PoC Exploit Released for Arbitrary File Write Flaw (CVE-2024-22263) in Spring Cloud Data Flow
Security researcher Zeyad Azima from SecureLayer7 published the proof-of-concept exploit for arbitrary file write vulnerability (CVE-2024-22263) in Spring Cloud Data Flow, a widely-used tool for cloud-based data processing. The flaw allows unauthorized users to write arbitrary files to any location on the file system, potentially compromising the entire server.
CVE-2024-22263 is an Arbitrary File Write Vulnerability affecting Spring Cloud Data Flow, specifically within its Skipper server component. The Skipper server, responsible for handling package uploads, fails to properly sanitize the upload path. This oversight allows an attacker with access to the Skipper server API to craft a malicious upload request, enabling them to write files to arbitrary locations on the server’s file system. The consequences of such an exploit could be severe, potentially leading to server compromise or further exploitation.
The vulnerability affects several versions of Spring Cloud Skipper, including 2.11.0 to 2.11.2 and 2.10.x. The Spring team has released a patched version, 2.11.3, and strongly recommends that all users upgrade to this version as soon as possible.
While the release of the PoC exploit on GitHub has brought critical attention to the CVE-2024-22263 vulnerability, it also presents a significant risk. Threat actors could potentially use the publicly available exploit to target unpatched systems. This underscores the urgency for organizations to apply the necessary updates and protect their environments from exploitation.
