In Spring Cloud Function versions 3.1.6, 3.2.2 and older unsupported versions, when using routing functionality it is possible for a user to provide a specially crafted SpEL as a routing-expression that may result in remote code execution and access to local resources.

A Spring MVC or Spring WebFlux application running on JDK 9+ may be vulnerable to remote code execution (RCE) via data binding. The specific exploit requires the application to run on Tomcat as a WAR deployment. If the application is deployed as a Spring Boot executable jar, i.e. the default, it is not vulnerable to the exploit. However, the nature of the vulnerability is more general, and there may be other ways to exploit it.

A flaw was found in the Jackson Databind package. This cause of the issue is due to a Java StackOverflow exception and a denial of service via a significant depth of nested objects.

CKEditor is vulnerable to a denial of service, caused by a regular expression denial of service (ReDoS) flaw in the dialog plugin. By sending a specially-crafted regex input, a remote attacker could exploit this vulnerability to cause a significant performance drop and results in a browser tab freeze.

A flaw was found in the Apache Xerces Java (XercesJ) XML parser when handling specially crafted XML document payloads. This issue causes the XercesJ XML parser to wait in an infinite loop, which may consume system resources for a prolonged duration, leading to a denial of service condition.

Apache Kafka could allow a remote attacker to obtain sensitive information, caused by a timing attack flaw due to the use of "Arrays.equals" to validate a password or key. By utilizing brute-force attack techniques, an attacker could exploit this vulnerability to obtain credentials information, and use this information to launch further attacks against the affected system.

CKEditor is vulnerable to cross-site scripting, caused by improper validation of user-supplied input. A remote authenticated attacker could exploit this vulnerability to inject malicious script into a Web page which would be executed in a victim's Web browser within the security context of the hosting Web site, once the page is viewed. An attacker could use this vulnerability to steal the victim's cookie-based authentication credentials.
