Comprehensive Technical Analysis of EUVD-2025-29113

1. Vulnerability Assessment and Severity Evaluation

The vulnerability identified in the Mercury KM08-708H GiGA WiFi Wave2 1.1.14 involves a stack-based buffer overflow in the HTTP Header Handler component. This vulnerability is particularly severe due to its remote exploitability and the potential for significant impact on confidentiality, integrity, and availability.

Severity Evaluation:

• Base Score: 9.3 (CVSS 4.0)
• Vector String: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:P

The high base score indicates a critical vulnerability. The attack vector (AV:N) is network-based, requiring low complexity (AC:L) and no privileges (PR:N) or user interaction (UI:N). The impact on confidentiality, integrity, and availability is high (VC:H, VI:H, VA:H), and the exploit is publicly available (E:P).

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Remote Exploitation: The vulnerability can be exploited remotely over the network.
• HTTP Header Manipulation: The attack involves manipulating the "Host" argument in the HTTP header, leading to a stack-based buffer overflow.

Exploitation Methods:

• Buffer Overflow: An attacker can send a specially crafted HTTP request with an overly long "Host" header, causing a buffer overflow.
• Code Execution: The buffer overflow can potentially allow an attacker to execute arbitrary code on the affected device.
