This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of TP-Link TL-WR841N 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 improper authentication. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise.

(dot dot) in the PATHINFO to login/.

TP-Link TL-WR740N V1 and V2 v3.12.4 and earlier allows authenticated attackers to execute arbitrary code or cause a Denial of Service (DoS) via uploading a crafted firmware image during the firmware update process.

An infinite loop in the function httpRpmPass of TP-Link TL-WR741N/TL-WR742N V1/V2/V3130415 allows attackers to cause a Denial of Service (DoS) via a crafted packet.
