Spring Cloud Gateway Actuator Endpoint Remote Code Execution
Actively exploited in the wild. Patch or mitigate immediately — don't wait for a maintenance window.
An unauthenticated attacker, remotely over the network, with no user interaction, can fully compromise the system — steal data, tamper with it and take it offline.
In spring cloud gateway versions prior to 3.1.1+ and 3.0.7+ , applications are vulnerable to a code injection attack when the Gateway Actuator endpoint is enabled, exposed and unsecured. A remote attacker could make a maliciously crafted request that could allow arbitrary remote execution on the remote host.
Techniques marked “observed” are corroborated by threat intelligence; the rest are inferred from the weakness type (CWE) and attack vector.

Generated by Wavense from the CVE record — an immediate mitigation and the permanent fix.
Immediately disable or restrict access to the Gateway Actuator endpoint if it is currently enabled and exposed. Implement strong network access controls, such as firewall rules, to block external or untrusted network access to these endpoints, and ensure robust authentication and authorization are in place for any necessary internal exposure.
Upgrade Spring Cloud Gateway to a patched version as soon as possible. Affected applications should upgrade to version 3.1.1 or later, or to version 3.0.7 or later. These updated versions contain the necessary fixes to prevent the code injection vulnerability.
A remote attacker can achieve arbitrary code execution on the affected server by sending a maliciously crafted request to an exposed and unsecured Gateway Actuator endpoint. This critical vulnerability allows for full system compromise, leading to data breaches, service disruption, and complete unauthorized control over the host.

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.
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.
XStream is a simple library to serialize objects to XML and back again. In affected versions this vulnerability may allow a remote attacker has sufficient rights to execute commands of the host only by manipulating the processed input stream. No user is affected, who followed the recommendation to setup XStream's security framework with a whitelist limited to the minimal required types. XStream 1.4.18 uses no longer a blacklist by default, since it cannot be secured for general purpose.

The deprecated compatibility function clnt_create in the sunrpc module of the GNU C Library (aka glibc) through 2.34 copies its hostname argument on the stack without validating its length, which may result in a buffer overflow, potentially resulting in a denial of service or (if an application is not built with a stack protector enabled) arbitrary code execution.
