Security Advisory Recommended Actions If you are running a version listed in the Versions known to be vulnerable column, you can eliminate this vulnerability by upgrading to a version listed in the Fixes introduced in column. If the table lists only an older version than what you are currently running, or does not list a non-vulnerable version, then no upgrade candidate currently exists. Mitigation To mitigate this vulnerability, you can create an iRule and apply it to the affected virtual server. To do so, perform the following procedure: Impact of action: Performing the following procedure should not have a negative impact on your system. 1. Log in to the Configuration utility. 2. Navigate to Local Traffic > iRules. 3. Click Create. 4. In the Name box, enter a name for the iRule. 5. In the Definition box, enter the following code: when CLIENT_ACCEPTED { ACCESS::restrict_irule_events disable } when HTTP_REQUEST { if {[HTTP::uri] starts_with "/vdesk/resource_info_v2.xml?" && [URI::decode [HTTP::query]] contains "<"} { HTTP::uri [HTTP::path] } } 6. Click Finished. 7. Navigate to Local Traffic > Virtual Servers. 8. In the Resources column, click Edit for the affected virtual server. 9. For iRules, click Manage. 10. For iRule, select the new iRule in the Available box and move it to the Enabled box. 11. Click Finished.
