Overview

com.fasterxml.jackson.core:jackson-databind is a library which contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor.

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the _findDeserializer() method of TypeDeserializerBase, which caches every unknown type ID as a distinct key in the _deserializers map even when all of them resolve to the same defaultImpl fallback. An attacker can grow that cache without bound for the lifetime of the process, exhausting memory over time, by submitting a stream of novel type identifiers. This requires the application to use name-based polymorphism through @JsonTypeInfo(use = Id.NAME, defaultImpl = ...), to accept attacker-controlled type identifiers, and to reuse the mapper instance across requests.

Remediation

Upgrade com.fasterxml.jackson.core:jackson-databind to version 2.18.11, 2.21.7, 2.22.3 or higher.

Overview

com.fasterxml.jackson.core:jackson-databind is a library which contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor.

Affected versions of this package are vulnerable to Improperly Controlled Modification of Dynamically-Determined Object Attributes in the BeanDeserializerBase.createContextual() method, which applies the per-property exclusions through _handleByNameInclusion() and then rebuilds the property map from the unfiltered original, overwriting the filtered map and restoring every property the exclusion had removed. An attacker can set fields that were marked ignored, enabling mass assignment, by supplying those property names in untrusted JSON during deserialization. Exploitation requires case-insensitive property matching to be enabled via @JsonFormat with ACCEPT_CASE_INSENSITIVE_PROPERTIES alongside per-property @JsonIgnoreProperties.

Remediation

Upgrade com.fasterxml.jackson.core:jackson-databind to version 2.18.9, 2.21.5, 2.22.1 or higher.

Overview

com.fasterxml.jackson.core:jackson-databind is a library which contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor.

Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) in the JDKFromStringDeserializer class, which constructs InetSocketAddress and resolves the hostname through DNS at deserialization time. An attacker can force the server to issue outbound DNS lookups for chosen hostnames by submitting JSON that is deserialized into a type holding an InetSocketAddress field, with no authentication required. The observable effect is limited to DNS resolution of attacker-chosen names, useful for out-of-band interaction or internal resolver probing rather than a full outbound request, and it applies only where the application deserializes untrusted JSON into types containing such fields.

Remediation

Upgrade com.fasterxml.jackson.core:jackson-databind to version 2.18.8, 2.21.4 or higher.

Overview

com.fasterxml.jackson.core:jackson-databind is a library which contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor.

Affected versions of this package are vulnerable to Server-side Request Forgery (SSRF) through the STD_INET_ADDRESS branch in FromStringDeserializer in src/main/java/com/fasterxml/jackson/databind/deser/std/FromStringDeserializer.java. An attacker can trigger outbound DNS lookups and blind SSRF behavior by supplying a hostname string in JSON that is deserialized into java.net.InetAddress. When application code binds untrusted input into an InetAddress field or type, the deserializer calls InetAddress.getByName(value) on the attacker-controlled string and resolves it before any application validation runs. This lets an attacker force DNS-based callbacks or probe internal hostnames, causing unwanted network egress and leaking resolver-visible information.

Overview

com.fasterxml.jackson.core:jackson-databind is a library which contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor.

Affected versions of this package are vulnerable to Use of Externally-Controlled Input to Select Classes or Code ('Unsafe Reflection') through NioPathDeserializer in src/main/java/com/fasterxml/jackson/databind/ext/NioPathDeserializer.java. An attacker can force readValue() to resolve an attacker-controlled java.nio.file.Path URI by supplying a non-file scheme such as jar:, http:, s3:, or a custom provider scheme in untrusted JSON. That input reaches new URI(value) and then Path.of(uri), which falls back to ServiceLoader<FileSystemProvider> resolution and can invoke a matching provider’s getPath(uri) during deserialization. The result is unintended provider loading and provider-driven path handling inside the application, which can trigger denial of service or other side effects depending on what FileSystemProvider implementations are present on the classpath.

Remediation

Upgrade com.fasterxml.jackson.core:jackson-databind to version 2.18.10, 2.21.6, 2.22.2 or higher.

Overview

org.springframework:spring-core is a core package within the spring-framework that contains multiple classes and utilities.

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling via static resource resolution. An attacker can cause denial of service by sending crafted requests that are slow to resolve when accessing file-system-backed static resources, causing HTTP connections to remain occupied and exhausting server resources.

