Analysis

AI-generated

Technical impact

The flaw is located in the MenpiaodingdanController.java component of the Tourism‑Management‑System. By manipulating the ID, an attacker can bypass the system’s authorization checks and gain access to or modify resources that should be forbidden. The vulnerability aligns with CWE‑285 and CWE‑639, indicating that the authorization logic is incorrectly implemented. This weakness enables unauthorized users to retrieve or alter sensitive data, compromising confidentiality and integrity of the application’s managed records.

Affected Systems

The issue affects all deployed instances of jaychouchannel:Tourism‑Management‑System that have not applied the patch identified by commit d44ec3aa0bd2a72c8800e3befb0a9a96a6491b86. Version information is unavailable because the project follows a rolling‑release model, so any build prior to that commit is considered vulnerable.

Risk and Exploitability

The CVSS score is 5.3. The EPSS score is less than 1 %, indicating a very low but non‑zero exploitation probability. The exploit has been publicly disclosed and can be performed remotely by sending crafted requests with a malicious ID value. There is no indication of large‑scale exploitation yet, but the vulnerability remains actionable and requires prompt remediation to prevent unauthorized access.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Apply the patch identified by commit d44ec3aa0bd2a72c8800e3befb0a9a96a6491b86, which corrects the ID handling logic the patched application to all environments so that the authorization bypass path is eliminated
  • Implement strict input validation for the ID parameter and enforce role‑based access controls to guarantee that only users with the proper permissions can set or alter the ID argument
  • Review all other CRUD endpoints in the application for similar authorization checks and ensure they enforce proper permissions before proceeding
