AI Analysis
Technical Summary
Shenzhen Tenda Technology Co., Ltd's Tenda O3 Wireless Router version 1.0.0.5(4180) contains multiple stack overflow vulnerabilities in the fromVirtualSer function. The vulnerabilities are exploitable through the parameters puVar2, puVar1, __s2, __s1_00, and puVar3 by sending crafted HTTP requests. Successful exploitation results in a Denial of Service condition. There is no CVSS score or vendor advisory indicating remediation status.
Potential Impact
An attacker can cause a Denial of Service on affected devices by exploiting stack overflow vulnerabilities via crafted HTTP requests. This disrupts normal router operation, potentially impacting network availability for users relying on the device.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, affected devices should be isolated from untrusted networks to reduce exposure to crafted HTTP requests targeting the vulnerability.
