Details
An issue was discovered in iPortalis iCS 7.1.13.0. Attackers can send a sequence of requests to rapidly cause .NET Input Validation errors. This increases the size of the log file on the remote server until memory is exhausted, therefore consuming the maximum amount of resources (triggering a denial of service condition).

Summary
Jetty vulnerable to incorrect handling of invalid large TLS frame, exhausting CPU resources
Details
Impact
When using SSL/TLS with Jetty, either with HTTP/1.1, HTTP/2, or WebSocket, the server may receive an invalid large (greater than 17408) TLS frame that is incorrectly handled, causing CPU resources to eventually reach 100% usage.
Workarounds
The problem can be worked around by compiling the following class:
package org.eclipse.jetty.server.ssl.fix6072;
import java.nio.ByteBuffer;
import javax.net.ssl.SSLEngine;
import javax.net.ssl.SSLEngineResult;
import javax.net.ssl.SSLException;
import javax.net.ssl.SSLHandshakeException;
import org.eclipse.jetty.io.EndPoint;
import org.eclipse.jetty.io.ssl.SslConnection;
import org.eclipse.jetty.server.Connector;
import org.eclipse.jetty.server.SslConnectionFactory;
import org.eclipse.jetty.util.BufferUtil;
import org.eclipse.jetty.util.annotation.Name;
import org.eclipse.jetty.util.ssl.SslContextFactory;
public class SpaceCheckingSslConnectionFactory extends SslConnectionFactory
{
public SpaceCheckingSslConnectionFactory(@Name("sslContextFactory") SslContextFactory factory, @Name("next") String nextProtocol)
{
super(factory, nextProtocol);
}
@Override
protected SslConnection newSslConnection(Connector connector, EndPoint endPoint, SSLEngine engine)
{
return new SslConnection(connector.getByteBufferPool(), connector.getExecutor(), endPoint, engine, isDirectBuffersForEncryption(), isDirectBuffersForDecryption())
{
@Override
protected SSLEngineResult unwrap(SSLEngine sslEngine, ByteBuffer input, ByteBuffer output) throws SSLException
{
SSLEngineResult results = super.unwrap(sslEngine, input, output);
if ((results.getStatus() == SSLEngineResult.Status.BUFFER_UNDERFLOW ||
results.getStatus() == SSLEngineResult.Status.OK && results.bytesConsumed() == 0 && results.bytesProduced() == 0) &&
BufferUtil.space(input) == 0)
{
BufferUtil.clear(input);
throw new SSLHandshakeException("Encrypted buffer max length exceeded");
}
return results;
}
};
}
}
This class can be deployed by:
+ The resulting class file should be put into a jar file (eg sslfix6072.jar)
+ The jar file should be made available to the server. For a normal distribution this can be done by putting the file into ${jetty.base}/lib
+ Copy the file ${jetty.home}/modules/ssl.mod to ${jetty.base}/modules
+ Edit the ${jetty.base}/modules/ssl.mod file to have the following section:
[lib]
lib/sslfix6072.jar
- Copy the file
${jetty.home}/etc/jetty-https.xmland${jetty.home}/etc/jetty-http2.xmlto${jetty.base}/etc - Edit files
${jetty.base}/etc/jetty-https.xmland${jetty.base}/etc/jetty-http2.xml, changing any reference oforg.eclipse.jetty.server.SslConnectionFactorytoorg.eclipse.jetty.server.ssl.fix6072.SpaceCheckingSslConnectionFactory. For example:
<Call name="addIfAbsentConnectionFactory">
<Arg>
<New class="org.eclipse.jetty.server.ssl.fix6072.SpaceCheckingSslConnectionFactory">
<Arg name="next">http/1.1</Arg>
<Arg name="sslContextFactory"><Ref refid="sslContextFactory"/></Arg>
</New>
</Arg>
</Call>
- Restart Jetty

Mitigation
Architecture and Design
Design throttling mechanisms into the system architecture. The best protection is to limit the amount of resources that an unauthorized user can cause to be expended. A strong authentication and access control model will help prevent such attacks from occurring in the first place. The login application should be protected against DoS attacks as much as possible. Limiting the database access, perhaps by caching result sets, can help minimize the resources expended. To further limit the potential for a DoS attack, consider tracking the rate of requests received from users and blocking requests that exceed a defined rate threshold.
Mitigation
Architecture and Design
- Mitigation of resource exhaustion attacks requires that the target system either:
- The first of these solutions is an issue in itself though, since it may allow attackers to prevent the use of the system by a particular valid user. If the attacker impersonates the valid user, they may be able to prevent the user from accessing the server in question.
- The second solution is simply difficult to effectively institute -- and even when properly done, it does not provide a full solution. It simply makes the attack require more resources on the part of the attacker.
- recognizes the attack and denies that user further access for a given amount of time, or
- uniformly throttles all requests in order to make it more difficult to consume resources more quickly than they can again be freed.
Mitigation
Architecture and Design
Ensure that protocols have specific limits of scale placed on them.
Mitigation
Implementation
Ensure that all failures in resource allocation place the system into a safe posture.
CAPEC-147: XML Ping of the Death
An attacker initiates a resource depletion attack where a large number of small XML messages are delivered at a sufficiently rapid rate to cause a denial of service or crash of the target. Transactions such as repetitive SOAP transactions can deplete resources faster than a simple flooding attack because of the additional resources used by the SOAP protocol and the resources necessary to process SOAP messages. The transactions used are immaterial as long as they cause resource utilization on the target. In other words, this is a normal flooding attack augmented by using messages that will require extra processing on the target.
CAPEC-227: Sustained Client Engagement
An adversary attempts to deny legitimate users access to a resource by continually engaging a specific resource in an attempt to keep the resource tied up as long as possible. The adversary's primary goal is not to crash or flood the target, which would alert defenders; rather it is to repeatedly perform actions or abuse algorithmic flaws such that a given resource is tied up and not available to a legitimate user. By carefully crafting a requests that keep the resource engaged through what is seemingly benign requests, legitimate users are limited or completely denied access to the resource.
CAPEC-492: Regular Expression Exponential Blowup
An adversary may execute an attack on a program that uses a poor Regular Expression(Regex) implementation by choosing input that results in an extreme situation for the Regex. A typical extreme situation operates at exponential time compared to the input size. This is due to most implementations using a Nondeterministic Finite Automaton(NFA) state machine to be built by the Regex algorithm since NFA allows backtracking and thus more complex regular expressions.
