Severity ?
5.3 (Medium) - CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N
CWE
  • CWE-120 - Buffer Copy without Checking Size of Input
Summary
A buffer overflow vulnerability exists in the embedded HTTP service in TL-WR841N v14 when processing multipart/form-data requests. Insufficient validation of an attacker-controlled boundary parameter may allow a remote unauthenticated attacker to submit a crafted request that corrupts memory by overwriting data beyond the bounds of an internal buffer. Successful exploitation may result in modification or corruption of process memory, potentially leading to undefined application behavior. Arbitrary code execution, information disclosure, and denial-of-service conditions have not been demonstrated.

CWE
  • CWE-476 - NULL pointer dereference
Summary
A NULL pointer dereference vulnerability exists in TL-WR841N v14 in the UPnP service when processing SOAP state variable query requests. A specially crafted SOAP query may trigger unexpected termination or instability of the process hosting the UPnP service. Successful exploitation may result in a denial-of-service condition affecting UPnP discovery, state query, or related management functionality until the affected process is restarted or the device is rebooted.
