Code injection in Apache Struts

A vulnerability introduced by forcing parameter inclusion in the URL and Anchor Tag allows remote command execution, session access and manipulation and XSS attacks. both the s:url and s:a tag provide an includeParams attribute. The main scope of that attribute is to understand whether includes...

GHSA-X5FC-PGPX-59J5 Server side object manipulation in Apache Struts

OGNL provides, among other features, extensive expression evaluation capabilities. This vulnerability allows a malicious user to bypass the ''-usage protection built into the ParametersInterceptor, thus being able to manipulate server side context objects. This behavior was already addressed in...

Code injection in Apache Struts

The Struts 2 DefaultActionMapper supports a method for short-circuit navigation state changes by prefixing parameters with "action:" or "redirect:", followed by a desired navigational target expression. This mechanism was intended to help with attaching navigational information to buttons within...

VulnCheck KEV: CVE-2021-31805

The fix issued for CVE-2020-17530 was incomplete. So from Apache Struts 2.0.0 to 2.5.29, still some of the tag’s attributes could perform a double evaluation if a developer applied forced OGNL evaluation by using the %... syntax. Using forced OGNL evaluation on untrusted user input can lead to a...

GHSA-4WRR-9H5R-M92W Apache Struts Remote Java Code Execution

The ExceptionDelegator component in Apache Struts before 2.2.3.1 interprets parameter values as OGNL expressions during certain exception handling for mismatched data types of properties, which allows remote attackers to execute arbitrary Java code via a crafted parameter...

Struts ParameterInterceptor vulnerability allows remote command execution

Regular expression in ParametersInterceptor matches top'foo' as a valid expression, which OGNL treats as top'foo'0 and evaluates the value of 'foo' action parameter as an OGNL expression. This lets malicious users put arbitrary OGNL statements into any String variable exposed by an action and hav...

Apache Struts Remote Code Execution Vulnerability (CNVD-2023-02478)

A remote code execution vulnerability exists in Apache Struts, an open source web application architecture for developing Java EE web applications from the Apache Foundation, which stems from the use of mandatory OGNL evaluation in tag attributes for untrusted user input. An attacker could exploi...
