>> Apache Tomcat Multiple Cross Site Scripting and Security Bypass Vulnerabilities
|
Multiple vulnerabilities have been identified in Apache Tomcat, which could be exploited by attackers to bypass security restrictions or execute arbitrary scripting code.
The first vulnerability is caused by input validation errors in the calendar application included as part of the JSP examples, 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.
The second issue is caused by an error in the default SSL configuration that permits the use of insecure cipher suites including the anonymous cipher suite, which could be exploited to bypass security restrictions.
The third vulnerability is caused by an input validation error when processing and displaying certain "Accept-Language" headers, 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.
The fourth issue is caused by input validation errors in the "implicit-objects.jsp" file (included with the examples webapp) when processing certain header values, 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.
