CVE-2026-44923: InfoScale VIOM SQLi Vulnerability

CVE-2026-44923 Overview

CVE-2026-44923 is a SQL injection vulnerability in InfoScale Veritas InfoScale Operations Manager (VIOM) web application versions prior to v9.1.3. The flaw allows remote attackers to inject crafted SQL statements through the web interface and escalate privileges within the application. The weakness is classified under CWE-89: Improper Neutralization of Special Elements used in an SQL Command. Exploitation requires no authentication and no user interaction, and the issue is reachable over the network.

Critical Impact
Remote, unauthenticated attackers can manipulate backend SQL queries through the VIOM web application to escalate privileges and access sensitive data managed by InfoScale Operations Manager.

Technical Details for CVE-2026-44923

Vulnerability Analysis

The vulnerability resides in the InfoScale Operations Manager (VIOM) web application, which constructs SQL queries using attacker-controllable input without adequate parameterization or sanitization. An attacker submits crafted input to a vulnerable endpoint, and the application appends that input directly into a SQL statement executed against the backend database.

Because the application uses the resulting query results to make authorization or role decisions, successful injection enables privilege escalation. An attacker without prior credentials can read or modify records that influence access control, gaining capabilities reserved for higher-privileged VIOM users. The attack is network-reachable and requires no user interaction.

Impact is constrained to confidentiality and integrity within the application context. The vulnerability does not directly enable code execution on the host, but VIOM manages storage and availability operations across InfoScale clusters, so privilege escalation inside the management console can disrupt downstream operations.

Root Cause

The root cause is improper neutralization of special elements within SQL statements [CWE-89]. Input received from web requests is concatenated into query strings rather than bound through prepared statements, allowing attacker-supplied SQL syntax to alter query semantics.

Attack Vector

The attack vector is network-based against the VIOM web interface. An attacker sends an HTTP request containing SQL metacharacters to a vulnerable parameter. The backend database executes the manipulated query, returning data or applying state changes that the attacker uses to gain higher privileges. No verified public proof-of-concept is currently available. Refer to the InfoScale Security Bulletin CVE-2026-44923 for technical details.

Detection Methods for CVE-2026-44923

Indicators of Compromise

HTTP requests to VIOM web endpoints containing SQL metacharacters such as ', --, ;, UNION SELECT, or encoded equivalents
Unexpected new or modified VIOM user accounts, role assignments, or privilege changes without corresponding administrative activity
Database error responses or anomalous query latency originating from VIOM application requests

Detection Strategies

Inspect web server and application logs for malformed query strings or POST bodies targeting VIOM endpoints
Deploy a Web Application Firewall (WAF) rule set tuned for SQL injection signatures in front of the VIOM management interface
Correlate authentication and authorization events with database query logs to identify privilege changes following anomalous queries

Monitoring Recommendations

Enable verbose audit logging on the VIOM backend database and forward logs to a centralized SIEM for retention and correlation
Alert on any administrative role assignment in VIOM that is not initiated from an approved administrative workstation
Monitor outbound connections from the VIOM host for unexpected data egress patterns that may indicate post-exploitation activity

How to Mitigate CVE-2026-44923

Immediate Actions Required

Upgrade VIOM to version v9.1.3 or later as directed in the vendor advisory
Restrict network access to the VIOM web console using firewall rules or VPN-only access until the patch is applied
Audit VIOM user accounts and recent role changes for signs of unauthorized privilege escalation

Patch Information

Veritas has released a fixed build in InfoScale VIOM v9.1.3. Apply the update as described in the InfoScale Security Bulletin CVE-2026-44923 and the Veritas Support Document 120571566. The same advisory also addresses CVE-2026-44924 and CVE-2026-44925, so administrators should apply the cumulative update.

Workarounds

Limit VIOM web application exposure to trusted management networks only
Place a WAF in front of the VIOM console with SQL injection signatures enabled until the upgrade is complete
Rotate VIOM administrative credentials and database service account passwords after patching

bash

# Example: restrict VIOM web access to a management subnet using iptables
iptables -A INPUT -p tcp --dport 5634 -s 10.10.20.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 5634 -j DROP
