> Looking further into the code focusing on the action and type query strings.
> We can see that the filter variable is getting its value from the
> requestsParameters .
> once the Filter parameter is being populated, an If loop checking whether
> Scope and Type are not Null and next
> the code checks the logRetrievalType is equal to the JOB_LOG_ACTION (which is
> the action query string).
>
> Next the values of logRetrievalScope gets split by , and entering the the if
> loop.
> In the block where ranges of actions are processed ( if (s.contains("-")) \{
> ... } ), an attacker could potentially
> send a specially crafted request with a massive range, such as "1-1000000".
> This would create a for loop
> iterating and adding that many actions to the actionSet , consuming CPU and
> memory resources.
> Though there is a subsequent check against maxNumActionsForLog , this check
> only happens after all the iterations,
> allowing an attacker to consume resources before this check is made -
