What is CVE-2010-20121?
EasyFTP Server versions up to 1.7.0.11 are susceptible to a stack-based buffer overflow in the FTP command parser, specifically when handling the CWD (Change Working Directory) command. The server insufficiently validates the length of the input string, allowing attackers to overwrite memory on the stack. This leads to the potential for remote code execution without requiring authentication, as the server permits anonymous access by default. The issue was addressed in version 1.7.0.12, which afterwards rebranded the product as UplusFtp.
