CVSS v3.1
Official Description
Digi ConnectPort X2e before 3.2.30.6 allows an attacker to escalate privileges from the python user to root via a symlink attack that uses chown, related to /etc/init.d/S50dropbear.sh and the /WEB/python/.ssh directory.
Technical Analysis
CVE-2020-12878 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.8.
