Security readout for executives and security teams
Plain-English summary
Bentley View 10.15.0.75 can mishandle JP2 image files and read memory beyond an allocated buffer. An attacker would need a user to open a malicious file or visit a malicious page. The direct impact is limited information disclosure, but the source notes it may support code execution when chained with other vulnerabilities.
Executive priority
Treat as a low-severity workstation risk unless Bentley View is widely used with untrusted files. Prioritize inventory and vendor-guidance checks, especially in engineering teams that receive outside project files.
Technical view
CVE-2021-46632 is a CWE-125 out-of-bounds read in JP2 image parsing in Bentley View 10.15.0.75. The published CVSS vector is 3.3 low: local attack vector, low complexity, no privileges, user interaction required, low confidentiality impact, and no integrity or availability impact.
Likely exposure
Exposure is most likely on workstations where Bentley View 10.15.0.75 is installed and users open JP2 images or related design files from external or untrusted sources.
Exploitation context
The bundle does not show CISA KEV listing or active exploitation. Exploitation requires user interaction. ZDI reported the issue as ZDI-22-219 and notes possible use with other vulnerabilities for code execution, but this source alone does not prove active attacks.
Researcher notes
The key technical issue is bounds validation failure in JP2 parsing. Available evidence supports information disclosure with required user interaction. Do not assume standalone code execution; the source only states code execution may be possible when chained with other vulnerabilities.
Mitigation direction
- Check Bentley advisory BE-2021-0008 for official remediation guidance.
- Inventory and prioritize systems running Bentley View 10.15.0.75.
- Restrict opening JP2 or design files from untrusted sources.
- Use email and web filtering to reduce malicious file delivery.
- Consider isolating affected workstations until vendor guidance is applied.
Validation and detection
- Confirm whether Bentley View 10.15.0.75 is present in software inventory.
- Review file-handling workflows involving JP2 images and external design files.
- Verify remediation status against Bentley advisory BE-2021-0008.
- Check endpoint controls for blocking or quarantining suspicious JP2 files.

Out-of-bounds Read
Out-of-bounds Read represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
