Project: E-Sign [1]
Version: 7.x-1.9
Date: 2018-December-19
Security risk: *Moderately critical* 14∕25
AC:Basic/A:User/CI:Some/II:Some/E:Theoretical/TD:All [2]
Vulnerability: Cross site scripting

Description: 
This module allows for integration of Signature Pad, an electronic-signing
script, into Drupal for both nodes (content), the Field API (FAPI), and
Webforms.

The module doesn't sufficiently filter user input when displaying a
signature.

The vulnerability is mitigated by the fact that an attacker must have the
ability to submit a signature. That permission might be associated with
submitting a webform or creating or editing a node depending on site
configuration.

Solution: 
Install the latest version:

  * If you use the Esign module for Drupal 7.x, upgrade to Esign 7.x-1.10 [3]

Also see the E-Sign [4] project page.
