A vulnerability, which was classified as critical, was found in Deskpro. This affects an unknown code block of the file /portal/api/style/edit-theme-set/template-sources of the component Helpdesk Interface. The manipulation of the argument code as part of a Parameter leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

An issue was discovered in Deskpro before 2019.8.0. This product enables administrators to modify the helpdesk interface by editing /portal/api/style/edit-theme-set/template-sources theme templates, and uses TWIG as its template engine. While direct access to self and _self variables was not permitted, one could abuse the accessible variables in one's context to reach a native unserialize function via the code parameter. There, on could pass a crafted payload to trigger a set of POP gadgets in order to achieve remote code execution.

The weakness was released 04/01/2020. This vulnerability is uniquely identified as CVE-2020-11467 since 04/01/2020. It is possible to initiate the attack remotely. The exploitation needs additional levels of successful authentication. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1059 for this issue.

Upgrading to version 2019.8.0 eliminates this vulnerability.
