**Release Date:** September 30, 2015

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

**Affected Versions:**  version 2.8.18 and below

**Vulnerability Type:** Information Disclosure

**Severity:** Low

**Suggested CVSS v2.0:** [AV:N/AC:L/Au:N/C:P/I:N/A:N/E:F/RL:U/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:F/RL:U/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"))

**Problem Description:** The extension turns on PHP error output. When the ldap service is enabled in configuration for backend or frontend, PHP errors can be shown during login process, which would disclose the full server path.

**Solution:** Versions of this extension that are known to be vulnerable will no longer be available for download from the TYPO3 Extension Repository. The extension author is no longer maintaining this extension. Please uninstall and delete the extension folder from your installation.

**Credits:** Credits go to security team member Nicole Cordes who discovered and reported the issue.

**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.
