VAR-202301-0769

Vulnerability from variot - Updated: 2023-12-18 11:55

TP-Link routers, Archer C5 and WR710N-V1, using the latest software, the strcmp function used for checking credentials in httpd, is susceptible to a side-channel attack. By measuring the response time of the httpd process, an attacker could guess each byte of the username and password. 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:CVE-2022-4498 Unknown CVE-2022-4499 UnknownCVE-2022-4498 Unknown CVE-2022-4499 Unknown. TP-Link router Archer C5 and WR710N-V1 Exists in observable mismatch vulnerabilities.Information may be obtained
