Several vulnerabilities have been discovered in the otrs2 package that may lead to unauthorized access, remote code execution and spoofing.

CVE-2020-1765

An improper control of parameters allows the spoofing of the from fields of the following screens: AgentTicketCompose, AgentTicketForward, AgentTicketBounce.

CVE-2020-1766

Due to improper handling of uploaded images it is possible in very unlikely and rare conditions to force the agents browser to execute malicious JavaScript from a special crafted SVG file rendered as inline jpg file.

CVE-2020-1767

The remote Debian 10 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-3551 advisory.

  - jQuery before 3.4.0, as used in Drupal, Backdrop CMS, and other products, mishandles jQuery.extend(true,     {}, ...) because of Object.prototype pollution. If an unsanitized source object contained an enumerable
    __proto__ property, it could extend the native Object.prototype. (CVE-2019-11358)
