CVE-2013-10048: D-Link DIR-300 Firmware

Critical severity, CVSS 9.8. EPSS: 17.1% chance of exploitation in the next 30 days.

An OS command injection vulnerability exists in various legacy D-Link routers—including DIR-300 rev B and DIR-600 (firmware ≤ 2.13 and ≤ 2.14b01, respectively)—due to improper input handling in the unauthenticated command.php endpoint. By sending specially crafted POST requests, a remote attacker can execute arbitrary shell commands with root privileges, allowing full takeover of the device. This includes launching services such as Telnet, exfiltrating credentials, modifying system configuration, and disrupting availability. The flaw stems from the lack of authentication and inadequate sanitation of the cmd parameter.

Affected products

• D-Link DIR-300 Firmware: up to and including 2.13
• D-Link DIR-600 Firmware: up to and including 2.14b01
