GHSA-26VR-8J45-3R4W

Vulnerability from github – Published: 2021-04-06 17:31 – Updated: 2022-08-10 23:33
VLAI
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 ${jetty.home}/etc/jetty-https.xml and${jetty.home}/etc/jetty-http2.xml to ${jetty.base}/etc
  • Edit files ${jetty.base}/etc/jetty-https.xml and ${jetty.base}/etc/jetty-http2.xml, changing any reference of org.eclipse.jetty.server.SslConnectionFactory to org.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

GHSA-273R-MGR4-V34F

Vulnerability from github – Published: 2022-01-13 16:14 – Updated: 2022-01-21 13:25
VLAI
Summary
Uncaught Exception in engine.io
Details

Impact

A specially crafted HTTP request can trigger an uncaught exception on the Engine.IO server, thus killing the Node.js process.

RangeError: Invalid WebSocket frame: RSV2 and RSV3 must be clear at Receiver.getInfo (/.../node_modules/ws/lib/receiver.js:176:14) at Receiver.startLoop (/.../node_modules/ws/lib/receiver.js:136:22) at Receiver._write (/.../node_modules/ws/lib/receiver.js:83:10) at writeOrBuffer (internal/streams/writable.js:358:12)

This impacts all the users of the engine.io package starting from version 4.0.0, including those who uses depending packages like socket.io.

Patches

A fix has been released for each major branch:

Version range Fixed version
engine.io@4.x.x 4.1.2
engine.io@5.x.x 5.2.1
engine.io@6.x.x 6.1.1

Previous versions (< 4.0.0) are not impacted.

For socket.io users:

Version range engine.io version Needs minor update?
socket.io@4.4.x ~6.1.0 -
socket.io@4.3.x ~6.0.0 Please upgrade to socket.io@4.4.x
socket.io@4.2.x ~5.2.0 -
socket.io@4.1.x ~5.1.1 Please upgrade to socket.io@4.4.x
socket.io@4.0.x ~5.0.0 Please upgrade to socket.io@4.4.x
socket.io@3.1.x ~4.1.0 -
socket.io@3.0.x ~4.0.0 Please upgrade to socket.io@3.1.x or socket.io@4.4.x (see here)

In most cases, running npm audit fix should be sufficient. You can also use npm update engine.io --depth=9999.

Workarounds

There is no known workaround except upgrading to a safe version.

Motorola EBTS/MBTS Site Controller drops to debug prompt on unhandled exception. The Motorola MBTS Site Controller exposes a debug prompt on the device's serial port in case of an unhandled exception. This allows an attacker with physical access that is able to trigger such an exception to extract secret key material and/or gain arbitrary code execution on the device.

Vulnerability from github – Published: 2026-07-28 17:01 – Updated: 2026-07-28 17:01

Summary
SIPSorcery: Malformed UDP packet on the RTP/ICE socket can remotely terminate a media session (DoS)
Details

Impact

A single malformed inbound UDP packet on the RTP/ICE socket can remotely terminate an active RTP or WebRTC media session. The packet receive handler indexes packet (and STUN attribute) bytes without sufficient length checks and throws, and the UDP receive loop converted any such exception into a channel Close rather than dropping the packet. One small, unauthenticated packet therefore ends the media session.

This is reachable during ICE connectivity checks — before the DTLS handshake and before any STUN MESSAGE-INTEGRITY verification. Because the RTP/ICE port is shared/advertised in the ICE candidates, a peer or on-path attacker can reach it (exposure is lower for a blind off-path attacker that must first learn the ephemeral port). Impact is availability only — no loss of confidentiality or integrity.

Affected versions

NuGet package SIPSorcery <= 10.0.8.

Patches

Fixed in 10.0.9.

Root cause

Two issues combine:

  1. Unchecked indexing of untrusted bytes.
  2. RTPChannel.OnRTPPacketReceived read packet[1] after only checking the packet was non-empty, so a 1-byte packet threw IndexOutOfRangeException.

