CWE-264Published: December 25, 2011· Updated: Jun 16, 2026
10.0
CVSS v3.1
Official Description
apps/a3/cfg_ethping.cgi in the Ctek SkyRouter 4200 and 4300 allows remote attackers to execute arbitrary commands via shell metacharacters in the PINGADDRESS parameter for a "u" action.
Technical Analysis
CVE-2011-5010 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-2011-5010. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
