'Description' => %q{
|
||||
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.
