Hi,
I am using Apache Commons IO v2.4 (commons-io-2.4.jar) in one of my projects. My organization uses Veracode to scan the deliveries of my project. Veracode scans the projects for vulnerability issues and flags the flaws if the code and/or third-party libraries used in the project are vulnerable for some external attacks. During the recent scan the Veracode system flagged an issue in commons-io-2.4.jar. Below are the details: *CWE ID:* 78 http://cwe.mitre.org/data/definitions/78.html *Name:* Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') *Module:* commons-io-2.4.jar *Source:* FileSystemUtils.java: *Line#* 535 *Attack Vector: *java.lang.Runtime.exec *Description:* This call to java.lang.Runtime.exec() contains a command injection flaw. The argument to the function is constructed using user-supplied input. If an attacker is allowed to specify all or part of the command, it may be possible to execute commands on the server with the privileges of the executing process. The level of exposure depends on the effectiveness of input validation routines, if any. The first argument to exec() contains tainted data from the variable cmdAttribs. The tainted data originated from earlier calls to java.lang.string.!operator_javanewinit, java.io.file.!operator_javanewinit, org.apache.commons.io.filesystemutils.freespacekb, org.apache.commons.io.filesystemutils.freespacekb, org.apache.commons.io.filenameutils.normalize, org.apache.commons.io.filenameutils.getprefixlength, and org.apache.commons.io.filesystemutils.freespace. *Remediation:* Validate all user-supplied input to ensure that it conforms to the expected format, using centralized data validation routines when possible. When using black lists, be sure that the sanitizing routine performs a sufficient number of iterations to remove all instances of disallowed characters. Most APIs that execute system commands also have a "safe" version of the method that takes an array of strings as input rather than a single string, which protects against some forms of command injection. Now, my organization needs an assessment report for the above issue from the author of the third-party library which in this case it is Apache. Can you please provide me the assessment report for above issue? Is this a known issue? And is it safe to use commons-io-2.4.jar keeping in mind the above issue? Thanks in advanced, Parag Joshi
