CVE-2014-7859
Status: ModifiedCritical (9.8)—
Stack-based buffer overflow in login_mgr.cgi in D-Link firmware DNR-320L and DNS-320LW before 1.04b08, DNR-322L before 2.10 build 03, DNR-326 before 2.10 build 03, and DNS-327L before 1.04b01 allows remote attackers to execute arbitrary code by crafting malformed "Host" and "Referer" header values.
CVSS
- Version: 3.0
- Vector: CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
- Base score: 9.8
Exploitation probability (EPSS)
- Probability of exploitation in the next 30 days: 21%
- Percentile among all scored CVEs: 97
- Score date: 10/3/2026
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).
