Apache Tomcat unexpected file deletion and/or alteration
http://www.securityfocus.com/archive/1/archive/1/509148/100/0/threaded<!--正文--><!--判断阅读权限--><!--判断是否已经扣点-->Severity: Low
Vendor:
The Apache Software Foundation
Versions Affected:
Tomcat 5.5.0 to 5.5.28
Tomcat 6.0.0 to 6.0.20
The unsupported Tomcat 3.x, 4.x and 5.0.x versions may be also
affected.
Description:
When deploying WAR files, the WAR files were not checked for directory
traversal attempts. This allows an attacker to create arbitrary content
outside of the web root.
Mitigation:
6.0.x users should upgrade to 6.0.24 or apply this patch:
http://svn.apache.org/viewvc?rev=892815&view=rev
5.5.x users should upgrade to 5.5.29 when released or apply this patch:
http://svn.apache.org/viewvc?rev=902650&view=rev
Note: the patches also address CVE-2009-2901 and CVE-2009-2902.
Alternatively, users of all Tomcat versions may mitigate this issue by
manually validating the contents of untrusted WAR files before deployment.
Example:
A WAR file that contains the following entry will overwrite the standard
Windows start-up script when deployed on a default Tomcat installation:
../../bin/catalina.bat
