Title: Alex Linde Alex's Ftp Server Directory Traversal Vulnerability
Severity: HIGH
Description:
Alex's Ftp Server is a freeware FTP server by Alex Linde.
By including relative path references (ie '/.../' sequences) in an FTP GET command, an attacker can obtain read access to directories and files outside the FTP root.
The GET request will traverse to the directory above the current working directory without restriction, and retrieve the specified file. Depending on the files obtained, this can supply an attacker with sensitive system data including directory information, password files or other exploitable data which could be used to further undermine the security of the system.
Affected Products:
- Alex Linde Alex's Ftp Server 0.7.0
