Software vulnerabilities leave home routers hackable

ESET’s Home Network Protection feature scans home routers for vulnerabilities and weak passwords

ESET has revealed that its latest security offering has uncovered software vulnerabilities in home routers due to weak password choices.

In April this year, ESET introduced its Home Network Protection feature that enables users to scan their home routers for vulnerabilities, malicious configurations, exploitable network services and weak passwords. Its analysis found that almost 7% of the routers tested demonstrated software vulnerabilities of high or medium severity. Furthermore, port scanning revealed that network services were accessible from internal as well as from external networks.

In addition, the results also prove that 15% of the routers tested used weak passwords, with “admin” left as the username in most cases.

Peter Stančík, ESET security evangelist, said: “In particular, unsecured services such as Telnet shouldn’t be left open, not even to local network, which was – unfortunately – the case with more than 20% of the routers tested.

“During the test, we tried common default usernames and passwords and also some frequently used combinations. It’s disturbing that more than one in seven of such simple simulated attacks was successful.”

Another frequent vulnerability discovered was a command injection vulnerability, this aims for the execution of arbitrary commands on the host operating system via a vulnerable application, largely with insufficient input validation.

“The results collected by ESET Home Network Protection during BETA testing of ESET security solutions clearly show that routers can be attacked fairly easily, by exploiting one of the frequently found vulnerabilities. This makes them an Achilles heel for the overall internet security of households as well as small businesses,” added Stančík.
