure of sensitive data, and even remote code execution.
