TITLE:
Cisco IOS FTP Server Multiple Vulnerabilities
SECUNIA ADVISORY ID:
SA25199
VERIFY ADVISORY:
http://secunia.com/advisories/25199/
CRITICAL:
Moderately critical
IMPACT:
Security Bypass, DoS, System access
WHERE:
>From remote
OPERATING SYSTEM:
Cisco IOS 12.x
http://secunia.com/product/182/
Cisco IOS 11.x
http://secunia.com/product/183/
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).
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.
As a workaround, it is possible to disable the FTP server by
executing the following command in configuration mode: "no ftp-server
enable". See vendor advisories for more details.
PROVIDED AND/OR DISCOVERED BY:
Reported by the vendor.
