CVE-2009-2765
CWE-20Published: August 14, 2009· Updated: Jun 16, 2026
8.3
CVSS v3.1
Official Description
httpd.c in httpd in the management GUI in DD-WRT 24 sp1, and other versions before build 12533, allows remote attackers to execute arbitrary commands via shell metacharacters in a request to a cgi-bin/ URI.
Technical Analysis
CVE-2009-2765 requires adjacent network access, limiting remote exploitation but still posing risk in shared or local network environments.
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-2009-2765. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
