Detailsinfo

A vulnerability classified as critical has been found in Bentley MicroStation CONNECT 10.16.02.034. This affects an unknown functionality of the component OBJ File Parser. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Bentley MicroStation CONNECT 10.16.02.034. 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 OBJ files. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-16171.

The weakness was published 03/30/2023 as ZDI-22-594. The advisory is shared at zerodayinitiative.com. This vulnerability is uniquely identified as CVE-2022-28304 since 03/31/2022.
