AI Analysis

Impact

A path traversal vulnerability exists in the ToolController.download function of kerwincui FastBee up to version 1.2.1. By manipulating the fileName argument, an attacker can reference files outside the intended repository or application directory. This flaw can lead to the disclosure of arbitrary files on the server, compromising system confidentiality. The vulnerability is not described as causing denial of service or code execution but permits reading sensitive data if the file system permissions allow it.

Affected Systems

Product: kerwincui FastBee, affected releases: 1.2.1 and all lower versions. The flaw is located in the download endpoint of the Tool Download interface within the FastBee Open API component.

Risk and Exploitability

The CVSS score of 5.3 indicates moderate severity, and the EPSS score is not available, implying no measured public exploitation trend. The vulnerability is publicly known and can be triggered remotely via the download endpoint, so the attack vector is network-based. While not listed in CISA KEV, the public availability of exploits and the ability to access arbitrary files suggest a realistic risk of confidential data leakage.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Apply the vendor‑issued patch for FastBee 1.2.1 or later once it becomes available.
  • If a patch is not yet released, implement input validation on the fileName parameter: reject any value containing "/..", backslashes, or absolute path characters and restrict it to a whitelist of allowed filenames or directory patterns.
  • Configure the web application firewall or reverse proxy to block requests to the download endpoint that include suspicious path traversal patterns such as ".." or multiple consecutive slashes.
