CVE-2022-45802 in StreamPark
Summary
by MITRE • 05/01/2023
Streampark allows any users to upload a jar as application, but there is no mandatory verification of the uploaded file type, causing users to upload some high-risk files, and may upload them to any directory, Users of the affected versions should upgrade to Apache StreamPark 2.0.0 or later

The vulnerability identified as CVE-2022-45802 affects Apache StreamPark versions prior to 2.0.0, presenting a critical security flaw in the application's file upload mechanism. This weakness stems from the absence of mandatory file type verification during the upload process, allowing any user to submit jar files without proper validation. The flaw creates an environment where malicious actors can exploit the system by uploading potentially harmful files that could compromise the entire platform's integrity.
The technical implementation of this vulnerability resides in the application's lack of input sanitization and validation controls. When users upload jar files through the Streampark interface, the system fails to perform mandatory checks on the file content or extension, enabling arbitrary file uploads. This issue directly maps to CWE-434, which describes the insecure upload of executable files, and aligns with ATT&CK technique T1195.002, focusing on the upload of malicious files for execution. The absence of file type verification creates a pathway for attackers to bypass security controls and potentially execute unauthorized code within the application's environment.
The operational impact of this vulnerability extends beyond simple file upload capabilities, as it enables privilege escalation and potential system compromise. Attackers can upload malicious jar files that may contain backdoors, malware, or other harmful code that gets executed within the StreamPark environment. Since there are no restrictions on upload directories, these files can be placed anywhere within the system, potentially leading to complete system takeover or data exfiltration. The vulnerability affects the confidentiality, integrity, and availability of the affected systems, making it particularly dangerous for production environments where StreamPark manages critical data processing operations.
Organizations utilizing affected versions of Apache StreamPark should immediately implement the recommended upgrade to version 2.0.0 or later, which includes proper file type validation and upload restrictions. Additional mitigations should include implementing strict file extension filtering, content-based file validation, and restricting upload directories to prevent arbitrary file placement. Network-level controls such as web application firewalls and intrusion detection systems can provide additional protection layers. Security teams should also conduct thorough audits of existing uploaded files and monitor for any suspicious activity related to file uploads. The fix addresses the root cause by implementing mandatory verification mechanisms that ensure only legitimate jar files are accepted, thereby preventing the exploitation of this vulnerability through unauthorized file uploads.
