Cisco VPN 3000 Concentrator FTP command execution
| cisco-vpn-ftp-command-execution (28539) |  Medium Risk |
Description:
Multiple unspecified vulnerabilities in Cisco VPN 3000 series concentrators could allow a remote attacker to execute certain FTP commands when the concentrator is configured to use FTP as the management protocol, which is disabled by default. A remote attacker could exploit this vulnerability to execute the CWD, MKD, CDUP, SIZE, RNFR and RMD FTP commands, which would allow the attacker to obtain sensitive information or modify the configuration.
