CVE-2014-4688

Status: ModifiedMedium (6.5)—💥 Exploit

pfSense before 2.1.4 allows remote authenticated users to execute arbitrary commands via (1) the hostname value to diag_dns.php in a Create Alias action, (2) the smartmonemail value to diag_smart.php, or (3) the database value to status_rrd_graph_img.php.

CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:S/C:P/I:P/A:P
Base score: 6.5

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 6.97%
Percentile among all scored CVEs: 94
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.
