A vulnerability has been found in TP-Link TL-WR940N V4 and TL-WR841N V11. Affected by this issue is some unknown functionality of the file /userRpm/WanSlaacCfgRpm.htm, which may lead to buffer overflow. The attack may be launched remotely. This vulnerability only affects products that are no longer supported by the maintainer.

TP-Link TL-WR940N V3 and V4 with firmware 3.16.9 and earlier contain a buffer overflow via the dnsserver1 and dnsserver2 parameters at /userRpm/Wan6to4TunnelCfgRpm.htm. This vulnerability allows an authenticated attacker to execute arbitrary code on the remote device in the context of the root user.

TP-Link TL-WR940N V4 3.16.9 and earlier allows authenticated attackers to cause a Denial of Service (DoS) via uploading a crafted firmware image during the firmware update process.

TP-Link router TL-WR940N V6 3.19.1 Build 180119 uses a deprecated MD5 algorithm to hash the admin password used for basic authentication.

This vulnerability allows network-adjacent attackers to disclose sensitive information 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 httpd service, which listens on TCP port 80 by default. The issue results from the lack of proper access control. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise. Was ZDI-CAN-13911.

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 required to exploit this vulnerability. The specific flaw exists within the httpd service, which listens on TCP port 80 by default. 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.
