Understanding CVE-2022-26887

CVE-2022-26887 is a high-impact vulnerability that affects Delta Electronics DIAEnergie software versions prior to 1.8.02.004. The vulnerability allows attackers to inject arbitrary SQL queries, access and modify database contents, and execute system commands.

What is CVE-2022-26887?

The CVE-2022-26887 vulnerability is a blind SQL injection flaw present in the DIAE_loopmapHandler.ashx of Delta Electronics DIAEnergie software. It poses a significant risk as it enables malicious actors to manipulate the software and database through unauthorized SQL queries.

The Impact of CVE-2022-26887

With a CVSS base score of 9.8 (Critical), the CVE-2022-26887 vulnerability is deemed severe due to its potential to cause high confidentiality, integrity, and availability impacts. Attackers can exploit this flaw remotely without requiring any privileges, making it a critical issue for affected systems.

Technical Details of CVE-2022-26887

The vulnerability affects Delta Electronics DIAEnergie software versions lower than 1.8.02.004. It has a LOW attack complexity and can be exploited over a network without user interaction, resulting in a CRITICAL base severity score.

Vulnerability Description

The flaw allows attackers to perform blind SQL injection attacks on the DIAE_loopmapHandler.ashx file, enabling them to execute unauthorized SQL queries, access and tamper with database records, and run system commands.

Affected Systems and Versions

Delta Electronics DIAEnergie versions prior to 1.8.02.004 are vulnerable to CVE-2022-26887. Users of these versions are at risk of exploitation by threat actors seeking unauthorized access to sensitive data.

Exploitation Mechanism

The vulnerability can be exploited over a network connection, where attackers inject malicious SQL commands via the DIAE_loopmapHandler.ashx file. This manipulation allows them to gain control over the database and execute commands on the system.

Mitigation and Prevention

To mitigate the risks associated with CVE-2022-26887, users should take immediate action to secure their systems and implement long-term security practices.

Immediate Steps to Take

Update Delta Electronics DIAEnergie software to Version 1.08.02.004, as this release addresses the vulnerability.
Minimize network exposure for control system devices and restrict Internet access.
Segment control system networks, employ firewalls, and isolate them from business networks.

Long-Term Security Practices

Utilize application firewalls to detect and prevent Path Traversal and SQL Injection attacks.
Avoid connecting programming software to networks other than the intended device network.
When remote access is necessary, use secure methods like Virtual Private Networks (VPNs) to safeguard data transmission.
Regularly apply security patches and updates to prevent future vulnerabilities.
