CVE-2023-1523
Last modified
CVE-2023-1523 is a critical-severity vulnerability rated 10/10 on the CVSS scale. Using the TIOCLINUX ioctl request, a malicious snap could inject contents into the input of the controlling terminal which could allow it to cause arbitrary commands to be executed outside of the snap sandbox after the snap exits. Graphical terminal emulators like xterm, gnome-terminal and others are not affected - this can only be exploited when snaps are run on a virtual console.. EPSS estimates a 1.45% chance of exploitation in the next 30 days.
