Security readout for executives and security teams
Plain-English summary
Bentley View 10.15.0.75 can mishandle crafted BMP images and disclose limited sensitive information from memory. Exploitation requires a user to open a malicious file or visit a malicious page, so this is mainly a workstation file-handling risk, not a remotely exploitable server issue.
Executive priority
Treat this as a low-priority but valid workstation remediation item. Address it during normal patch cycles, with faster action for teams that regularly process files from customers, partners, or unknown sources.
Technical view
The flaw is a CWE-125 out-of-bounds read in BMP parsing. Improper validation of user-supplied image data can read past an allocated buffer. The CVSS v3.0 score is 3.3 with local attack vector, required user interaction, low confidentiality impact, and no integrity or availability impact.
Likely exposure
Exposure is limited to environments running Bentley View 10.15.0.75, especially engineering or design workstations that open externally supplied files. No other Bentley products or versions are identified in the provided bundle.
Exploitation context
The provided sources do not indicate active exploitation, and the CVE is not marked KEV. Exploitation requires user interaction. The description notes possible use with other vulnerabilities for code execution, but this CVE alone is described as limited information disclosure.
Researcher notes
Evidence supports an out-of-bounds read in BMP parsing with required user interaction. The bundle does not provide fixed-version details or proof of exploitation. Avoid assuming broader Bentley exposure beyond View 10.15.0.75.
Mitigation direction
- Identify and prioritize Bentley View 10.15.0.75 installations.
- Check Bentley advisory BE-2021-0002 for vendor remediation guidance.
- Avoid opening untrusted BMP files or untrusted files containing embedded BMP content.
- Use mail and web controls to reduce delivery of suspicious engineering files.
- Harden workstations that process third-party design or image files.
Validation and detection
- Inventory endpoints for Bentley View 10.15.0.75.
- Confirm whether users open external BMP or design files in Bentley View.
- Review vulnerability scanner results for CVE-2021-46629 or Bentley View version findings.
- Verify remediation against Bentley's advisory once vendor guidance is reviewed.
- Check security monitoring for suspicious file-open events involving Bentley View.
