Recently, two vulnerabilities were announced within the Spring Framework, an open-source framework for building enterprise Java applications. On March 29, 2022, the Spring Cloud Expression Resource Access Vulnerability tracked in CVE-2022-22963 was patched with the release of Spring Cloud Function 3.1.7 and 3.2.3. Two days later on March 31, 2022, Spring released version 5.3.18 and 5.2.20 of Spring Framework to patch another more severe vulnerability tracked in CVE-2022-22965. The CVE-2022-22965 vulnerability allows an attacker unauthenticated remote code execution (RCE), which Unit 42 has observed being exploited in the wild. The exploitation of this vulnerability could result in a webshell being installed onto the compromised server that allows further command execution.

Because the Spring Framework is widely used for web system development and the severity of the vulnerability is critical (CVSS score of 9.8), CVE-2022-22965 is given the name SpringShell (and/or Spring4Shell) by the infosec community. To understand the impact of this vulnerability, we analyzed all the available information and located the issue in the source code.

Exploit code for this remote code execution vulnerability has been made publicly available. Unit 42 first observed scanning traffic early on March 30, 2022 with HTTP requests to servers that included the test strings within the URL. Figure 10 shows an example of the early scanning activity. 041b061a72
