A vulnerability classified as critical has been found in Apache SpamAssassin up to 3.4.2 (Anti-Spam Software). Affected is an unknown function. The manipulation as part of a System Command leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

A command execution issue was found in Apache SpamAssassin prior to 3.4.3. Carefully crafted nefarious Configuration (.cf) files can be configured to run system commands similar to CVE-2018-11805. This issue is less stealthy and attempts to exploit the issue will throw warnings. Thanks to Damian Lukowski at credativ for reporting the issue ethically. With this bug unpatched, exploits can be injected in a number of scenarios though doing so remotely is difficult. In addition to upgrading to SA 3.4.4, we again recommend that users should only use update channels or 3rd party .cf files from trusted places.

The weakness was disclosed 01/30/2020 (Website). The advisory is available at bz.apache.org. This vulnerability is traded as CVE-2020-1931 since 12/02/2019. It is possible to launch the attack remotely. The exploitation doesn't require any form of authentication. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1202 by the MITRE ATT&CK project.

Upgrading to version 3.4.3 eliminates this vulnerability.
