Description:
Secunia Research has discovered a vulnerability in IMP Webmail Client and Horde Groupware Webmail Edition, which can be exploited by malicious people to bypass certain security restrictions and manipulate data.
The HTML filter does not filter out <frame> and <frameset> HTML elements. Additionally, the application allows users to perform certain actions via HTTP requests without performing any validity checks to verify the request. This can be exploited to (a) delete an arbitrary number of e-mail messages by referencing their numeric IDs and (b) purge deleted mails, when the victim opens a malicious HTML mail.
Successful exploitation requires that the victim opens the HTML part of a malicious message.
The vulnerability is confirmed in IMP version 4.1.5 with Horde version 3.1.5 and also reported in Horde Groupware Webmail Edition 1.0.3. Other versions may also be affected.
Solution:
Update to Horde version 3.1.6 or Horde Groupware Webmail Edition 1.0.4.
