TL-WR841Nv14_US_0.9.1_4.18 routers were discovered to contain a stack overflow in the function dm_fillObjByStr(). This vulnerability allows unauthenticated attackers to execute arbitrary code.

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.

This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of TP-Link TL-WR940N 3.20.1 Build 200316 Rel.34392n (5553) routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the parsing of file name extensions. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-13910.
