**Release Date:** May 30, 2012

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

**Affected Versions:** Version 1.6.6 and below

**Vulnerability Type:** Cross-site scripting

**Severity:** Medium

**Suggested CVSS v2.0:** [AV:N/AC:M/Au:S/C:P/I:N/A:N/E:U/RL:O/RC:C](http://jvnrss.ise.chuo-u.ac.jp/jtg/cvss/cvss2.cgi?vector=(AV:N/AC:M/Au:S/C:P/I:N/A:N/E:U/RL:O/RC:C)&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:** Failing to properly sanitize user-supplied input the extension is open to Cross-Site Scripting attacks. Exploiting this flaw requires access to the scheduler module.

**Solution:** An updated version 1.6.7 is available from the TYPO3 extension manager and at [http://typo3.org/extensions/repository/view/powermail/1.6.7/](http://typo3.org/extensions/repository/view/powermail/1.6.7/ "Opens external link in new window"). Users of the extension are advised to update the extension as soon as possible.

**Credits:** Credits go to TYPO3 Security Team member Georg Ringer who discovered the issue.

**General advice:** Follow the recommendations that are given in the [TYPO3 Security Guide](http://typo3.org/documentation/document-library/extension-manuals/doc_guide_security/current/ "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.
