Low risk30th percentile - higher than 30% of all known CVEs
Summary
In kerwincui FastBee up to 1.2.1, the ToolController.download function in ToolController.java of the Tool Download Endpoint component, when manipulating the fileName argument, leads to path traversal. The attack can be performed remotely and the exploit has been publicly disclosed. The vendor did not respond to the disclosure.
Risk Assessment
An attacker could remotely read files outside the intended directory, potentially exposing sensitive data or configuration. This may lead to further attacks on the system.
Recommendation
Until a fix is released, restrict access to the tool download endpoint or implement validation of the fileName parameter. Monitor the project for updates.
