CVE-2025-15008 is a stack-based buffer overflow vulnerability identified in the Tenda WH450 router firmware version 1.0.0.18. The flaw exists in the HTTP request handler component, specifically in the processing of the 'page' argument within the /goform/L7Port endpoint. When an attacker sends a specially crafted HTTP request manipulating this argument, it causes a buffer overflow on the stack, which can lead to arbitrary code execution or a denial of service condition. The vulnerability is remotely exploitable without requiring authentication or user interaction, making it accessible to attackers over the network. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and partial impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). Although the severity is rated medium (6.9), the availability of a public exploit increases the urgency for remediation. No official patches or updates have been released by Tenda at the time of publication. The vulnerability affects only version 1.0.0.18 of the WH450 firmware, and no other versions or products are currently reported as impacted. The lack of known exploits in the wild suggests limited active exploitation, but the public exploit availability raises the risk of future attacks. The vulnerability's exploitation could allow attackers to gain control over the device, intercept or manipulate network traffic, or disrupt network services.

The exploitation of CVE-2025-15008 could have significant consequences for organizations using the Tenda WH450 router with the vulnerable firmware. Successful exploitation may lead to remote code execution, allowing attackers to take full control of the device. This can result in interception or manipulation of network traffic, potentially compromising sensitive data confidentiality and integrity. Additionally, attackers could disrupt network availability by causing device crashes or denial of service. Compromised routers can also serve as footholds for lateral movement within internal networks or as launch points for further attacks such as botnet participation or data exfiltration. Given that the vulnerability requires no authentication and no user interaction, it presents a high risk of automated exploitation, especially with the public exploit available. Organizations relying on these devices for critical network infrastructure may face operational disruptions and increased exposure to cyber threats. The impact extends beyond individual devices to the broader network security posture, potentially affecting connected systems and users.

1. Immediately isolate vulnerable Tenda WH450 devices from untrusted networks, especially the internet, to prevent remote exploitation. 2. Disable remote management and any unnecessary services on the affected routers to reduce the attack surface. 3. Implement network segmentation to limit access to the devices from critical internal networks. 4. Monitor network traffic for suspicious HTTP requests targeting the /goform/L7Port endpoint, particularly those manipulating the 'page' argument. 5. Apply strict firewall rules to block unauthorized access to router management interfaces. 6. Contact Tenda support or monitor official channels for firmware updates or patches addressing CVE-2025-15008 and apply them promptly once available. 7. Consider replacing vulnerable devices with models that have a proven security track record if patches are delayed. 8. Conduct regular security assessments and penetration testing to detect potential exploitation attempts. 9. Educate network administrators about this vulnerability and the importance of timely mitigation. 10. Maintain up-to-date backups of router configurations to facilitate recovery in case of compromise.
