CBL Mariner 2.0 Security Update: javapackages-bootstrap / maven (CVE-2021-26291)

critical Nessus Plugin ID 236815

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of javapackages-bootstrap / maven installed on the remote CBL Mariner 2.0 host is prior to tested version.
It is, therefore, affected by a vulnerability as referenced in the CVE-2021-26291 advisory.

 - Apache Maven will follow repositories that are defined in a dependency's Project Object Model (pom) which May be surprising to some users, resulting in potential risk if a malicious actor takes over that repository or is able to insert themselves into a position to pretend to be that repository. Maven is changing the default behavior in 3.8.1+ to no longer follow http (non-SSL) repository references by default. More details available in the referenced urls. If you are currently using a repository manager to govern the repositories used by your builds, you are unaffected by the risks present in the legacy behavior, and are unaffected by this vulnerability and change to default behavior. See this link for more information about repository management: https://maven.apache.org/repository-management.html (CVE-2021-26291)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
