CVSS v3.1 |
| A command injection vulnerability was identified in TP-Link TL-WR802N v4, TL-WR841N v14, and TL-WR840N v6 due to improper neutralization of special elements used in an OS command. In the router configuration import function allows an authenticated attacker to upload a crafted configuration file that results in execution of OS commands with root privileges during port-trigger processing.
Successful exploitation allows an authenticated attacker to execute system commands with root privileges, leading to full device compromise. |
| TP-Link TL-WR841N ated_tp Command Injection Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link TL-WR841N routers. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the ated_tp service. The issue results from the lack of proper validation of a user-supplied string before using it to execute a system call. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-21825. |
| Cross-site request forgery (CSRF) vulnerability in the administration console in TP-Link TL-WR840N (V1) router with firmware before 3.13.27 build 141120 allows remote attackers to hijack the authentication of administrators for requests that change router settings via a configuration file import. |
| TP-Link TL-WR840N EU v6.20 was discovered to contain insecure protections for its UART console. This vulnerability allows attackers to connect to the UART port via a serial connection and execute commands as the root user without authentication. |
| TP-LINK TL-WR840N(ES)_V6.20 was discovered to contain a buffer overflow via the X_TP_ClonedMACAddress parameter. |
| TP-LINK TL-WR840N(ES)_V6.20 was discovered to contain a buffer overflow via the httpRemotePort parameter. |
| TP-LINK TL-WR840N(ES)_V6.20 was discovered to contain a buffer overflow via the minAddress parameter. |
| TP-LINK TL-WR840N(ES)_V6.20 was discovered to contain a buffer overflow via the DNSServers parameter. |
| TP-LINK TL-WR840N(ES)_V6.20_180709 was discovered to contain a remote code execution (RCE) vulnerability via the function oal_wan6_setIpAddr. |
| TP-LINK TL-WR840N(ES)_V6.20_180709 was discovered to contain an integer overflow via the function dm_checkString. This vulnerability allows attackers to cause a Denial of Service (DoS) via a crafted HTTP request. |
| TP-LINK TL-WR840N(ES)_V6.20_180709 was discovered to contain a command injection vulnerability via the component oal_setIp6DefaultRoute. |
| TP-LINK TL-WR840N(ES)_V6.20_180709 was discovered to contain a command injection vulnerability via the component oal_startPing. |
| Tp-Link TL-WR840N (EU) v6.20 Firmware (0.9.1 4.17 v0001.0 Build 201124 Rel.64328n) is vulnerable to Buffer Overflow via the Password reset feature. |
| The PING function on the TP-Link TL-WR840N EU v5 router with firmware through TL-WR840N(EU)_V5_171211 is vulnerable to remote code execution via a crafted payload in an IP address input field. |
| In TP-Link Wireless N Router WR840N an ARP poisoning attack can cause buffer overflow |
| oal_ipt_addBridgeIsolationRules on TP-Link TL-WR840N 6_EU_0.9.1_4.16 devices allows OS command injection because a raw string entered from the web interface (an IP address field) is used directly for a call to the system library function (for iptables). NOTE: oal_ipt_addBridgeIsolationRules is not the only function that calls util_execSystem. |
| The traceroute function on the TP-Link TL-WR840N v4 router with firmware through 0.9.1 3.16 is vulnerable to remote code execution via a crafted payload in an IP address input field. |
| TP-Link TL-WR840N v5 00000005 devices allow XSS via the network name. The attacker must log into the router by breaking the password and going to the admin login page by THC-HYDRA to get the network name. With an XSS payload, the network name changed automatically and the internet connection was disconnected. All the users become disconnected from the internet. |
| TP-Link TL-WR840N devices allow remote attackers to cause a denial of service (networking outage) via fragmented packets, as demonstrated by an "nmap -f" command. |
| TP-Link WR840N devices have a buffer overflow via a long Authorization HTTP header. |
