'Name' => 'F5 BigIP Access Policy Manager Session Exhaustion Denial of Service',
'Description' => %q{
An unauthenticated attacker can establish multiple connections with BigIP Access Policy Manager
and exhaust all available sessions defined in customer\'s license.
In the first step of BigIP APM protocol the client sends a HTTP request.
The BigIP system creates a session, marks it as progress (pending) and then redirects client to access policy URI.
Since BigIP allocates a new session after the first unauthenticated request and deletes the session only if an access policy timeout will be expired
the attacker can exhaust all available sessions repeatedly sending initial HTTP request.
This module exploits a resource exhaustion denial of service in F5 BigIP devices. An
unauthenticated attacker can establish multiple connections with BigIP Access Policy
Manager (APM) and exhaust all available sessions defined in customer license. In the
first step of the BigIP APM negotiation the client sends a HTTP request. The BigIP
system creates a session, marks it as pending and then redirects the client to an access
policy URI. Since BigIP allocates a new session after the first unauthenticated request,
and deletes the session only if an access policy timeout expires, the attacker can exhaust
all available sessions by repeatedly sending the initial HTTP request and leaving the
sessions as pending.
