Stack-based Buffer Overflows in ProFTPD Allow Remote Code Execution

CVE-2010-4221

What is CVE-2010-4221?

ProFTPD, a popular FTP server software, is susceptible to multiple stack-based buffer overflow vulnerabilities due to improper handling of the TELNET IAC escape character in the 'pr_netio_telnet_gets' function. These vulnerabilities allow remote attackers to exploit the flaws, potentially leading to arbitrary code execution on affected FTP and FTPS servers. Users are advised to upgrade to version 1.3.3c or later to mitigate this risk.

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
