CVE-2026-10192

### 1. Plain-Language Summary Attackers can remotely crash the Tenda W12 router or potentially take it over by sending a specially crafted time setting to the device's web interface. This happens because the router fails to properly check the size of the time input, causing a buffer overflow in its web service. ### 2. Affected Products * **Product:** Tenda W12 Wireless Router * **Affected Firmware Version:** 3.0.0.7(4763) *(Note: Other versions of the Tenda W12 *may* also be vulnerable, but only this specific version is explicitly confirmed in the CVE details.)* ### 3. Attacker Impact if Exploited * **Remote Code Execution (RCE):** Attackers could gain full control of the router, allowing them to intercept network traffic, change settings, or use the device as part of a botnet. * **Denial of Service (DoS):** The attack could crash the router's web service or the entire device, disrupting network connectivity for all users. ### 4. Recommended Remediation Steps 1. **Patch Immediately:** Check the Tenda website for a firmware update addressing CVE-2026-10192. Apply it as soon as available. 2. **Isolate if Unpatched:** If no patch exists, disable remote management access to the router and place it in a separate network segment (e.g., a DMZ) to limit exposure. 3. **Consider Replacement:** If no patch is planned and the device cannot be adequately segmented, replace the vulnerable router with a supported, actively patched device. 4. **Monitor Exploits:** Be aware that a public exploit exists, increasing the likelihood of attacks targeting this vulnerability.
