Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Requires validation of HTTP request inputs to login.cgi's Goto_chidx() function, directly preventing specially crafted requests from causing the stack-based buffer overflow.
Implements memory safeguards like stack canaries and non-executable memory to block exploitation of the stack-based buffer overflow even if invalid input reaches the vulnerable code.
Mandates timely identification, reporting, and patching of flaws such as CVE-2024-36290 in the Wavlink AC3000 firmware to eliminate the buffer overflow vulnerability.
NVD Description
A buffer overflow vulnerability exists in the login.cgi Goto_chidx() functionality of Wavlink AC3000 M33A8.V5030.210505. A specially crafted HTTP request can lead to stack-based buffer overflow. An attacker can make an unauthenticated HTTP request to trigger this vulnerability.
Deeper analysisAI
CVE-2024-36290 is a stack-based buffer overflow vulnerability (CWE-120) in the Goto_chidx() functionality of login.cgi within the Wavlink AC3000 firmware version M33A8.V5030.210505. The issue arises when processing a specially crafted HTTP request, leading to a buffer overflow condition.
An unauthenticated attacker can exploit this vulnerability remotely over the network with low attack complexity and no user interaction required. Successful exploitation triggers the stack-based buffer overflow, potentially resulting in high impacts to confidentiality, integrity, and availability, along with a change in scope, as reflected in its CVSS 3.1 base score of 10.0 (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).
