Overview

com.fasterxml.jackson.core:jackson-core is a Core Jackson abstractions, basic JSON streaming API implementation

Affected versions of this package are vulnerable to Denial of Service (DoS) due to missing input size validation when performing numeric type conversions. A remote attacker can exploit this vulnerability by causing the application to deserialize data containing certain numeric types with large values, causing the application to exhaust all available resources.

Details

Denial of Service (DoS) describes a family of attacks, all aimed at making a system inaccessible to its intended and legitimate users.

Unlike other vulnerabilities, DoS attacks usually do not aim at breaching security. Rather, they are focused on making websites and services unavailable to genuine users resulting in downtime.

One popular Denial of Service vulnerability is DDoS (a Distributed Denial of Service), an attack that attempts to clog network pipes to the system by generating a large volume of traffic from many machines.

When it comes to open source libraries, DoS vulnerabilities allow attackers to trigger such a crash or crippling of the service by using a flaw either in the application code or from the use of open source libraries.

Two common types of DoS vulnerabilities:

• High CPU/Memory Consumption- An attacker sending crafted requests that could cause the system to take a disproportionate amount of time to process. For example, commons-fileupload:commons-fileupload.

• Crash - An attacker sending crafted requests that could cause the system to crash. For Example, npm ws package

Remediation

Upgrade com.fasterxml.jackson.core:jackson-core to version 2.15.0-rc1 or higher.

Overview

com.fasterxml.jackson.core:jackson-core is a Core Jackson abstractions, basic JSON streaming API implementation

Affected versions of this package are vulnerable to Stack-based Buffer Overflow due to the parse process, which accepts an unlimited input file with deeply nested data. An attacker can cause a stack overflow and crash the application by providing input files with excessively deep nesting.

Remediation

Overview

io.undertow:undertow-core is a Java web server based on non-blocking IO.

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling (MadeYouReset) through malformed client requests that trigger repeated server-side stream resets without incrementing abuse counters. An attacker can exhaust server resources by sending specially crafted HTTP/2 requests that cause excessive workload through repeated stream aborts.

Overview

io.undertow:undertow-core is a Java web server based on non-blocking IO.

Affected versions of this package are vulnerable to Denial of Service (DoS) through the wildfly-http-client protocol, due to the WriteTimeoutStreamSinkConduit process. This vulnerability can be exploited by repeatedly opening and closing connections immediately, which triggers memory and file descriptor leaks.

Overview

io.undertow:undertow-core is a Java web server based on non-blocking IO.

Affected versions of this package are vulnerable to Uncontrolled Recursion in chunked response handling. An attacker can cause a client to wait indefinitely by sending excessive data without a 0\r\n termination sequence in chunked responses, thereby disrupting service to the server.

Note: This is only exploitable when using NewSessionTicket functionality in TLS 1.3 on Java 17.

Overview

io.undertow:undertow-core is a Java web server based on non-blocking IO.

Affected versions of this package are vulnerable to Uncontrolled Resource Consumption ('Resource Exhaustion') through the handling of URL-encoded request path information on ajp-listener. An attacker can cause the server to process incorrect paths, leading to a disruption of service by sending specially crafted concurrent requests.

Overview

io.undertow:undertow-core is a Java web server based on non-blocking IO.

Affected versions of this package are vulnerable to Uncontrolled Resource Consumption ('Resource Exhaustion') due to insufficient limitations on the amount of CONTINUATION frames that can be sent within a single stream. An attacker can use up compute or memory resources to cause a disruption in service by sending packets to vulnerable servers.

Overview

io.undertow:undertow-core is a Java web server based on non-blocking IO.

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling. An attacker can disrupt service availability by repeatedly sending AJP requests that exceed the configured max-header-size attribute in ajp-listener, leading to the server closing the TCP connection without returning an AJP response.

Note:

This is only exploitable if the max-header-size is set to 64 KB or less.

Overview

io.undertow:undertow-core is a Java web server based on non-blocking IO.

Affected versions of this package are vulnerable to Denial of Service (DoS) via an AJP 400 response, when EAP 7 is improperly sending two response packets, those packets have the reuse flag set even though JBoss EAP closes the connection. A failure occurs when the connection is reused after a 400 by CPING since it reads in the second SEND_HEADERS response packet instead of a CPONG.
