TP-Link AX1800 WiFi 6 Router (Archer AX21) devices allow unauthenticated attackers (on the LAN) to execute arbitrary code as root via the db_dir field to minidlnad. The attacker obtains the ability to modify files.db, and that can be used to reach a stack-based buffer overflow in minidlna-1.1.2/upnpsoap.c. Exploitation requires that a USB flash drive is connected to the router (customers often do this to make a \\192.168.0.1 share available on their local network).

Heap-based Buffer Overflow Vulnerability Leading to Denial-of-Service in TP-Link Tapo C520WS
A heap-based buffer overflow vulnerability was identified in TP-Link Tapo C520WS v2.6 within the HTTP parsing loop when appending segmented request bodies without continuous write‑boundary verification, due to insufficient boundary validation when handling externally supplied HTTP input. An attacker on the same network segment could trigger heap memory corruption conditions by sending crafted payloads that cause write operations beyond allocated buffer boundaries. Successful exploitation causes a Denial-of-Service (DoS) condition, causing the device’s process to crash or become unresponsive.
Heap-based Buffer Overflow Vulnerability Leading to Denial-of-Service in TP-Link Tapo C520WS
A heap-based buffer overflow vulnerability was identified in TP-Link Tapo C520WS v2.6 within the asynchronous parsing of local video stream content due to insufficient alignment and validation of buffer boundaries when processing streaming inputs.An attacker on the same network segment could trigger heap memory corruption conditions by sending crafted payloads that cause write operations beyond allocated buffer boundaries. Successful exploitation causes a Denial-of-Service (DoS) condition, causing the device’s process to crash or become unresponsive.
Stack-based Buffer Overflow Leading to Denial of Service in TP-Link Tapo C520WS
A stack-based buffer overflow vulnerability was identified in TP-Link Tapo C520WS v2.6 within a configuration handling component due to insufficient input validation. An attacker can exploit this vulnerability by supplying an excessively long value for a vulnerable configuration parameter, resulting in a stack overflow. Successful exploitation results in Denial-of-Service (DoS) condition, leading to a service crash or device reboot, impacting availability.
Denial of Service via Path Expansion Overflow in HTTP Service in TP-Link Tapo C520WS
A denial-of-service vulnerability was identified in TP-Link Tapo C520WS v2.6 within the HTTP request path parsing logic. The implementation enforces length restrictions on the raw request path but does not account for path expansion performed during normalization. An attacker on the adjacent network may send a crafted HTTP request to cause buffer overflow and memory corruption, leading to system interruption or device reboot.
Remote Code Execution via Stack-based Buffer Overflow in ONVIF SOAP Parser in TP-Link Tapo C200 and C520WS
A stack-based buffer overflow vulnerability was identified in the ONVIF SOAP XML Parser in Tapo C200 v3 and C520WS v2.6. When processing XML tags with namespace prefixes, the parser fails to validate the prefix length before copying it to a fixed-size stack buffer. It allowed a crafted SOAP request with an oversized namespace prefix to cause memory corruption in stack. An unauthenticated attacker on the same local network may exploit this flaw to enable remote code execution with elevated privileges, leading to full compromise of the device.
Authenticated Command Injection in mcsd Service of TP-Link Archer AX53
A command injection vulnerability on AX53 v1 occurs in mscd debug functionality due to insufficient input handling, allowing log redirection to arbitrary files and concatenation of unvalidated file content into shell commands, enabling authenticated attackers to inject and execute arbitrary commands. Successful exploitation may allow execution of malicious commands and ultimately full control of the device.
Command Injection Vulnerability in Telnet CLI on TP-Link TL-MR6400
A command injection vulnerability has been identified in the Telnet command-line interface (CLI) of TP-Link TL-MR6400 v5.3. This issue is caused by insufficient sanitization of data processed during specific CLI operations. An authenticated attacker with elevated privileges may be able to execute arbitrary system commands. Successful exploitation may lead to full device compromise, including potential loss of confidentiality, integrity, and availability.
Input Validation Vulnerability on Multiple Omada Switches
The web interface on multiple Omada switches does not adequately validate certain external inputs, which may lead to out-of-bound memory access when processing crafted requests.
