Description
OriginLab OriginPro OPJU File Parsing Out-Of-Bounds Write Remote Code Execution Vulnerability. This vulnerability allows remote attackers to execute arbitrary code on affected installations of OriginLab OriginPro. 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 OPJU files. The issue results from the lack of proper validation of user-supplied data, which can result in a write past the end of an allocated data structure. An attacker can leverage this vulnerability to execute code in the context of the current process. . Was ZDI-CAN-29331.

Executive Summary

CVE-2026-18288 is an out-of-bounds write vulnerability in OriginLab OriginPro that allows remote attackers to execute arbitrary code. The flaw occurs during the parsing of OPJU project files due to insufficient validation of user-supplied data, leading to heap corruption. Exploitation requires user interaction, such as opening a malicious OPJU file.

Detection Guidance

This vulnerability involves malicious OPJU files triggering an out-of-bounds write during parsing in OriginLab OriginPro. Detection requires monitoring for suspicious file parsing activities or unusual memory corruption events in OriginPro processes. Check for crashes or heap corruption logs when opening OPJU files.

Impact Analysis

This vulnerability could allow an attacker to execute arbitrary code on your system if you open a specially crafted OPJU file. This could lead to unauthorized access, data theft, or system compromise. The impact is high as it affects confidentiality, integrity, and availability of the system.

Compliance Impact

This vulnerability could potentially impact compliance with GDPR and HIPAA by enabling arbitrary code execution through malicious OPJU files. If exploited, it may lead to unauthorized data access, modification, or exfiltration, violating confidentiality and integrity requirements under these regulations.

Mitigation Strategies

Update OriginLab OriginPro to version 2026b SR1 or later immediately. Avoid opening OPJU files from untrusted sources. Disable automatic file opening features if possible. Monitor for suspicious activity related to OriginPro processes.
