CVE-2026-38835: n/a
A critical command injection vulnerability exists in Tenda W30E V2. 0 firmware version 16. 01. 0. 21 within the formSetUSBPartitionUmount function via the usbPartitionName parameter. This flaw allows unauthenticated attackers to execute arbitrary commands on the affected device by sending a specially crafted request. The vulnerability has a CVSS score of 9. 8, indicating a high impact on confidentiality, integrity, and availability. No official patch or remediation guidance is currently available from the vendor. There are no known exploits in the wild at this time.
AI Analysis
Technical Summary
CVE-2026-38835 is a command injection vulnerability affecting Tenda W30E V2.0 firmware 16.01.0.21. The issue arises in the formSetUSBPartitionUmount function, where the usbPartitionName parameter is not properly sanitized, allowing remote attackers to execute arbitrary commands without authentication. The vulnerability has a CVSS 3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), reflecting its critical severity and ease of exploitation over the network. No patch or official remediation level has been published by the vendor as of the data provided.
Potential Impact
Successful exploitation allows remote unauthenticated attackers to execute arbitrary commands on the device, potentially leading to full system compromise. This impacts the confidentiality, integrity, and availability of the affected device and any network it is connected to. Given the critical CVSS score, the vulnerability poses a severe security risk if exploited.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict network access to the affected device, especially from untrusted networks, to reduce exposure. Monitor for any updates from Tenda regarding patches or mitigations. Do not rely on generic mitigations as this vulnerability allows direct command injection via a network request.
