The <a href=\"https:\/\/support.citrix.com\/article\/CTX267027\">vulnerability<\/a> was assigned the following CVE number:<\/p>\n<ul>\n<li><a href=\"https:\/\/support.citrix.com\/article\/CTX267027\">CVE-2019-19781<\/a> : Vulnerability in Citrix Application Delivery Controller and Citrix Gateway leading to arbitrary code execution<\/li>\n<\/ul>\n<p>The vulnerability affects all product versions and all platforms:<\/p>\n<ul>\n<li>Citrix ADC and Citrix Gateway version 13.0 all supported builds<\/li>\n<li>Citrix ADC and NetScaler Gateway version 12.1 all supported builds<\/li>\n<li>Citrix ADC and NetScaler Gateway version 12.0 all supported builds<\/li>\n<li>Citrix ADC and NetScaler Gateway version 11.1 all supported builds<\/li>\n<li>Citrix NetScaler ADC and NetScaler Gateway version 10.5 all supported builds<\/li>\n<\/ul>\n<p>Numerous working exploits have already been developed and have made publicly available in numerous locations. The vulnerability allows an attacker to gain full control of the device.<\/p>\n<p>There is no patch currently available for this vulnerability, though Citrix has stated that they are currently being developed. They listed the following timelines:<\/p>\n<table style=\"height: 265px;\" width=\"635\">\n<tbody>\n<tr>\n<td><strong>Version<\/strong><\/td>\n<td><strong>Refresh Build<\/strong><\/td>\n<td><strong>Expected Release Date<\/strong><\/td>\n<\/tr>\n<tr>\n<td>10.5<\/td>\n<td>10.5.70.x<\/td>\n<td>31st January 2020<\/td>\n<\/tr>\n<tr>\n<td>11.1<\/td>\n<td>11.1.63.x<\/td>\n<td>20th January 2020<\/td>\n<\/tr>\n<tr>\n<td>12.0<\/td>\n<td>12.0.63.x<\/td>\n<td>20th January 2020<\/td>\n<\/tr>\n<tr>\n<td>12.1<\/td>\n<td>12.1.55.x<\/td>\n<td>27th\u00a0January 2020<\/td>\n<\/tr>\n<tr>\n<td>13.0<\/td>\n<td>13.0.47.x<\/td>\n<td>27th\u00a0January 2020<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>In the interim Citrix has provided mitigations, until the permanent fix is available. The fixes can be found here: <a href=\"https:\/\/support.citrix.com\/article\/CTX267679\">https:\/\/support.citrix.com\/article\/CTX267679<\/a>. IDS systems should also be configured to monitor for this threat. You can test if the mitigations have been applied properly by running the following command:<\/p>\n<h5>[highlight background_color=&#8221;#e3f35e&#8221; color=&#8221;#666&#8243;]<strong>curl https:\/\/&lt;Your Server IP or hostname&gt;\/vpn\/..\/vpns\/cfg\/smb.conf &#8211;path-as-is<\/strong>[\/highlight]<\/h5>\n<p>If you receive a 403 response, it means you properly applied the fix. If you can see the smb.conf, the fix was not applied correctly, and the device is still vulnerable.<\/p>\n<p>Don&#8217;t wait, make sure to patch all of your devices now.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>On December 17, 2019, Citrix published an article describing vulnerability\u00a0affecting the Citrix Application Delivery Controller (ADC) and Citrix Gateway formerly known as NetScaler ADC and Gateway.
