Name of the Vulnerable Software and Affected Versions Allegra (affected versions not specified)

Description This issue allows remote attackers to execute arbitrary code on affected installations of Allegra. Although authentication is required to exploit this issue, the product implements a registration mechanism that can be used to create a user with a sufficient privilege level. The specific flaw exists within the renderFieldMatch method, resulting from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this issue to execute code in the context of LOCAL SERVICE.

Recommendations At the moment, there is no information about a newer version that contains a fix for this issue.
