CVE-2026-28516 in openDCIM
Summary
by MITRE • 02/28/2026
openDCIM version 23.04, through commit 4467e9c4, contains a SQL injection vulnerability in Config::UpdateParameter. The install.php and container-install.php handlers pass user-supplied input directly into SQL statements using string interpolation without prepared statements or proper input sanitation. An authenticated user can execute arbitrary SQL statements against the underlying database.

The vulnerability identified as CVE-2026-28516 represents a critical SQL injection flaw within the openDCIM application version 23.04, specifically affecting the Config::UpdateParameter functionality. This issue stems from improper input handling within the installation scripts install.php and container-install.php, where user-supplied data is directly interpolated into SQL queries without adequate sanitization or parameterization. The vulnerability exists in the commit hash 4467e9c4, indicating a regression or new introduction of insecure coding practices that bypass standard database security measures.
The technical exploitation of this vulnerability occurs through authenticated user access, meaning that an attacker must first obtain valid credentials to the system. Once authenticated, the malicious actor can manipulate the Config::UpdateParameter function to inject arbitrary SQL commands into the database layer. This flaw directly maps to CWE-89, which categorizes SQL injection vulnerabilities as weaknesses in software that allows attackers to manipulate database queries through untrusted input. The absence of prepared statements or proper input validation creates an environment where malicious SQL payloads can be executed with the privileges of the database user, potentially leading to complete database compromise.
The operational impact of this vulnerability extends beyond simple data theft, as it enables attackers to perform destructive operations including data modification, deletion, or unauthorized access to sensitive system information. An authenticated attacker could leverage this vulnerability to escalate privileges, extract confidential data, or even establish persistent backdoors within the database infrastructure. The installation scripts represent a particularly dangerous attack surface since they often run with elevated privileges and may be accessible during system deployment or maintenance phases. This vulnerability aligns with ATT&CK technique T1078.004, which covers valid accounts used for persistence, as the attacker could maintain access through manipulated database entries or compromised user credentials.
Mitigation strategies should prioritize immediate implementation of prepared statements and parameterized queries throughout the application codebase, particularly in database interaction functions. The installation scripts must be updated to validate and sanitize all user inputs before processing, implementing proper input filtering and escaping mechanisms. Network segmentation and least privilege access controls should be enforced to limit the potential damage from successful exploitation. Regular security audits and code reviews should be conducted to identify similar patterns of insecure database handling. Additionally, implementing web application firewalls and database activity monitoring can provide additional layers of protection against SQL injection attacks, while regular patch management ensures that known vulnerabilities are addressed promptly. The vulnerability underscores the critical importance of following secure coding practices and demonstrates how seemingly minor coding oversights can create significant security risks in enterprise applications.
