AI-Generated

Apache Struts is vulnerable to an Expression Language Injection flaw that could allow remote code execution if the legacy RESTful action mapper is used and the OGNL allowlist is disabled. This affects versions from 2.0.0 through 7.3.0, and organizations utilizing these versions should prioritize upgrading to 6.12.0 or 7.4.0 to mitigate the risk. Users of the default action mapper, restful2 mapper, or Struts REST plugin are not impacted and do not need to take immediate action.

Original NVD Description

Improper neutralization of special elements used in an expression language statement ('Expression Language Injection') vulnerability in Apache Struts. If the application is configured to use the legacy RESTful action mapper, a crafted request can inject an OGNL expression that may lead to remote code execution. Struts 7 is affected only when the OGNL allowlist is disabled; it is enabled by default. Applications using the default action mapper, the restful2 mapper, or the Struts REST plugin are not affected. This issue affects Apache Struts: from 2.0.0 through 2.3.37, from 2.5.0 through 2.5.33, from 6.0.0 through 6.11.0, from 7.0.0 through 7.3.0. Users are recommended to upgrade to version 6.12.0 or 7.4.0, which fixes the issue.
