CVE-2008-4133
CWE-20Published: September 19, 2008· Updated: Jun 16, 2026
4.3
CVSS v3.1
Official Description
The web proxy service on the D-Link DIR-100 with firmware 1.12 and earlier does not properly filter web requests with large URLs, which allows remote attackers to bypass web restriction filters.
Technical Analysis
CVE-2008-4133 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A proof-of-concept (PoC) exploit exists for CVE-2008-4133. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
