1. EXECUTIVE SUMMARY
- CVSS v3 7.8
- ATTENTION: Low skill level to exploit
- Vendor: Delta Electronics (Delta)
- Equipment: TPEditor
- Vulnerabilities: Untrusted Pointer Dereference, Out-of-bounds Write
2. RISK EVALUATION
Successful exploitation of these vulnerabilities could allow an attacker to execute code under the privileges of the application.
3. TECHNICAL DETAILS
3.1 AFFECTED PRODUCTS
The following versions of TPEditor, programming software for Delta text panels, are affected:
- TPEditor: v1.98 and prior
3.2 VULNERABILITY OVERVIEW
An untrusted pointer dereference has been identified in the way the application processes project files, allowing an attacker to craft a special project file that may permit arbitrary code execution.
The affected product is vulnerable to two out-of-bounds write instances in the way it processes project files, allowing an attacker to craft a special project file that may permit arbitrary code execution.

kimiya, working with Trend Micro’s Zero Day Initiative, reported these vulnerabilities to CISA.
Delta recommends updating to v1.98.03 or later.
CISA recommends users take the following measures to protect themselves from social engineering attacks:
- Open project files only from trusted sources.
- Do not click web links or open unsolicited attachments in email messages.
- Refer to Recognizing and Avoiding Email Scams for more information on avoiding email scams.
- Refer to Avoiding Social Engineering and Phishing Attacks for more information on social engineering attacks.
be updated to the most current version available. Also recognize that VPN is only as secure as the connected devices.
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage on us-cert.cisa.gov. Several recommended practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage on us-cert.cisa.gov in the Technical Information Paper, ICS-TIP-12-146-01B–Targeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing any suspected malicious activity should follow their established internal procedures and report their findings to CISA for tracking and correlation against other incidents.
No known public exploits specifically target these vulnerabilities. These vulnerabilities are not exploitable remotely.
