Title : Apache Struts Multiple Security Bypass and Cross Site Scripting Vulnerabilities VUPEN ID : VUPEN/ADV-2006-1205 CVE ID : CVE-2006-1546 - CVE-2006-1547 - CVE-2006-1548
Rated as : Moderate Risk
Remotely Exploitable : Yes Locally Exploitable : Yes Release Date : 2006-04-03
Technical Description
Multiple vulnerabilities have been identified in Apache Struts, which may be exploited by attackers to bypass security restrictions, execute arbitrary scripting code, or cause a denial of service.
The first issue is due to an error when handling a request with a "org.apache.struts.taglib.html.Constants.CANCEL" parameter, which could be exploited by attackers to cause the action to be canceled without being detected from applications that do not use the "isCancelled" check.
The second flaw is due to an error in BeanUtils that does not properly handle a "multipart/form-data" encoded form with a parameter name that references the public "getMultipartRequestHandler()" method, which could be exploited by attackers to cause a denial of service or gain access to elements in the "CommonsMultipartRequestHandler" implementation and BeanUtils.
The third vulnerability is due to input validation errors in "LookupDispatchAction" when handling a parameter name that does not correspond to an entry in the "lookupMap", which could be exploited by attackers to cause arbitrary scripting code to be executed by the user's browser in the security context of an affected Web site.
