Detailsinfo

A vulnerability was found in freewvs up to 0.1.0 and classified as problematic. Affected by this issue is the function os.walk of the component python. The manipulation with an unknown input leads to a resource consumption vulnerability. Using CWE to declare the problem leads to CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. Impacted is availability. CVE summarizes:

In freewvs before 0.1.1, a directory structure of more than 1000 nested directories can interrupt a freewvs scan due to Python's recursion limit and os.walk(). This can be problematic in a case where an administrator scans the dirs of potentially untrusted users. This has been patched in 0.1.1.

The weakness was released 07/14/2020 (GitHub Repository). The advisory is shared for download at github.com. This vulnerability is handled as CVE-2020-15101 since 06/25/2020. The attack needs to be approached locally. A simple authentication is needed for exploitation. Successful exploitation requires user interaction by the victim. There are known technical details, but no exploit is available.

Upgrading to version 0.1.1 eliminates this vulnerability.
