Exploitability
| CWE ID | Description |
|---|---|
| CWE-22 | The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory. |

AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2026-3405 is a path traversal vulnerability found in thinkgem JeeSite versions up to 5.15.1, specifically in an unknown function of the Connection Handler component.
This vulnerability occurs because the product does not properly sanitize external input used to build file or directory pathnames, allowing an attacker to manipulate the pathname to access files or directories outside the intended restricted directory.
The attack can be initiated remotely, but it is considered to have high complexity and difficult exploitability.
How can this vulnerability impact me? :
This vulnerability can impact you by allowing an attacker to read arbitrary files on the server, potentially exposing sensitive information.
Because the attacker can traverse directories outside the intended scope, confidential files such as system configuration files could be accessed.
The exploit is publicly available, and although difficult to exploit, successful attacks could compromise confidentiality.
No known mitigations or fixes have been provided by the vendor, so the recommended action is to replace the affected product with an alternative.
How does this vulnerability affect compliance with common standards and regulations (like GDPR, HIPAA)?:
I don't know
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability involves manipulation of JDBC connection parameters leading to path traversal and potentially arbitrary file read or remote code execution. Detection would involve monitoring for suspicious JDBC URL patterns or connection attempts that include unusual or malformed driver class names or URLs.
Since the vulnerability exploits the Connection Handler component with crafted JDBC URLs, network detection could focus on identifying connections to rogue or unexpected MySQL servers or unusual JDBC URL parameters.
No specific detection commands or signatures are provided in the available resources.
What immediate steps should I take to mitigate this vulnerability?
No official fixes or mitigations have been provided by the vendor, as they did not respond to the disclosure.
Immediate mitigation steps include replacing the affected product (thinkgem JeeSite up to version 5.15.1) with an alternative solution that is not vulnerable.
Additionally, restricting network access to the application and monitoring for suspicious JDBC connection attempts may help reduce risk.
