CVE-2021-34912
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 JT files. Crafted data in a JT file can trigger a read past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-14885.
AI Insight

Bentley View 10.15.0.75 JT file parsing out-of-bounds read allows remote code execution via crafted file.
Vulnerability
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Bentley View 10.15.0.75. The flaw exists in the parsing of JT files, where crafted data can trigger a read past the end of an allocated buffer. This out-of-bounds read can be exploited when the user opens a malicious JT file or visits a malicious page. [1][2]
Exploitation
An attacker must deliver a specially crafted JT file to the target user, who must either open the file or visit a page that triggers the parsing. No authentication is required, but user interaction is necessary. The vulnerability can be exploited remotely. [1][2]
Impact
Successful exploitation allows an attacker to execute arbitrary code in the context of the current process. This can lead to complete compromise of confidentiality, integrity, and availability of the affected system, as the attacker gains the same privileges as the user running Bentley View. [1][2]
Mitigation
Bentley has addressed this vulnerability in a subsequent version of Bentley View. Users should update to the latest version as recommended in Bentley advisory BE-2021-0005. No workarounds are disclosed in the available references. [1]
