CVE-2020-15101
LOW2.8EPSS 0.17%freewvs's nested directory structure can interrupt scan
Published: 8/30/2024Modified: 3/13/2026
Description
### 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.
