Comprehensive Technical Analysis of EUVD-2025-204300
1. Vulnerability Assessment and Severity Evaluation
The vulnerability EUVD-2025-204300 affects the Tenda WH450 router, specifically version 1.0.0.18. The flaw resides in the HTTP Request Handler component, particularly in the file /goform/wirelessRestart. The manipulation of the argument GO results in a stack-based buffer overflow, which can be exploited remotely.
Severity Evaluation:
- CVSS Base Score: 9.3 (Critical)
- CVSS Vector: 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 due to the following factors:
- Attack Vector (AV:N): Network, meaning the vulnerability can be exploited remotely.
- Attack Complexity (AC:L): Low, indicating that the attack is relatively straightforward to execute.
- Privileges Required (PR:N): None, meaning no special privileges are needed to exploit the vulnerability.
- User Interaction (UI:N): None, indicating that no user interaction is required for the attack to succeed.
- Confidentiality (VC:H), Integrity (VI:H), and Availability (VA:H): All high, indicating significant impact on all three aspects of the CIA triad.
2. Potential Attack Vectors and Exploitation Methods
Attack Vectors:
- Remote Exploitation: The vulnerability can be exploited over the network, making it accessible to attackers from anywhere in the world.
- HTTP Request Manipulation: The attacker can send specially crafted HTTP requests to the vulnerable endpoint
/goform/wirelessRestartwith a manipulatedGOargument to trigger the buffer overflow.
Exploitation Methods:
- Buffer Overflow: By sending a large payload in the
GOargument, the attacker can cause a stack-based buffer overflow, potentially leading to arbitrary code execution. - Public Exploit Availability: The exploit has been released to the public, increasing the likelihood of widespread attacks.
