According to the version of the velocity package installed, the EulerOS installation on the remote host is affected by the following vulnerability :

  - An attacker that is able to modify Velocity templates     may execute arbitrary Java code or run arbitrary system     commands with the same privileges as the account     running the Servlet container. This applies to     applications that allow untrusted users to     upload/modify velocity templates running Apache     Velocity Engine versions up to 2.2.(CVE-2020-13936)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The version of velocity installed on the remote host is prior to 1.7-10.2. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2021-1690 advisory.

This update for velocity fixes the following issues :

  - CVE-2020-13936: Fixed an arbitrary code execution when     attacker is able to modify templates (bsc#1183360).

This update was imported from the SUSE:SLE-15-SP2:Update update project.

It was discovered that there was a potential arbitrary code execution vulnerability in velocity, a Java-based template engine for writing web applications. It could be exploited by applications which allowed untrusted users to upload/modify templates.

For Debian 9 'Stretch', this problem has been fixed in version 1.7-5+deb9u1.

We recommend that you upgrade your velocity packages.
