**Release Date:** May 31, 2016

**Component Type:** Third party extension. This extension is not a part of the TYPO3 default installation.

**Affected Versions:** version 2.5.8 and below

**Vulnerability Type:** Information Disclosure

**Severity:** Medium

**Suggested CVSS v2.0:** [AV:N/AC:L/Au:N/C:P/I:N/A:N/E:W/RL:W/RC:C](http://jvnrss.ise.chuo-u.ac.jp/jtg/cvss/cvss2.cgi?vector=%28AV:N/AC:L/Au:N/C:P/I:N/A:N/E:W/RL:W/RC:C%29&g=2&lang=en "CVSS calculator") ([What's that?](http://buzz.typo3.org/teams/security/article/use-of-common-vulnerability-scoring-system-in-typo3-security-advisories/ "Blog post on CVSS usage"))

**CVE:** CVE-2014-3758

**Problem Description:** Files containing the answered questionnaires are stored in the "typo3temp" directory within the TYPO3 installation. As the extension uses predictable names for the questionnaire answer forms it is easy to guess file names and download answer files.

**Solution:** An updated version 3.0.14 is available from the TYPO3 Extension Manager and at [https://typo3.org/extensions/repository/download/ke\_questionnaire/3.0.14/t3x/](https://typo3.org/extensions/repository/download/ke_questionnaire/3.0.14/t3x/ "Opens external link in new window"). Users of the extension are advised to update the extension as soon as possible.

**Credits**: Credits go to Patrick Hof and Henri Salo who reported the vulnerability.

**General advice:** Follow the recommendations that are given in the [TYPO3 Security Guide](http://docs.typo3.org/typo3cms/SecurityGuide/ "Initiates file download"). Please subscribe to the [typo3-announce mailing list](http://lists.typo3.org/cgi-bin/mailman/listinfo/typo3-announce "Opens external link in new window") to receive future Security Bulletins via E-mail.
