The Windows Pragmatic General Multicast (PGM) vulnerability, identified as CVE-2024-21357, is detailed in the NIST National Vulnerability Database with a high base score of 8.1. This vulnerability, categorized as a remote code execution (RCE) threat, presents a significant risk to Windows systems. According to the Common Vulnerability Scoring System (CVSS) metric, the attack complexity is rated as high (AC:H), indicating that successful exploitation requires advanced preparations by the attacker before launching an attack.
One critical aspect highlighted by the CVSS score is the attack vector, which is identified as network-based (AV:N). This classification implies that the vulnerability can be exploited remotely over a network connection. The Windows PGM protocol, responsible for generating multicast traffic at layer 4, is susceptible to exploitation through specially crafted malicious traffic. Therefore, organizations with Windows systems utilizing PGM should be vigilant and take immediate steps to mitigate this vulnerability.
To exploit this vulnerability, an attacker would need to send carefully crafted malicious traffic to a vulnerable server. This traffic could potentially trigger the execution of unauthorized code on the targeted system, leading to a compromise of system integrity and security. Given the severity of the threat and the potential impact of successful exploitation, organizations are urged to apply necessary patches and implement robust network security measures to prevent unauthorized access and protect their systems from exploitation.
