Last modified Jun 16, 2026

CVE-2010-3843 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. The GTK version of ettercap uses a global settings file at /tmp/.ettercap_gtk and does not verify ownership of this file. When parsing this file for settings in gtkui_conf_read() (src/interfacesgtk/ec_gtk_conf.c), an unchecked sscanf() call allows a maliciously placed settings file to overflow a statically-sized buffer on the stack.. EPSS estimates a 0.31% chance of exploitation in the next 30 days.
