Last modified
CVE-2019-19920 is a high-severity vulnerability rated 8.8/10 on the CVSS scale. sa-exim 4.2.1 allows attackers to execute arbitrary code if they can write a .cf file or a rule. This occurs because Greylisting.pm relies on eval (rather than direct parsing and/or use of the taint feature). EPSS estimates a 3.16% chance of exploitation in the next 30 days.
