What is CVE-2021-47893?

AgataSoft PingMaster Pro version 2.1 is vulnerable to a denial of service attack caused by improper handling of input in the Trace Route feature. Attackers can exploit this flaw by entering an excessively long hostname—up to 10,000 characters—into the input field. This action can lead to a crash of the application, potentially causing disruption and instability not only for the affected software but also for the underlying system. Users are advised to refrain from inputting overly long hostnames and to apply any available patches or updates from AgataSoft to mitigate this risk.
