CVE-2005-0256
The wu_fnmatch function in wu_fnmatch.c in wu-ftpd 2.6.1 and 2.6.2 allows remote attackers to cause a denial of service (CPU exhaustion by recursion) via a glob pattern with a large number of * (wildcard) characters, as demonstrated using the dir command.
Does this matter?
A public exploit is published in Exploit-DB (verified), so the technical barrier is gone even though the severity is medium and EPSS is 5.2%. Treat it as high on anything reachable from the internet.
