CVE-2023-51641 is a medium-severity vulnerability rated 6.3/10 on the CVSS scale. Allegra renderFieldMatch Deserialization of Unstrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Allegra. EPSS estimates a 1.26% chance of exploitation in the next 30 days.

Description

Allegra renderFieldMatch Deserialization of Unstrusted Data Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of Allegra. Although authentication is required to exploit this vulnerability, 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. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of LOCAL SERVICE. Was ZDI-CAN-22505.