  3. STUNAttribute.ParseMessageAttributes passed a null/short value to the typed attribute parsers, and STUNXORAddressAttribute (and the non-XOR STUNAddressAttribute) then read attributeValue[1], AsSpan(2) and AsSpan(4) with no length check. A STUN message carrying an XOR-MAPPED-ADDRESS, XOR-PEER-ADDRESS or XOR-RELAYED-ADDRESS attribute of length 0–7 threw (NullReferenceException for length 0, IndexOutOfRangeException/ArgumentOutOfRangeException for 1–7).

  4. The UDP receive loop closed the channel on any exception. The catch-all in UdpReceiver.EndReceiveFrom called Close(), tearing down the channel, instead of dropping the offending packet and continuing. This was systemic: any unhandled exception anywhere in the packet pipeline (STUN, RTP, RTCP, DTLS demux, SRTP, TURN) became a channel teardown.

Fix

  • UdpReceiver.EndReceiveFrom: a non-socket exception now logs and drops the single packet and re-arms the receive loop (matching the existing SIPUDPChannel behaviour), instead of closing the channel. Genuine socket failures continue to be handled separately.
  • RTPChannel.OnRTPPacketReceived: requires a minimum packet length (RTPHeader.MIN_HEADER_LEN) before indexing the discriminator bytes.
  • STUN parsing: ParseMessageAttributes validates each attribute value length and skips malformed/truncated attributes; the XOR/address attribute constructors validate length defensively; ParseSTUNMessage no longer dereferences a null attribute list.

Regression tests were added covering the 1-byte packet (channel stays open and remains usable), short/zero-length XOR address attributes (0–7 bytes), and truncated STUN messages.

Workarounds

None within the library short of upgrading. Restricting the RTP/ICE port to known peers at the network layer reduces exposure but does not eliminate it, since a negotiating peer can still trigger the condition.

  "details": "### Impact\n\nA single malformed inbound UDP packet on the RTP/ICE socket can remotely terminate an active RTP or WebRTC media session. The packet receive handler indexes packet (and STUN attribute) bytes without sufficient length checks and throws, and the UDP receive loop converted any such exception into a channel `Close` rather than dropping the packet. One small, unauthenticated packet therefore ends the media session.\n\nThis is reachable during ICE connectivity checks \u2014 before the DTLS handshake and before any STUN `MESSAGE-INTEGRITY` verification. Because the RTP/ICE port is shared/advertised in the ICE candidates, a peer or on-path attacker can reach it (exposure is lower for a blind off-path attacker that must first learn the ephemeral port). Impact is availability only \u2014 no loss of confidentiality or integrity.\n\n### Affected versions\n\nNuGet package `SIPSorcery` `\u003c= 10.0.8`.\n\n### Patches\n\nFixed in `10.0.9`.\n\n### Root cause\n\nTwo issues combine:\n\n1. **Unchecked indexing of untrusted bytes.**\n   - `RTPChannel.OnRTPPacketReceived` read `packet[1]` after only checking the packet was non-empty, so a 1-byte packet threw `IndexOutOfRangeException`.\n   - `STUNAttribute.ParseMessageAttributes` passed a `null`/short value to the typed attribute parsers, and `STUNXORAddressAttribute` (and the non-XOR `STUNAddressAttribute`) then read `attributeValue[1]`, `AsSpan(2)` and `AsSpan(4)` with no length check. A STUN message carrying an `XOR-MAPPED-ADDRESS`, `XOR-PEER-ADDRESS` or `XOR-RELAYED-ADDRESS` attribute of length 0\u20137 threw (`NullReferenceException` for length 0, `IndexOutOfRangeException`/`ArgumentOutOfRangeException` for 1\u20137).\n\n2. **The UDP receive loop closed the channel on any exception.** The catch-all in `UdpReceiver.EndReceiveFrom` called `Close()`, tearing down the channel, instead of dropping the offending packet and continuing. This was systemic: any unhandled exception anywhere in the packet pipeline (STUN, RTP, RTCP, DTLS demux, SRTP, TURN) became a channel teardown.\n\n### Fix\n\n- `UdpReceiver.EndReceiveFrom`: a non-socket exception now logs and drops the single packet and re-arms the receive loop (matching the existing `SIPUDPChannel` behaviour), instead of closing the channel.
