What is CVE-2019-25588?

The BulletProof FTP Server 2019.0.0.50 is susceptible to a denial of service vulnerability that can be exploited by local attackers. By injecting an excessively long string into the DNS Address field, an attacker can trigger a crash of the application. This vulnerability can be exploited when the attacker enables the DNS Address option in the Firewall settings and invokes the Test function, which processes the input. The malicious input, with a buffer length of 700 bytes or more, can lead to an application crash, disrupting service availability.
