Security Vulnerability in Geocortex Viewer for HTML5
If you use Geocortex Viewer for HTML5, update your apps!
From Drew Millen, Geocortex Product Manager at Latitude Geographics Group:
Yesterday we were made aware of a potential security issue affecting all versions of Geocortex Viewer for HTML5, thanks to a vigilant customer contacting our Support team. While we don’t know of any specific attacks that may have exploited this vulnerability amongst our customers, we take potential security issues very seriously. We’re happy to report that we were able to respond quickly, and a patch will be available for download in the Geocortex Support Center in the coming hours. The patch involves replacing a single JavaScript file and does not require a re-install or that you update Geocortex Essentials. We recommend customers with applications that use Geocortex Viewer for HTML5 (all versions) apply the patch. Note that the upcoming release of Geocortex Viewer for HTML5 2.4 will not expose this vulnerability. Here’s what you need to know:
- This issue potentially allows a malicious attacker to craft a viewer URL that loads configuration and code from a domain under their control.
- This issue is a result of the way viewer configurations have historically been loaded. In the past, attempts to load configurations from other domains were prevented by the browser; however, newer browsers have evolved to support a technology called Cross-Origin Resource Sharing (CORS), which now allows cross-domain requests to be made.
- An attacker can craft a link to a viewer on a trusted domain, such as http: //trusted/viewer/index.html, that loads their malicious configuration file from a machine that they control. If the attacker’s server is configured correctly, they can serve malicious code to users who have been fooled into clicking the link.
- An example of a malicious link could be: http: //trusted/viewer/index.html?configBase=http://go.geocortex.com/e/61102/2015-03-26/3qh36/47536401resources/config/default/
- All browsers supporting CORS — including ones in iOS and Android — are susceptible.
Here’s what we recommend you do:
- Download the applicable patches we are making available in the Geocortex Support Center. Click the “Geocortex Viewer for HTML5” link and look for Security Update 2015-03-26.zip.
- Read instructions.txt for notes regarding potential changes to viewer launch links in certain advanced scenarios.
- Follow instructions.txt for instructions on applying the patch.
We apologize for any inconvenience this issue may cause you. Please get in touch with us if you have any questions or if we can help.

GeoTech PCC is a new program that just started this semester. We’re fortunate to have Jonathan Robinson and Chandler Sterling from the City of Pasadena give our first guest lectures. We want to make sure that those in the surrounding communities know about it!
Google Search Cost Map
Check out this map showing the autocomplete predictions of a “cost search” for each state’s capital. The search phase was “how much does a * cost in …”. Some of the autocomplete predictions were rather … well, you will see!
First Proposed US Highway Network Map
Back in 1913, the National Highway Association drew up the first proposed highway plan. Their campaign stressed that good roads lead to things like good schools, good health, good morals, good times, etc. Check out the article and maps leading up to the nation’s first nationwide system of numbered highways adopted in November 1926.
California Has One Year of Water Left
According to Jay Famiglietti, the senior water scientist at the NASA Jet Propulsion Laboratory/Caltech and a professor of Earth system science at UC Irvine, California has about one year of water supply left in its reservoirs. Are you ready to ration? What is your government agency you work for going to do? Imagine what this will do to California’s economy … and the way we will live here, or leave for greener pastures. Check out the LA Times Op-Ed piece.

Check out this story about how a previously unknown map collection of a hospital dietician ended up doubling the size of the Los Angeles Public Library’s map archives in one single day!
Mapping Migration in the US
This interesting and interactive map comes from the New York Times. A lot of information is displayed showing migration information by state. Very good use of colors and symbols to show multi layered migration data. Select a year, then hover over the different areas of the state to get more info. Check it out.
Make a Wind Map
Curious on how to make a wind map? Or maybe just a map of magnitude and direction of flow? I found this post that steps you through the process using ArcGIS Desktop.
Map History Directory
Interested in map history? Doing a research projected in map history or cartography? You might want to check out The International Directory of Researchers in Map History.
The purpose of the directory is to promote communication among researchers who study the history of maps and to provide information about the field to the public. The directory is an open source for contact information, current interests, research projects, and publications related to map history. Check it out.
