Background
Widoco is an open-source tool used for generating documentation for ontologies. It is built using the Maven ecosystem and is widely used by developers. The tool provides a convenient way to create documentation by extracting metadata from ontologies and generating HTML pages. However, a critical vulnerability has been discovered in Widoco that allows for path traversal attacks. This vulnerability is present in the unZipIt function of the WidocoUtils.java file. An attacker can exploit this vulnerability to traverse the file system and potentially access sensitive files on the local host.
Vulnerability Detail
The vulnerability in Widoco arises from insufficient input validation in the unZipIt function. By manipulating the input, an attacker can navigate beyond the intended directory and access files outside the scope of the intended operation. This can lead to unauthorized disclosure of sensitive information or even remote code execution. The severity of this vulnerability is rated as HIGH with a CVSS score of 7.8. The Common Weakness Enumeration (CWE) identifier assigned to this vulnerability is CWE-22.
How To Fix
No fixed version is published for this vulnerability.

Workaround
As a temporary workaround, developers can implement input validation to ensure that the extracted files are within the expected directory structure. This can be achieved by checking the file paths against a whitelist of allowed directories before performing any operations on them. Here is an example of how this can be done in Java:
public boolean isValidPath(String path) {
List<String> allowedDirectories = Arrays.asList("/path/to/allowed/directory");
return allowedDirectories.stream().anyMatch(path::startsWith);
}
By validating the path before processing, the risk of path traversal attacks can be mitigated.
Conclusion
In conclusion, Widoco is affected by a critical path traversal vulnerability that can lead to unauthorized access to sensitive files. It is crucial for developers using Widoco to apply the provided patch and update their dependencies to mitigate this vulnerability. Implementing input validation can serve as a temporary workaround until the patch is applied. For further support on vulnerability remediation, please contact DevNack.com.
