VAR-200602-0268

Vulnerability from variot - Updated: 2025-04-03 22:16

D-Link DWL-G700AP with firmware 2.00 and 2.01 allows remote attackers to cause a denial of service (CAMEO HTTP service crash) via a request composed of "GET" followed by a space and two newlines, possibly triggering the crash due to missing arguments. D-Link DWL-G700AP is a wireless access router.

D-Link DWL-G700AP's HTTP management interface implementation has a vulnerability. A remote attacker could use this vulnerability to cause the HTTP server to become unresponsive.

If you want to configure DWL-G700AP, you must go through the http service, and this service is managed by httpd named CAMEO. A denial of service vulnerability exists in this webserver. An attacker just sending a "GET \ n \ n" string can cause the service to crash. D-Link DWL-G700AP HTTPD is prone to a remote denial-of-service vulnerability. This issue is due to a failure in the 'httpd' service to properly handle malformed data. An attacker can exploit this issue to crash the affected webserver, effectively denying service to legitimate users. The affected device must be manually reset to restart the affected service. This issue is reported to affect firmware versions 2.00 and 2.01; other firmware versions may also be vulnerable.

TITLE: DWL-G700AP Web Interface Denial of Service

SECUNIA ADVISORY ID: SA18932

VERIFY ADVISORY: http://secunia.com/advisories/18932/

CRITICAL: Less critical

IMPACT: DoS

WHERE:

From local network

OPERATING SYSTEM: D-Link DWL-G700AP http://secunia.com/product/8121/

DESCRIPTION: l0om has reported a vulnerability in D-Link DWL-G700AP, which can be exploited by malicious people to cause a DoS (Denial of Service).

The vulnerability is caused due to an error in the web-based management interface and can be exploited to crash the service via a malformed HTTP request with no resource specified.

SOLUTION: Restrict access to the web interface.

PROVIDED AND/OR DISCOVERED BY: l0om
