Vulnerability Note VU#572615
Original Release Date: 2023-01-17 | Last Revised: 2023-01-17

Overview
TP-Link router WR710N-V1-151022 running firmware published 2015-10-22 and Archer-C5-V2-160201 running firmware published 2016-02-01 are susceptible to two vulnerabilities:

A buffer overflow during HTTP Basic Authentication allowing a remote attacker to corrupt memory allocated on a heap causing denial of service or arbitrary code execution;

A side-channel attack via a strcmp() function in the HTTP daemon allowing deterministic guessing of each byte of a username and password input during authentication.

Description
TP-Link device WR710N-V1-151022 is a 150Mbps Wireless N Mini Pocket router, and Archer-C5-V2-160201 is a Wireless Dual Band Gigabit router. These SOHO devices are sold by TP-Link and their latest firmware available as of January 11, 2023, have two vulnerabilities.

CVE-2022-4498 When receiving user input during HTTP Basic Authentication mode, a crafted packet may cause a heap overflow in the httpd daemon. This can lead to denial of service (DoS) if the httpd process crashes or arbitrary remote code execution (RCE).

CVE-2022-4499 A strcmp() function in httpd, is susceptible to a side-channel attack when used to verify usename and password credentials. By measuring the response time of the vulnerable process, each byte of the username and password strings may be easier to guess.
