Command Execution Vulnerability in Apache SpamAssassin by The Apache Software Foundation

CVE-2020-1930

What is CVE-2020-1930?

A command execution vulnerability has been identified in Apache SpamAssassin versions prior to 3.4.3, allowing an attacker to exploit carefully crafted rule configuration files (.cf). These malicious configurations can trigger system commands to run with the same privileges as the spamd process, posing a significant risk, particularly if the spamd is run with elevated privileges. To mitigate the risk, upgrading to version 3.4.4 is essential. Additionally, users are advised to limit the use of third-party .cf files to trusted sources and to avoid using sa-compile or operating spamd with heightened privileges if an upgrade is not possible.
