A stack-based buffer overflow vulnerability exists in the touchlist_sync.cgi touchlistsync() functionality of Wavlink AC3000 M33A8.V5030.210505. A specially crafted HTTP request can lead to arbitrary code execution. An attacker can send an HTTP request to trigger this vulnerability.
Executive ViewAI
CVE-2024-36258 presents critical security risk, a stack-based buffer overflow vulnerability rated CVSS 10.0. Exploitation could allow attackers to corrupt memory, crash the application, or potentially execute arbitrary code. With an EPSS score of 16%, exploitation is likely in exposed deployments. Organizations should apply vendor updates immediately when available and implement compensating controls in the interim.
Apply vendor patch. If immediate patching is not feasible: (1) Enable ASLR and DEP where available; (2) Implement network segmentation; (3) Monitor for exploitation indicators.
Threat Intelligence Overview
How this decision was reached
The engine reads each signal below and applies a fixed list of rules from top to bottom. The first rule that matches sets the recommended action – like a statement, every line is shown.
What every action level means
SSVC AssessmentENISA
Priority Score
Attack Technique
A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
A stack-based buffer overflow occurs when a program writes more data to a buffer located on the stack than it was allocated to hold.
Remote Code Execution represents the critical moment when an attacker successfully runs arbitrary code on a target system without physical access.
