Description
This vulnerability allows remote attackers to execute arbitrary code on affected installations of OpenText Brava! Desktop 16.6.3.84. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the processing of DWG files. The issue results from the lack of validating the existence of an object prior to performing operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-13311.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
A use-after-free vulnerability in OpenText Brava! Desktop 16.6.3.84 allows remote code execution via a crafted DWG file when opened by a user.
Vulnerability
The vulnerability is a use-after-free in OpenText Brava! Desktop version 16.6.3.84 during the processing of DWG files. The flaw arises because the software does not validate the existence of an object before performing operations on it, leading to a use-after-free condition. This affects the DWG parsing component. [1]
Exploitation
Exploitation requires user interaction: the target must open a malicious DWG file or visit a malicious page that triggers the parsing. No authentication or special network position is needed; the attacker can deliver the file via email, web download, or other means. Once the file is processed, the use-after-free is triggered. [1]
Impact
Successful exploitation allows an attacker to execute arbitrary code in the context of the current process. This could lead to full compromise of the application and potentially the underlying system, depending on the privileges of the user running Brava! Desktop. [1]
