CVE-2024-30372

Estado: AnalizadaMedia (6.3)—

Allegra getLinkText Server-Side Template Injection Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Allegra. Authentication is required to exploit this vulnerability.

The specific flaw exists within the implementation of getLinkText method. The issue results from the lack of proper validation of a user-supplied string before processing it with the template engine. An attacker can leverage this vulnerability to execute code in the context of LOCAL SERVICE. Was ZDI-CAN-23609.
