Security readout for executives and security teams
Plain-English summary
CVE-2022-28245 is a medium-severity Adobe Acrobat Reader issue triggered when a user opens a malicious file. It can disclose memory information and may help bypass protections like ASLR, making it more useful as part of a larger attack chain than as a standalone compromise.
Executive priority
Treat as a routine but timely desktop patching item. The business risk is mainly from phishing or document-delivery scenarios where this memory disclosure helps attackers weaken exploit mitigations in a broader campaign.
Technical view
The flaw is a CWE-125 out-of-bounds read in Acrobat Reader DC parsing of crafted files. CVSS 3.1 is 5.5: local attack vector, low complexity, no privileges, required user interaction, high confidentiality impact, no integrity or availability impact.
Likely exposure
Organizations are exposed where Adobe Acrobat Reader DC 22.001.2011x and earlier, 20.005.3033x and earlier, or 17.012.3022x and earlier are installed and users can open untrusted files.
Exploitation context
The source bundle does not identify active exploitation, and CISA KEV status is false. Exploitation requires a victim to open a malicious file. The documented impact is information disclosure that could assist mitigation bypass, not direct code execution by itself.
Researcher notes
Evidence supports an out-of-bounds read with confidentiality impact and required user interaction. The provided bundle does not include proof of active exploitation, exploit maturity, or fixed version numbers, so remediation specifics should be taken from Adobe APSB22-16.
Mitigation direction
- Review Adobe APSB22-16 for vendor remediation guidance and fixed versions.
- Update affected Acrobat Reader installations according to Adobe guidance.
- Limit opening of untrusted PDF or document files from email and web sources.
- Use endpoint controls to reduce exposure to unsolicited document attachments.
Validation and detection
- Inventory Acrobat Reader versions across managed endpoints.
- Flag versions at or below the affected 22, 20, and 17 release ranges.
- Confirm update deployment aligns with Adobe APSB22-16 guidance.
- Check vulnerability scanners for CVE-2022-28245 coverage and detections.

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.
