Description

In Spring Framework versions 6.0.15 and 6.1.2, it is possible for a user to provide specially crafted HTTP requests that may cause a denial-of-service (DoS) condition.

Specifically, an application is vulnerable when all of the following are true:

• the application uses Spring MVC
• Spring Security 6.1.6+ or 6.2.1+ is on the classpath
…

Specifically, an application is vulnerable when all of the following are true:

• the application uses Spring MVC or Spring WebFlux
• io.micrometer:micrometer-core is on the classpath
• an ObservationRegistry is configured in the application to record observations

Description

In Reactor Netty HTTP Server, versions 1.1.x prior to 1.1.13 and versions 1.0.x prior to 1.0.39, a malicious user can send a request using a specially crafted URL that can lead to a directory traversal attack.

Specifically, an application is…

Description

In 2016, allowed list patterns for deserializable class names were added to Spring AMQP, allowing users to lock down deserialization of data in messages from untrusted sources; however by default, when no allowed list was provided, all classes…

Description

A batch loader function in Spring for GraphQL versions 1.1.0 - 1.1.5 and 1.2.0 - 1.2.2 may be exposed to GraphQL context with values, including security context values, from a different session. An application is vulnerable if it provides a DataLoaderOptions instance when registering batch loader…

Description

The spring-security.xsd file inside the spring-security-config jar is world writable which means that if it were extracted it could be written by anyone with access to the file system.

While there are no known exploits, this is an example of “CWE…

Description

In Spring for Apache Kafka 3.0.9 and earlier and versions 2.9.10 and earlier, a possible deserialization attack vector existed, but only if unusual configuration was applied. An attacker would have to construct a malicious serialized object in one of the deserialization exception record headers.

Specifically, an application is vulnerable when all of the following are true:

• The user does not configure an ErrorHandlingDeserializer for the key and/or value of the record
• The user explicitly sets container properties checkDeserExWhenKeyNull and/or checkDeserExWhenValueNull container properties to true.
• The user allows untrusted sources to publish to a Kafka topic

By default, these properties are false, and the container only attempts to deserialize the headers if an ErrorHandlingDeserializer is configured. The ErrorHandlingDeserializer prevents the vulnerability by removing any such malicious headers…

Description

Using "**" as a pattern in Spring Security configuration for WebFlux creates a mismatch in pattern matching between Spring Security and Spring WebFlux, and the potential for a security bypass.
