CVE-2005-1680

Status: ModifiedHigh (7.5)—

D-Link DSL-502T, DSL-504T, DSL-562T, and DSL-G604T, when /cgi-bin/firmwarecfg is executed, allows remote attackers to bypass authentication (1) if their IP address already exists in /var/tmp/fw_ip or (2) if their request is the first, which causes /var/tmp/fw_ip to be created and contain their IP address.

CVSS

Version: 2.0
Vector: AV:N/AC:L/Au:N/C:P/I:P/A:P
Base score: 7.5

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 1.46%
Percentile among all scored CVEs: 73
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).
