CVE-2026-14913 Overview
CVE-2026-14913 is a SQL Injection vulnerability [CWE-89] in ZohoCorp ManageEngine OpManager and Firewall Analyzer. The flaw resides in the Rule Management Search Reports component and affects versions 12.8.669 and below. Authenticated attackers with low privileges can inject arbitrary SQL statements through the network to read, modify, or delete database contents. The vulnerability requires no user interaction and can compromise the confidentiality, integrity, and availability of the underlying database.
Critical Impact
Authenticated remote attackers can execute arbitrary SQL queries against the ManageEngine backend database, exposing sensitive network monitoring data and rule configurations.
Affected Products
- ZohoCorp ManageEngine OpManager versions 12.8.669 and below
- ZohoCorp ManageEngine Firewall Analyzer versions 12.8.669 and below
- Rule Management Search Reports module

Technical Details for CVE-2026-14913
Vulnerability Analysis
The vulnerability exists in the Rule Management Search Reports feature of ManageEngine OpManager and Firewall Analyzer. User-supplied input passed to the search reporting endpoint is concatenated into SQL statements without proper parameterization or sanitization. Authenticated attackers with low-privilege access can craft malicious search parameters that alter the intended SQL query logic. Successful exploitation grants access to arbitrary database records, including firewall rule metadata, device inventories, and administrator-managed configurations.
The attack vector is network-based and requires no user interaction. Because both products share the affected component, environments running either OpManager or Firewall Analyzer are exposed. Attackers who obtain valid credentials through phishing, credential stuffing, or reuse can leverage this flaw to escalate their impact well beyond normal user scope.
Root Cause
The root cause is improper neutralization of special elements used in a SQL command [CWE-89]. The Rule Management Search Reports handler builds database queries from client-supplied strings without using prepared statements or strict input validation. This allows attacker-controlled data to be interpreted as SQL syntax.
Attack Vector
Exploitation requires network access to the ManageEngine web interface and a valid authenticated session with low privileges. The attacker submits a crafted search parameter to the Rule Management Search Reports endpoint. The injected payload modifies the underlying query to extract data, enumerate schemas, or perform destructive operations depending on database permissions granted to the application service account.
No public proof-of-concept exploit is currently available. Refer to the ManageEngine Security Advisory CVE-2026-14913 for vendor-provided technical details.
Detection Methods for CVE-2026-14913
Indicators of Compromise
- Unexpected SQL syntax characters such as ', --, ;, UNION, or SELECT in web server access logs targeting Rule Management endpoints
- Anomalous database query patterns originating from the OpManager or Firewall Analyzer application service account
- Sudden spikes in outbound data volume from ManageEngine hosts following authenticated user sessions
- Unusual read access to firewall rule tables or configuration schemas outside normal administrative workflows
Detection Strategies
- Enable database query logging on the ManageEngine backend and alert on syntactically malformed or unusually long queries from the application tier
- Deploy web application firewall rules that inspect POST and GET parameters to Rule Management Search Reports endpoints for SQL injection signatures
- Correlate authentication events with subsequent database activity to identify low-privilege accounts issuing administrative-level queries
Monitoring Recommendations
- Monitor ManageEngine application and audit logs for repeated failed searches or malformed reporting requests
- Track process execution and outbound network connections from the ManageEngine server for signs of post-exploitation activity
- Baseline normal user query behavior and alert on deviations, especially from accounts with limited operational scope
How to Mitigate CVE-2026-14913
Immediate Actions Required
- Upgrade ManageEngine OpManager and Firewall Analyzer to the fixed build published in the vendor advisory
- Restrict network access to the ManageEngine management interface to trusted administrative subnets only
- Rotate credentials for any accounts with access to the affected products and enforce multi-factor authentication
- Audit database logs for signs of prior exploitation targeting the Rule Management Search Reports feature
Patch Information
ZohoCorp has published a security advisory addressing this vulnerability. Administrators must upgrade to a build later than 12.8.669. Full remediation guidance and download links are available at the ManageEngine Security Advisory CVE-2026-14913.
Workarounds
- Limit the number of authenticated users who can access the Rule Management Search Reports functionality
- Place the ManageEngine web console behind a reverse proxy with SQL injection filtering enabled
- Apply least-privilege database permissions to the ManageEngine service account to reduce impact of successful injection
# Example firewall restriction limiting management interface to admin subnet
iptables -A INPUT -p tcp --dport 8060 -s 10.0.10.0/24 -j ACCEPT
iptables -A INPUT -p tcp --dport 8060 -j DROP
