CVE-2018-25235

MEDIUM 6.9EPSS 0.22%

Does this matter?

Lower severity and a low EPSS score (0.22%). Track it; it rarely justifies an emergency change on its own.

Description

NetworkActiv Web Server 4.0 contains a buffer overflow vulnerability in the username field of the Security options that allows local attackers to crash the application by supplying an excessively long string. Attackers can trigger a denial of service by entering a crafted username value exceeding the expected buffer size through the Set username interface.
