CVE-2020-28008
Last modified
CVE-2020-28008 is a high-severity vulnerability rated 7.8/10 on the CVSS scale. Exim 4 before 4.94.2 allows Execution with Unnecessary Privileges. Because Exim operates as root in the spool directory (owned by a non-root user), an attacker can write to a /var/spool/exim4/input spool header file, in which a crafted recipient address can indirectly lead to command execution.. EPSS estimates a 0.41% chance of exploitation in the next 30 days.
