Severity ?

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.

CWE
  • CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Summary
An OS Command Injection vulnerability in TP-Link Archer BE230 v1.2(vpn modules) allows adjacent authenticated attacker execute arbitrary code. Successful exploitation could allow an attacker to gain full administrative control of the device, resulting in severe compromise of configuration integrity, network security, and service availability. This CVE covers one of multiple distinct OS command injection issues identified across separate code paths. Although similar in nature, each instance is tracked under a unique CVE ID.This issue affects Archer BE230 v1.2 < 1.2.4 Build 20251218 rel.70420.
