Title: Rumpus FTP Server Stack Overflow DoS Vulnerability
Severity: MODERATE
Description:
Rumpus FTP Server is an implementation for MacOS which allows file-sharing across TCP/IP connections.
Rumpus FTP is prone to a denial of service. An FTP user can engage the attack by making a directory with an unusual number of sub-folders.
When this happens, stack memory used by the software is overwritten and the FTP is forced to quit operating. Rumpus FTP Server must be rebooted to regain normal functionality.
Additionally, due to the nature of buffer overflow attacks, there may be a possibility that the attacker can execute arbitrary code with the priviledges of the FTP server.
It is required that a user be logged in to carry out this attack. It may be possible for remote users to exploit this vulnerability, but authentication is required and anonymous ftp access does not grant users the privileges neccesary to create directories.
Affected Products:
- Maxum Rumpus FTP Server 1.3.2
- Maxum Rumpus FTP Server 1.3.4
- Maxum Rumpus FTP Server 1.3.5
- Maxum Rumpus FTP Server 2.0.3dev
