CVE-2024-6748 Overview
CVE-2024-6748 is an authenticated SQL injection vulnerability affecting Zohocorp ManageEngine OpManager, OpManager Plus, OpManager MSP, and RMM versions 128317 and below. The flaw resides in the URL monitoring functionality and allows authenticated attackers to inject SQL statements into backend database queries. The weakness is classified under CWE-89, Improper Neutralization of Special Elements used in an SQL Command. Successful exploitation can expose sensitive monitoring data, modify database records, and impact the availability of network management operations.
Critical Impact
Authenticated attackers can execute arbitrary SQL queries against the ManageEngine database, exposing monitored infrastructure data and credentials stored by the platform.

Technical Details for CVE-2024-6748
Vulnerability Analysis
The vulnerability affects the URL monitoring component in ManageEngine OpManager and related products. URL monitoring lets administrators track HTTP and HTTPS endpoints for availability, response codes, and content. User-supplied parameters submitted to this feature are passed into SQL queries without adequate sanitization or parameterization. An authenticated user with access to the monitoring interface can inject SQL syntax that alters query execution.
The EPSS probability of 23.784% (97th percentile) reflects significant exploitation interest for this class of ManageEngine flaw. ManageEngine products are frequently targeted because they hold privileged inventory data and credentials for managed devices.
Root Cause
The root cause is improper neutralization of special characters in SQL statements built from URL monitoring input. The application constructs queries via string concatenation instead of prepared statements with bound parameters. Attacker-controlled input reaches the database interpreter as executable SQL syntax rather than inert data.
Attack Vector
Exploitation requires network access to the ManageEngine web console and valid low-privilege credentials. The attacker submits crafted input to a URL monitoring parameter, causing the injected SQL fragment to execute in the query context. From there, the attacker can enumerate database contents, extract stored credentials for monitored hosts, and modify configuration data. See the ManageEngine Security Advisory CVE-2024-6748 for vendor-provided details.
Detection Methods for CVE-2024-6748
Indicators of Compromise
- Unexpected SQL syntax such as UNION SELECT, --, ;, or CHAR( in URL monitoring request parameters captured by web server or reverse proxy logs.
- Anomalous database queries originating from the OpManager application account referencing system tables or credential-bearing tables.
- New or modified URL monitor definitions created by non-administrative accounts.
- Outbound connections from the OpManager host to unfamiliar destinations shortly after authenticated console activity.
Detection Strategies
- Inspect ManageEngine access logs for authenticated POST or GET requests to URL monitoring endpoints containing SQL metacharacters.
- Correlate application-tier logs with database audit logs to identify query patterns inconsistent with normal monitoring operations.
- Deploy web application firewall signatures for SQL injection payloads targeting ManageEngine URI paths.
Monitoring Recommendations
- Enable database query logging on the backend used by OpManager and alert on queries that reference authentication or credential tables from the application account.
- Monitor authentication logs for privilege changes or new local accounts created after suspicious console activity.
- Track file writes and process launches on the OpManager server that follow web session activity from the monitoring feature.
How to Mitigate CVE-2024-6748
Immediate Actions Required
- Upgrade Zohocorp ManageEngine OpManager, OpManager Plus, OpManager MSP, and RMM to a build higher than 128317 as instructed in the vendor advisory.
- Rotate credentials stored within ManageEngine for managed devices, SNMP communities, and API integrations after patching.
- Review URL monitor definitions and audit logs for unauthorized changes since deployment.
Patch Information
Zohocorp addressed CVE-2024-6748 in builds above 128317 for OpManager, OpManager Plus, OpManager MSP, and RMM. Administrators must apply the vendor-supplied service pack referenced in the ManageEngine security advisory. No effective code-level workaround exists outside of the vendor patch.
Workarounds
- Restrict access to the ManageEngine web console to trusted management networks using firewall or VPN controls.
- Enforce least privilege on ManageEngine accounts and remove URL monitoring permissions from users who do not require them.
- Require multi-factor authentication for all ManageEngine console logins to reduce the value of credential theft.
