The MultiPageValidator implementation in Apache Struts 1 1.1 through 1.3.10 allows remote attackers to bypass intended access restrictions via a modified page parameter.

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-031330 advisory.

    The MultiPageValidator implementation in Apache Struts 1 1.1 through 1.3.10 allows remote attackers to     bypass intended access restrictions via a modified page parameter.

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

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

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - The MultiPageValidator implementation in Apache Struts 1 1.1 through 1.3.10 allows remote attackers to     bypass intended access restrictions via a modified page parameter. (CVE-2015-0899)

Note that Nessus relies on the presence of the package as reported by the vendor.

The IBM WebSphere Application Server running on the remote host is version 7.0.0.x through 7.0.0.45, 8.0.0.x through 8.0.0.15, 8.5.0.x prior to 8.5.5.14, or 9.x prior to 9.0.0.8. It is, therefore, affected by a vulnerability in the Apache Struts subcomponent deu to an error in the MultiPageValidator implementation. An unauthenticated, remote attacker can exploit this, using a modified page parameter, to bypass restrictions and launch further attacks on the system.

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

It was discovered that libstruts1.2-java, a Java framework for MVC applications, contains a bug in its multi-page validation code. This allows input validation to be bypassed, even if MPV is not used directly.
