Vulnerability from github – Published: 2024-08-30 18:43 – Updated: 2024-08-30 18:43

Summary

freewvs's nested directory structure can interrupt scan

Details

Impact

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.

Patches

This has been fixed in this commit by limiting the recursion to 500 directories: https://github.com/schokokeksorg/freewvs/commit/83a6b55c0435c69f447488b791555e6078803143

This issue was discovered by Hanno Böck.

CVE-2020-15101 (GCVE-0-2020-15101)

Vulnerability from cvelistv5 – Published: 2020-07-14 21:35 – Updated: 2024-08-04 13:08

Title

Nested directory structure can lead to Uncontrolled Resource Consumption in freewvs

Summary

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.

Severity

2.8 (Low)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
