CVE-2026-2998 Overview
A DLL Hijacking vulnerability has been identified in ERP software developed by eAI Technologies. This security flaw allows authenticated local attackers to place a maliciously crafted DLL file in the same directory as the ERP program executable. When the application loads this rogue DLL, it executes arbitrary code with the privileges of the running process, potentially compromising system integrity and confidentiality.
Critical Impact
Authenticated local attackers can achieve arbitrary code execution by exploiting insecure DLL search order behavior, potentially leading to full system compromise, data theft, or lateral movement within enterprise environments.

Technical Details for CVE-2026-2998
Vulnerability Analysis
This vulnerability is classified under CWE-426 (Untrusted Search Path), which occurs when an application searches for critical resources using an externally-supplied search path that can point to resources outside the application's control. In the context of Windows applications, this commonly manifests as DLL Hijacking where the application loads a DLL from an untrusted directory before checking system directories.
The eAI Technologies ERP application fails to properly specify the full path when loading dynamic-link libraries, instead relying on the Windows DLL search order. This allows an attacker with local access to plant a malicious DLL in the application's directory or current working directory, which takes precedence over legitimate system DLLs during the loading process.
Root Cause
The root cause of this vulnerability lies in the application's improper implementation of DLL loading mechanisms. Instead of using secure loading practices such as specifying absolute paths or utilizing the SetDllDirectory("") API to remove the current directory from the search path, the ERP software relies on the default Windows DLL search order. This design flaw creates an opportunity for attackers to inject malicious code through strategically placed DLL files.
Attack Vector
The attack requires local access and valid authentication credentials on the target system. An attacker must:
- Identify which DLLs the ERP application attempts to load without full path specification
- Create a malicious DLL with the same name as the targeted legitimate DLL
- Place the crafted DLL in the application's directory or a directory that appears earlier in the search path
- Wait for or trigger the ERP application to load the malicious DLL
When the vulnerable application executes and attempts to load the required DLL, Windows follows its default search order, loading the attacker's malicious DLL first. The code within the malicious DLL then executes with the same privileges as the ERP application, enabling arbitrary code execution.
Detection Methods for CVE-2026-2998
Indicators of Compromise
- Unexpected DLL files appearing in the eAI Technologies ERP installation directory that do not match the vendor's original software distribution
- DLL files with legitimate names but anomalous file hashes, sizes, or digital signature mismatches in application directories
- Process execution anomalies where the ERP application spawns unexpected child processes or makes unusual network connections
Detection Strategies
- Monitor file system activity in the ERP application directory for newly created or modified DLL files using endpoint detection and response (EDR) solutions
- Implement application whitelisting to prevent unauthorized DLLs from being loaded by the ERP application
- Configure Windows Event Logging to capture DLL load events (Event ID 7) and correlate with known-good DLL hashes
Monitoring Recommendations
- Deploy SentinelOne's behavioral AI engine to detect anomalous code execution patterns originating from the ERP application process
- Establish baseline DLL loading behavior for the eAI Technologies ERP application and alert on deviations
- Monitor for privilege escalation attempts following DLL load events in ERP-related processes
How to Mitigate CVE-2026-2998
Immediate Actions Required
- Restrict write permissions on the ERP application installation directory to prevent unauthorized users from placing malicious DLL files
- Implement least privilege principles for user accounts that interact with the ERP system
- Apply application control policies to prevent execution of unsigned or untrusted DLLs within the ERP directory structure
- Monitor for vendor security updates from eAI Technologies and apply patches as they become available
Patch Information
No specific patch information is currently available from eAI Technologies. Organizations should monitor the TW-CERT Security Advisory and the TW-CERT Database Report for updates and remediation guidance from the vendor.
Workarounds
- Configure strict NTFS permissions on the ERP installation directory, allowing only administrators to write files while granting read and execute permissions to standard users
- Use Windows Software Restriction Policies (SRP) or AppLocker to block unauthorized DLL execution in application directories
- Consider running the ERP application in a sandboxed or virtualized environment to limit the impact of potential exploitation
- Implement SentinelOne's application control features to enforce DLL loading policies and prevent malicious library injection
# Example: Restrict write permissions on ERP directory
icacls "C:\Program Files\eAI Technologies\ERP" /inheritance:r
icacls "C:\Program Files\eAI Technologies\ERP" /grant:r Administrators:(OI)(CI)F
icacls "C:\Program Files\eAI Technologies\ERP" /grant:r Users:(OI)(CI)RX
