Description:
Some vulnerabilities have been reported in Cisco IOS, which can be exploited by malicious users and malicious people to bypass certain security restrictions, cause a DoS (Denial of Service), or potentially compromise a vulnerable system.
1) An unspecified error exists in the IOS FTP server when verifying user credentials, which can be exploited to bypass user authentication.
2) An unspecified error exists when transferring files via FTP, which can be exploited to cause a DoS (Denial of Service) and potentially allow execution of arbitrary code.
Successful exploitation may allow an attacker to retrieve any file from an affected system (including startup-config), cause IOS to reload, and potentially execute arbitrary code, but requires that the FTP server is enabled, which is not the default setting.
The vulnerabilities are reported in IOS version 11.3, 12.0, 12.1, 12.2, 12.3, and 12.4 containing the FTP server feature.
Solution:
The vendor has issued an update that removes the FTP server ability. See vendor advisories for more details.
Provided and/or discovered by:
