CVE-2007-0247

Status: ModifiedMedium (5)—💥 Exploit

squid/src/ftp.c in Squid before 2.6.STABLE7 allows remote FTP servers to cause a denial of service (core dump) via crafted FTP directory listing responses, possibly related to the (1) ftpListingFinish and (2) ftpHtmlifyListEntry functions.

CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:N/C:N/I:N/A:P
Base score: 5

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 20%
Percentile among all scored CVEs: 97
Score date: 10/7/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
