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.
ActionServlet.java in Apache Struts 1 1.x through 1.3.10 does not properly restrict the Validator configuration, which allows remote attackers to conduct cross-site scripting (XSS) attacks or cause a denial of service via crafted input, a related issue to CVE-2015-0899.
ActionServlet.java in Apache Struts 1 1.x through 1.3.10 mishandles multithreaded access to an ActionForm instance, which allows remote attackers to execute arbitrary code or cause a denial of service (unexpected memory access) via a multipart request, a related issue to CVE-2015-0899.
Cross-site scripting (XSS) vulnerability in (1) LookupDispatchAction and possibly (2) DispatchAction and (3) ActionDispatcher in Apache Software Foundation (ASF) Struts before 1.2.9 allows remote attackers to inject arbitrary web script or HTML via the parameter name, which is not filtered in the resulting error message.
Cross-site scripting (XSS) vulnerability in Apache Struts before 1.2.9-162.31.1 on SUSE Linux Enterprise (SLE) 11, before 1.2.9-108.2 on SUSE openSUSE 10.3, before 1.2.9-198.2 on SUSE openSUSE 11.0, and before 1.2.9-162.163.2 on SUSE openSUSE 11.1 allows remote attackers to inject arbitrary web script or HTML via unspecified vectors related to "insufficient quoting of parameters."
ActionForm in Apache Software Foundation (ASF) Struts before 1.2.9 with BeanUtils 1.7 allows remote attackers to cause a denial of service via a multipart/form-data encoded form with a parameter name that references the public getMultipartRequestHandler method, which provides further access to elements in the CommonsMultipartRequestHandler implementation and BeanUtils.
Apache Software Foundation (ASF) Struts before 1.2.9 allows remote attackers to bypass validation via a request with a 'org.apache.struts.taglib.html.Constants.CANCEL' parameter, which causes the action to be canceled but would not be detected from applications that do not use the isCancelled check.
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 Remote Code Execution and security degradation.
