Ubuntu 18.04 LTS / 20.04 LTS : Apache Commons IO vulnerability (USN-5095-1)

medium Nessus Plugin ID 153788

Synopsis

The remote Ubuntu host is missing a security update.

Description

The remote Ubuntu 18.04 LTS / 20.04 LTS host has a package installed that is affected by a vulnerability as referenced in the USN-5095-1 advisory.

- In Apache Commons IO before 2.7, When invoking the method FileNameUtils.normalize with an improper input string, like //../foo, or \\..\foo, the result would be the same value, thus possibly providing access to files in the parent directory, but not further above (thus limited path traversal), if the calling code would use the result to construct a path value. (CVE-2021-29425)

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 libcommons-io-java package.
