Path Traversal in feiyuchuixue sz-boot-parent API Allows Remote Exploitation

Publication date: 2026-02-25

Last updated on: 2026-04-29

Assigner: VulDB

Description
A security flaw has been discovered in feiyuchuixue sz-boot-parent up to 1.3.2-beta. This affects an unknown part of the file /api/admin/common/download/templates of the component API. Performing a manipulation of the argument templateName results in path traversal. Remote exploitation of the attack is possible. The exploit has been released to the public and may be used for attacks. Upgrading to version 1.3.3-beta is able to mitigate this issue. The patch is named aefaabfd7527188bfba3c8c9eee17c316d094802. It is recommended to upgrade the affected component. The project was informed beforehand and acted very professional: "We have implemented path validity checks on parameters for the template download interface (...)"

Executive Summary

CVE-2026-3188 is a path traversal vulnerability in the feiyuchuixue sz-boot-parent project up to version 1.3.2-beta. It affects the API endpoint /api/admin/common/download/templates, where the templateName parameter is used to build a file path without proper validation. This allows an attacker to manipulate the templateName argument with directory traversal sequences like ../ to access files outside the intended templates directory.

Because of this flaw, an attacker can remotely read arbitrary resource files on the server, potentially exposing sensitive information. The vulnerability can be exploited without authentication, and a public exploit is available.

Impact Analysis

This vulnerability can impact you by allowing unauthorized remote attackers to read arbitrary files on the server hosting the vulnerable application. This can lead to exposure of sensitive or confidential information stored on the server.

Since the exploit is easy to execute and publicly available, it increases the risk of data leakage or information disclosure, which can compromise the confidentiality of your system.

Detection Guidance

[{'type': 'paragraph', 'content': 'This vulnerability can be detected by testing the API endpoint /api/admin/common/download/templates for path traversal attempts by manipulating the templateName parameter.'}, {'type': 'paragraph', 'content': 'A common detection method is to send crafted HTTP requests with directory traversal sequences such as ../ in the templateName parameter to see if files outside the intended directory can be accessed.'}, {'type': 'list_item', 'content': 'Example curl command to test for path traversal:'}, {'type': 'list_item', 'content': 'curl -v "http://<target-host>/api/admin/common/download/templates?templateName=../../../../etc/passwd"'}, {'type': 'list_item', 'content': 'If the response contains contents of sensitive files (e.g., /etc/passwd), the vulnerability is present.'}] [1, 2]

Mitigation Strategies

The recommended immediate mitigation is to upgrade the affected component feiyuchuixue sz-boot-parent to version 1.3.3-beta or later, which includes a patch that implements path validity checks on the template download interface.

Until the upgrade can be applied, consider restricting access to the vulnerable API endpoint and monitoring for suspicious requests containing directory traversal patterns.
