Description
A security flaw has been discovered in Tenda WH450 1.0.0.18. This impacts an unknown function of the file /goform/wirelessRestart of the component HTTP Request Handler. The manipulation of the argument GO results in stack-based buffer overflow. The attack may be performed from remote. The exploit has been released to the public and may be used for attacks.
Comprehensive Technical Analysis of CVE-2025-14878
1. Vulnerability Assessment and Severity Evaluation
CVE ID: CVE-2025-14878
Description:
A stack-based buffer overflow vulnerability has been identified in the Tenda WH450 router, specifically in the HTTP Request Handler component. The vulnerability is triggered by manipulating the GO argument in the /goform/wirelessRestart file. This flaw allows for remote exploitation and has a CVSS score of 9.8, indicating a critical severity.
CVSS Score: 9.8
Severity Evaluation: The CVSS score of 9.8 signifies a critical vulnerability due to the following factors:
- Attack Vector: Network (Remote)
- Attack Complexity: Low
- Privileges Required: None
- User Interaction: None
- Scope: Unchanged
- Confidentiality, Integrity, and Availability Impact: High
2. Potential Attack Vectors and Exploitation Methods
Attack Vectors:
- Remote Exploitation: An attacker can exploit this vulnerability over the network without needing physical access to the device.
- HTTP Request Manipulation: The attacker can send a specially crafted HTTP request to the vulnerable endpoint (
/goform/wirelessRestart) with a manipulatedGOargument to trigger the buffer overflow.
Exploitation Methods:
- Buffer Overflow: By sending a large payload in the
GOargument, the attacker can overwrite the stack memory, potentially leading to arbitrary code execution. - Payload Delivery: The attacker can use publicly available exploit code to craft the malicious HTTP request and deliver the payload.
