Ubuntu 20.04 LTS / 22.04 LTS : Apache Tika vulnerability (USN-8717-1)

medium Nessus Plugin ID 344615

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 20.04 LTS / 22.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-8717-1 advisory.

 It was discovered that Apache Tika's ISA-Tab parser incorrectly handled file path resolution. An attacker who could place files in a directory that Tika subsequently parses could use this issue to read arbitrary files

 accessible to the Tika process and have their contents emitted into the

 extracted text output.

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

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 libtika-java package.
