Cisco Security Advisory-
The Cisco Content Service Switch (CSS) 11000 series switches do not enforce the correct restrictions for accessing the web management URL.
After successful authentication users are redirected to the web management URL. If users directly connect to the redirected URL they are granted access to the web management interface without having to reauthenticate. This vulnerability results in users gaining access to secure data.
This vulnerability is documented as Cisco bug IDs CSCdu20931 and CSCdw08549.
This advisory will be posted at https://sec.cloudapps.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20010531-arrowpoint-webmgmt.
This advisory is being re-released because the vulnerability was not completely fixed previously. Users are still vulnerable and should apply the workarounds in the Workarounds section to mitigate the affects of the vulnerability.
