CWE-200

 Summary
 
A vulnerability in the web-based interface of Cisco Secure Access
Control System (ACS) could allow an unauthenticated, remote attacker
to view sensitive information on an affected system.
The vulnerability exists because the affected software does not
sufficiently protect system software version information when the
software responds to HTTP requests that are sent to the web-based
interface of the software. An attacker could exploit this
vulnerability by sending crafted HTTP requests to the web-based
interface of the affected software. A successful exploit could allow
the attacker to view sensitive information about the software, which
the attacker could use to conduct additional reconnaissance attacks.
There are no workarounds that address this vulnerability.
