What is CVE-2020-35488?

The NXLog Community Edition has a vulnerability in its fileop module that can be exploited to cause a denial of service (daemon crash) by sending a specially crafted Syslog payload to its Syslog service. This attack necessitates a specific configuration, where the name of the created directory must correlate with a Syslog field. Importantly, directory naming limitations on different operating systems (e.g., restricted directory names like '..' on Linux and 'CON' on Windows) may influence the attack's success.
