This vulnerability, known as \"Spring4Shell,\" can be exploited by sending crafted queries to a server running the Spring Core framework. Hackers are actively exploiting this flaw to execute malicious Java code on vulnerable servers. Initial exploit attempts were observed targeting a honeypot on port 9001. The exploit modifies logging configurations to create a webshell by writing code to a log file, which is then executed via a browser. Although there is scanning activity for vulnerable hosts, the exploitation is less widespread compared to Log4Shell, as it requires specific conditions beyond just using the framework.","references":["https://isc.sans.edu/diary/Spring+Vulnerability+Update+Exploitation+Attempts+CVE202222965/28504","https://www.rapid7.com/blog/post/2022/03/30/spring4shell-zero-day-vulnerability-in-spring-framework/","https://www.microsoft.com/en-us/security/blog/2022/04/04/springshell-rce-vulnerability-guidance-for-protecting-against-and-detecting-cve-2022-22965/","https://www.sentinelone.com/blog/cve-2022-22963/"],"status":"complete","source_file":"kev-07.28.2025_attack-16.1-enterprise.json","attack_version":"16.1","kev_snapshot":"07/28/2025"},{"domain":"enterprise","cve":"CVE-2022-22963","technique":"T1059.007","technique_name_at_mapping":"JavaScript","mapping_type":"primary_impact","capability_group":"code_execution","comments":"In certain versions of Spring Cloud Function, a vulnerability allows remote code execution through a specially crafted Spring Expression Language (SpEL) routing expression.
