Denial of Service Vulnerability in Cisco Content Service Switch (CSS) 11000 and 11500 DNS Server

CVE-2003-1132 · MEDIUM Severity

AV:N/AC:L/AU:N/C:N/I:N/A:P

The DNS server for Cisco Content Service Switch (CSS) 11000 and 11500, when prompted for a nonexistent AAAA record, responds with response code 3 (NXDOMAIN or "Name Error") instead of response code 0 ("No Error"), which allows remote attackers to cause a denial of service (inaccessible domain) by forcing other DNS servers to send and cache a request for a AAAA record to the vulnerable server.
