### DescriptionWebCTRL suffers from an authenticated arbitrary code execution vulnerability. The issue is caused due to the improper verification when uploading Add-on (.addons or .war) files using the uploadwarfile servlet. This can be exploited to execute arbitrary code by uploading a malicious web archive file that will run automatically and can be accessed from within the webroot directory. Additionaly, an improper authorization access control occurs when using the 'anonymous' user. By specification, the anonymous user should not have permissions or authorization to upload or install add-ons. In this case, when using the anonymous user, an attacker is still able to upload a malicious file via insecure direct object reference and execute arbitrary code. The anonymous user was removed from version 6.5 of WebCTRL.### VendorAutomated Logic Corporation – http://www.automatedlogic.com### Affected Version* ALC WebCTRL, i-Vu, SiteScan Web 6.5 and prior* ALC WebCTRL, SiteScan Web 6.1 and prior* ALC WebCTRL, i-Vu 6.0 and prior* ALC WebCTRL, i-Vu, SiteScan Web 5.5 and prior* ALC WebCTRL, i-Vu, SiteScan Web 5.2 and prior* Note: Current supported versions are 6.5, 6.1 and 6.0### Tested OnMicrosoft Windows 7 Professional (6.1.7601 Service Pack 1 Build 7601)Apache-Coyote/1.1Apache Tomcat/7.0.42CJServer/1.1Java/1.7.0_25-b17Java HotSpot Server VM 23.25-b01Ant 1.7.0Axis 1.4Trove 2.0.2Xalan Java 2.4.1Xerces-J 2.6.1### Vendor Status* [30.01.2017] Vulnerability discovered.* [27.03.2017] Vendor contacted.* [13.04.2017] No response from the vendor.* [14.04.2017] ICS-CERT contacted.* [17.04.2017] ICS-CERT asks details to coordinate with the vendor.* [20.04.2017] Sent details to ICS-CERT.* [21.04.2017] ICS-CERT assigned ticket ID: ICS-VU-696479 to this issue.* [19.05.2017] ICS-CERT informs that the vendor has validated the issues and begun working on patch.* [07.06.2017] Asked ICS-CERT for status update.* [26.06.2017] ICS-CERT responded with vendor info: Vendor has created patch for 6.5 and currently working on patch for 6.1 and 6.0.
