The team ethical hacking by Trustwave, SpiderLabs, discovered some leaks of credentials on D-Link and Comba Telecom routers. Specifically, researcher Simon Kenin from the team found 5 such leaks, three of which concern some Comba Telecom Wi-Fi routers and the rest of the D-Link DSL modem.
When analyzing the D-Link DSL-2875AL wireless router, experts discovered that a file located at https: // [router ip address] /romfile.cfg contains the password of the device in plaintext. Thus, anyone with access to the IP address could read the files without authentication. Kenin thus assured that at least the 1.00.01 and 1.00.05 versions of the routers are definitely affected.
As the security expert said, the username and password are used by the user to connect to his ISP. This could allow a hacker to access the account ISP or the router itself if it used the same credentials.
Of course, the company was immediately notified of the vulnerability in early July, but the D-Link patch was released on 6 in September.
One of the three vulnerabilities affecting Comba routers also affects Comba AC2400. The other two vulnerabilities affect the Comba AP2600-I WiFi Access Point.
These kinds of routers vulnerabilities are very serious. Routers are essentially the path to and from network and only one such defect can potentially affect each user and system on this network. A hacker-controlled router can block access to and from the network.
