CVE-1999-1090

Summary

CVE-1999-1090 is a vulnerability affecting the NCSA Telnet package for Macintosh and PC. Contrary to its configuration, this software allows FTP access even when the "ftp=yes" line is missing. This oversight exposes systems to remote attacks, enabling unauthorized users to read and modify arbitrary files. The vulnerability poses a significant risk, as it bypasses the intended access control and could lead to data manipulation or theft. It is recommended that affected systems be updated to a secure version of the Telnet package or that FTP be disabled altogether.
