Title: EFTP Buffer Overflow Code Execution and Denial of Service Vulnerability
Severity: CRITICAL
Description:
Encrypted FTP (EFTP) is both an FTP client and server application for Windows platforms.
A malicious user with upload permissions to the target host can cause a buffer overflow by uploading a *.lnk file containing a certain value. When an LS command is issued on this directory, the buffer overflow allows the stack to be overwritten as well as the return address, causing code of the attacker's choosing to be executed on the local host with the same level of permissions as the EFTP process.
Alternatively, the attacker could also use this exploit to cause a denial of service by having the exploit code continually execute a command such as querying the floppy drive of the target host.
Affected Products:
- Cisco iCDN 2.0.0
- Khamil Landross and Zack Jones EFTP 2.0.7 .337
