| Title | Tenda Tenda M3 Access Controller(M3) V1.0.0.10 Buffer Overflow |
|---|
| Description | A serious buffer overflow vulnerability exists in the setAdvPolicyData function of Tenda M3 V1.0.0.10 firmware, specifically in its subroutine sub_648D4. The vulnerability is caused by the following unsafe code logic:
strncpy(dest, src, v16 - src);
The copy length v16 - src is directly calculated from user-controlled input, while the program does not properly validate the actual size of the destination buffer dest. As a result, an attacker can craft malicious parameters to trigger a buffer overflow and cause denial of service (DoS) or other security impacts. |
