In Apache SpamAssassin before 3.4.3, nefarious CF files can be configured to run system commands without any output or errors. With this, exploits can be injected in a number of scenarios. In addition to upgrading to SA 3.4.3, we recommend that users should only use update channels or 3rd party .cf files from trusted places.

The remote Redhat Enterprise Linux 7 host has one or more packages installed that are affected by multiple vulnerabilities that have been acknowledged by the vendor but will not be patched.

  - spamassassin: Malicious rule configuration files can be configured to run system commands (CVE-2020-1946)

  - In Apache SpamAssassin before 3.4.3, nefarious CF files can be configured to run system commands without     any output or errors. With this, exploits can be injected in a number of scenarios. In addition to     upgrading to SA 3.4.3, we recommend that users should only use update channels or 3rd party .cf files from     trusted places. (CVE-2018-11805)

  - A command execution issue was found in Apache SpamAssassin prior to 3.4.3. Carefully crafted nefarious     rule configuration (.cf) files can be configured to run system commands similar to CVE-2018-11805. With     this bug unpatched, exploits can be injected in a number of scenarios including the same privileges as     spamd is run which may be elevated 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. If you cannot upgrade, do not use 3rd party rulesets, do not use sa-compile and do not run spamd     as an account with elevated privileges. (CVE-2020-1930)

Note that Nessus has not tested for these issues but has instead relied on the package manager's report that the package is installed.

According to the versions of the spamassassin package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

In addition to upgrading to     SA 3.4.3, we recommend that users should only use     update channels or 3rd party .cf files from trusted     places.(CVE-2018-11805)

  - In Apache SpamAssassin before 3.4.5, malicious rule     configuration (.cf) files can be configured to run     system commands without any output or errors. With     this, exploits can be injected in a number of     scenarios. In addition to upgrading to SA version     3.4.5, users should only use update channels or 3rd     party .cf files from trusted places.(CVE-2020-1946)
