What is CVE-2019-25637?

X-NetStat Pro 5.63 is susceptible to a local buffer overflow vulnerability that enables local attackers to execute arbitrary code. By manipulating a 264-byte buffer, an attacker could overwrite the EIP register, allowing them to inject and execute shellcode within the application. This vulnerability is particularly exploitable when malicious input is processed through the application's HTTP Client or Rules functionality, using an egg hunter technique to successfully locate and execute the injected payload.
