<font 11pt/Calibri,sans-serif;;inherit;;inherit>Summary: Possible user impersonation in Stages when SAML authentication is enabled</font>

<font 11pt/Calibri,sans-serif;;inherit;;yellow>Release Date: XX</font>-10-2019

**__Severity:__** Medium (according to NVD definition; CVSS score: 4.6)

<font 11pt/Calibri,sans-serif;;inherit;;inherit>Affected Versions:</font>

  • <font 11pt/Calibri,sans-serif;;inherit;;inherit>7.3.0.0 to 7.3.5.0</font>
  • <font 11pt/Calibri,sans-serif;;inherit;;inherit>7.2.0.0 to 7.2.1.3</font>
  • <font 11pt/Calibri,sans-serif;;inherit;;inherit>6.7.4.2 to 6.7.8.0</font>

<font 11pt/Calibri,sans-serif;;inherit;;inherit>Previous minor and major versions, e.g. 7.1.x.y, 7.0.x.y, 6.6.x.y, 6.5.x.y, or 5.x.y.z are not affected.</font>

<font 11pt/Calibri,sans-serif;;inherit;;inherit>Only installations that have enabled SAML authentication are vulnerable.</font>

<font 11pt/Calibri,sans-serif;;inherit;;inherit>To find out which Stages version you are running, log in as “root” and click on the “Info” icon (6.x) or “Administration” menu (7.x).</font>

<font 11pt/Calibri,sans-serif;;inherit;;inherit>Description:</font>

<font 11pt/Calibri,sans-serif;;inherit;;inherit>During internal testing, we discovered a security vulnerability in the Stages login procedure that can result in users being able to impersonate another Stages user. Any Stages system accounts, e.g. “root” and “default” are not affected. Direct access to server resources cannot be gained. The vulnerability can only be exploited when SAML authentication is enabled on the server. If SAML authentication is not enabled, the system is not vulnerable.</font>

<font 11pt/Calibri,sans-serif;;inherit;;inherit>All vulnerable Stages Cloud instances have already been upgraded to versions that do not have the issue.</font>

<font 11pt/Calibri,sans-serif;;inherit;;inherit>As the vulnerability is only known within Method Park, active exploitation is very improbable. None of the systems analyzed by Method Park including all Stages Cloud instances showed any evidence of unauthorized usage. Please contact us for further information how to analyze if your system has been impacted.</font>

If you see indications of unauthorized usage, please contact security-alerts@methodpark.com immediately.

<font 11pt/Calibri,sans-serif;;inherit;;inherit>Fix:</font>

<font 11pt/Calibri,sans-serif;;inherit;;inherit>Upgrade your system to one of the following Stages versions:</font>
