CVE-2025-52577: Advantech iView SQL Injection Vulnerability

CVE-2025-52577 Overview

CVE-2025-52577 is a SQL injection vulnerability in Advantech iView, a network management software used in industrial control system (ICS) environments. The flaw resides in the NetworkServlet.archiveTrapRange() method, which fails to properly sanitize input parameters. An authenticated attacker with user-level privileges can inject SQL statements and potentially execute code in the context of the nt authority\local service account. The vulnerability is tracked under CWE-89 and is documented in the CISA ICS Advisory ICSA-25-191-08.

Critical Impact
Authenticated attackers can chain SQL injection with command execution to gain code execution on iView servers managing industrial network infrastructure.

Affected Products

Advantech iView (network management application)
Deployments exposing the NetworkServlet endpoint to authenticated users
ICS environments running vulnerable iView builds prior to the vendor fix

Technical Details for CVE-2025-52577

Vulnerability Analysis

The vulnerability exists in the archiveTrapRange() method of NetworkServlet, a component that handles SNMP trap archival requests within Advantech iView. The servlet accepts user-supplied parameters that are concatenated into SQL queries without parameterization or input validation. An authenticated user with low privileges can submit crafted parameters that break out of the intended query context.

Because iView runs with nt authority\local service privileges on Windows hosts, successful SQL injection can be escalated to operating system command execution. Database engines exposed to the service typically permit stacked queries or extended stored procedures, which is the mechanism through which code execution becomes possible. The flaw is exploitable over the network and requires no user interaction beyond the attacker's own authenticated session.

Root Cause

The root cause is improper neutralization of special elements used in SQL commands [CWE-89]. The archiveTrapRange() method builds SQL statements through string concatenation of HTTP request parameters. The absence of prepared statements or input filtering allows attacker-controlled syntax to alter query semantics and reach administrative database functionality.

Attack Vector

Exploitation requires authenticated network access to the iView web interface. The attacker submits an HTTP request to the NetworkServlet endpoint invoking the archiveTrapRange action with malicious parameter values. The injected SQL payload executes inside the database session and, where the database supports it, triggers OS command execution through stored procedures or file-write primitives. Technical specifics are documented in the CISA ICS Advisory ICSA-25-191-08.

No verified public proof-of-concept code has been released. See the advisory for additional technical context.

Detection Methods for CVE-2025-52577

Indicators of Compromise

HTTP requests targeting NetworkServlet with archiveTrapRange action parameters containing SQL metacharacters such as single quotes, semicolons, or UNION SELECT constructs.
Unexpected child processes spawned by the iView service running under nt authority\local service.
Database error messages or stack traces in iView logs referencing archiveTrapRange().
Outbound connections from the iView host to attacker infrastructure following anomalous servlet requests.

Detection Strategies

Inspect web server and application logs for NetworkServlet requests containing SQL injection payloads, encoded characters, or unusually long parameter values.
Monitor the iView application process for execution of cmd.exe, powershell.exe, or scripting interpreters, which are not expected children of the service.
Correlate authentication events with subsequent SQL errors to identify low-privilege accounts probing the endpoint.

Monitoring Recommendations

Enable verbose logging on the iView application and the backing database to capture query patterns and authentication context.
Forward iView logs, Windows Security events, and Sysmon process creation telemetry to a central SIEM for correlation.
Alert on any process tree where the iView service executes shell, scripting, or network utilities.

How to Mitigate CVE-2025-52577

Immediate Actions Required

Apply the vendor firmware and software update referenced in the Advantech Firmware Update advisory.
Restrict network access to the iView management interface to trusted administrative networks only.
Audit iView user accounts, remove inactive users, and rotate credentials for accounts with access to the application.
Review iView and database logs for prior exploitation attempts against NetworkServlet.

Patch Information

Advantech has released an updated iView build that addresses the SQL injection in NetworkServlet.archiveTrapRange(). Administrators should download and install the fixed version from the Advantech Firmware Update portal. CISA tracks remediation guidance in ICS Advisory ICSA-25-191-08.

Workarounds

Place the iView server behind a VPN or jump host so the web interface is not reachable from general user networks.
Deploy a web application firewall (WAF) rule set that blocks SQL injection patterns directed at /NetworkServlet endpoints.
Run the iView service under a least-privileged account where supported, rather than the default local service context, to reduce post-exploitation impact.
Disable or block the archiveTrapRange action at the network layer if not required by operational workflows.

bash

# Example WAF/iptables restriction limiting iView access to a management subnet
iptables -A INPUT -p tcp --dport 8080 -s 10.10.0.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 8080 -j DROP
