Amazon Linux 2 : apache-commons-io (ALAS-2023-2059)

medium Nessus Plugin ID 176708


The remote Amazon Linux 2 host is missing a security update.


The version of apache-commons-io installed on the remote host is prior to 2.4-12. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2059 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.


Run 'yum update apache-commons-io' to update your system.
