CVE-2026-54368: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') in Gladinet CentreStack
CentreStack before 17.4 contains a SQL injection vulnerability in GladDBFiles.SearchEx() and SearchExUnder() that allows authenticated attackers to execute arbitrary SQL statements by supplying a crafted x-glad-filter request header through the jsondir API endpoint. Attackers can exploit unsanitized interpolation of the Field parameter directly into SQL query strings to write arbitrary files to the server filesystem via PostgreSQL lo_from_bytea() and lo_export() functions, enabling remote code execution.
AI Analysis
Technical Summary
CVE-2026-54368 is a SQL injection vulnerability affecting CentreStack before version 17.4. The issue arises from improper neutralization of special elements in SQL commands within the GladDBFiles.SearchEx() and SearchExUnder() functions. Authenticated attackers can supply a crafted x-glad-filter request header through the jsondir API endpoint, causing unsanitized interpolation of the Field parameter directly into SQL query strings. This allows execution of arbitrary SQL statements, including the ability to write arbitrary files to the server filesystem using PostgreSQL's lo_from_bytea() and lo_export() functions, which can lead to remote code execution.
Potential Impact
An authenticated attacker can execute arbitrary SQL commands on the affected CentreStack server, including writing files to the server filesystem. This can lead to remote code execution, compromising the confidentiality, integrity, and availability of the system. The vulnerability has a high severity with a CVSS 4.0 score of 8.7, indicating significant potential impact if exploited.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict authenticated access to the jsondir API endpoint and monitor for suspicious activity involving crafted x-glad-filter headers. Avoid exposing the vulnerable API to untrusted networks.
