CVE-2021-46631
Description
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Bentley View 10.15.0.75. 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 parsing of TIF images. The issue results from the lack of proper initialization of memory prior to accessing it. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-15461.
AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
A use-of-uninitialized-memory vulnerability in Bentley View's TIF parsing allows remote code execution via a malicious file.
Vulnerability
The vulnerability exists in Bentley View version 10.15.0.75 and earlier (and MicroStation-based applications prior to 10.16.02.*) when parsing TIF images. The issue is a use of uninitialized memory, meaning the software reads from memory that has not been properly initialized, leading to undefined behavior. [1][2]
Exploitation
An attacker must convince a user to open a maliciously crafted TIF file or visit a page that triggers the parsing. No authentication is required, but user interaction is necessary. The attacker can craft a TIF file that triggers the uninitialized memory access, potentially leading to code execution. [1]
Impact
Successful exploitation allows arbitrary code execution in the context of the current process. This could lead to full compromise of the affected system, including confidentiality, integrity, and availability. [1][2]
Mitigation
Bentley has released version 10.16.02.* for Bentley View and MicroStation which mitigates this vulnerability. Users should update to the latest version. As a workaround, only open TIF files from trusted sources. [2]
