High
7.8/10

Summary

Buffer overflow in ACME micro_httpd, as used in D-Link DSL2750U and DSL2740U and NetGear WGR614 and MR-ADSL-DG834 routers allows remote attackers to cause a denial of service (crash) via a long string in the URI in a GET request.

CWE-119 - Buffer Overflow

Buffer overflow attacks involve data transit and operations exceeding the restricted memory buffer, thereby corrupting or overwriting data in adjacent memory locations. Such overflow allows the attacker to run arbitrary code or manipulate the existing code to cause privilege escalation, data breach, denial of service, system crash and even complete system compromise. Given that languages such as C and C++ lack default safeguards against overwriting or accessing data in their memory, applications utilizing these languages are most susceptible to buffer overflows attacks.