Note: This is only exploitable if all the following are true:

1. The application uses Spring MVC or Spring WebFlux.

2. Static resources are served from the file system.

3. The application is running on Windows.

Remediation

Upgrade org.springframework:spring-core to version 6.2.18, 7.0.7 or higher.

Overview

org.springframework:spring-web is a package that provides a comprehensive programming and configuration model for modern Java-based enterprise applications - on any kind of deployment platform.

Affected versions of this package are vulnerable to Denial of Service (DoS) in the form of improper ETag prefix validation when parsing ETags from the If-Match or If-None-Match request headers. An attacker can exploit this vulnerability to cause denial of service by sending a maliciously crafted conditional HTTP request.

Workaround

Users of older, unsupported versions could enforce a size limit on If-Match and If-None-Match headers, e.g. through a Filter.

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 org.springframework:spring-web to version 5.3.38, 6.0.23, 6.1.12 or higher.

Overview

com.fasterxml.jackson.core:jackson-databind is a library which contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor.

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in the JsonNode.toString() method, which serializes nested node structure recursively without a depth limit. An attacker can crash the application with a StackOverflowError by submitting deeply nested JSON, around 1000 levels in a payload of roughly 2 kB, to a service that parses it with ObjectMapper.readTree() and then serializes the result through JsonNode.toString().

Overview

com.fasterxml.jackson.core:jackson-databind is a library which contains the general-purpose data-binding functionality and tree-model for Jackson Data Processor.

Affected versions of this package are vulnerable to Deserialization of Untrusted Data in the isSafeSubType() method of DefaultBaseTypeLimitingValidator, whose denylist of unsafe base types omits java.lang.Comparable, so the method returns true for any subtype resolved under a Comparable base. An attacker can trigger instantiation of arbitrary classes that implement Comparable, such as java.io.File to reach path-traversal primitives, by sending JSON with attacker-controlled type identifiers. This requires the application to use a bare @JsonTypeInfo with the default validator and no explicit PolymorphicTypeValidator, and a property or class whose declared base type is Comparable.

Workaround

This vulnerability can be avoided by configuring an explicit restrictive PolymorphicTypeValidator, such as a BasicPolymorphicTypeValidator allowlist passed to activateDefaultTyping(), instead of relying on the default validator.

Note: The discoverer of this vulnerability reports that "I have not identified a class implementing Comparable that yields code execution purely through deserialization".

Details

Serialization is a process of converting an object into a sequence of bytes which can be persisted to a disk or database or can be sent through streams. The reverse process of creating object from sequence of bytes is called deserialization. Serialization is commonly used for communication (sharing objects between multiple hosts) and persistence (store the object state in a file or a database). It is an integral part of popular protocols like Remote Method Invocation (RMI), Java Management Extension (JMX), Java Messaging System (JMS), Action Message Format (AMF), Java Server Faces (JSF) ViewState, etc.

Deserialization of untrusted data (CWE-502) is when the application deserializes untrusted data without sufficiently verifying that the resulting data will be valid, thus allowing the attacker to control the state or the flow of the execution.

Overview

org.springframework:spring-web is a package that provides a comprehensive programming and configuration model for modern Java-based enterprise applications - on any kind of deployment platform.

Affected versions of this package are vulnerable to HTTP Response Splitting via the Content-Disposition header when untrusted input is used to construct its value. An attacker can inject malicious characters to break the HTTP header or corrupt the framing of an outbound multipart body by supplying specially crafted file names or values.

Note: This is only exploitable if the application uses non-default or legacy HTTP connectors that do not reject malicious characters in header values, or if untrusted input is used to set the Content-Disposition of a part in an outbound multipart request body.

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 Information Exposure due to the JsonLocation._appendSourceDesc method. An attacker can access up to 500 bytes of unintended memory content by exploiting exception messages that incorrectly read from the beginning of a byte array instead of the logical payload start.

Workaround

This vulnerability can be mitigated by disabling exception message exposure to clients to avoid returning parsing exception messages in HTTP responses and/or disabling source inclusion in exceptions to prevent Jackson from embedding any source content in exception messages, avoiding leakage.

PoC

byte[] buffer = new byte[1000];
System.arraycopy("SECRET".getBytes(), 0, buffer, 0, 6);
System.arraycopy("{ \"bad\": }".getBytes(), 0, buffer, 700, 10);

JsonFactory factory = new JsonFactory();
JsonParser parser = factory.createParser(buffer, 700, 20);
parser.nextToken(); // throws exception

// Exception message will include "SECRET"
