CVE-2024-32737: CyberPower PowerPanel SQLi Vulnerability

CVE-2024-32737 Overview

CVE-2024-32737 is a SQL injection vulnerability in CyberPower PowerPanel Enterprise versions prior to v2.8.3. The flaw resides in the query_contract_result function within the MCUDBHelper component. An unauthenticated remote attacker can craft malicious SQL statements that the application passes directly to the backend database. Successful exploitation leaks sensitive information stored within the PowerPanel Enterprise database. The vulnerability is tracked under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command). The Exploit Prediction Scoring System (EPSS) places this issue in the 97.95 percentile, indicating high relative likelihood of exploitation activity.

Critical Impact

Unauthenticated remote attackers can extract sensitive data from PowerPanel Enterprise databases without user interaction or credentials.

Affected Products

• CyberPower PowerPanel Enterprise versions prior to v2.8.3
• Deployments on Windows platforms per the published CPE
• Environments using the MCUDBHelperquery_contract_result function

Discovery Timeline

• 2024-05-14 - CVE-2024-32737 published to the National Vulnerability Database (NVD)

Technical Details for CVE-2024-32737

Vulnerability Analysis

The vulnerability is a classic SQL injection flaw exposed through a network-reachable interface in PowerPanel Enterprise. PowerPanel Enterprise is CyberPower's centralized management software for uninterruptible power supplies (UPS) and power distribution units. The MCUDBHelper component handles database interactions for monitoring and contract-related queries. The query_contract_result function accepts attacker-controlled input and concatenates it into a SQL statement without proper parameterization or sanitization. Because the affected endpoint does not require authentication, any attacker with network access to the management interface can reach the vulnerable code path. Exploitation results in confidentiality impact only, consistent with information disclosure through query result extraction.

Root Cause

The root cause is improper neutralization of special elements within input passed to the query_contract_result function (CWE-89). The function does not use prepared statements or parameter binding when constructing SQL queries. Attacker-supplied data is treated as part of the query syntax rather than as data values.

Attack Vector

An unauthenticated remote attacker sends crafted requests over the network to the PowerPanel Enterprise management service. The malicious SQL fragments are processed by the vulnerable function, enabling techniques such as UNION-based extraction, boolean-based blind injection, or error-based disclosure. Refer to the Tenable Threat Research Advisory for additional technical context.

Detection Methods for CVE-2024-32737

Indicators of Compromise

• Unusual inbound HTTP or API requests to PowerPanel Enterprise endpoints containing SQL meta-characters such as ', --, UNION SELECT, or OR 1=1
• Database query logs showing malformed or unexpected statements originating from the MCUDBHelper component
• Spikes in request volume or response size from the query_contract_result handler

Detection Strategies

• Inspect web server and application logs for parameter values targeting contract-related endpoints with SQL syntax patterns
• Deploy web application firewall (WAF) rules tuned for SQL injection payloads against the PowerPanel management interface
• Correlate authentication telemetry with database query patterns to flag unauthenticated sessions producing query activity

Monitoring Recommendations

• Enable verbose query logging on the database backing PowerPanel Enterprise and alert on syntax errors
• Restrict and monitor network access to the PowerPanel Enterprise management port from non-administrative networks
• Forward application and database logs to a centralized analytics platform for anomaly detection

How to Mitigate CVE-2024-32737

Immediate Actions Required

• Upgrade CyberPower PowerPanel Enterprise to version 2.8.3 or later
• Restrict network reachability of the PowerPanel Enterprise management interface to trusted administrative subnets
• Review database and application logs for prior exploitation indicators dating back to before the patch was applied

Patch Information

CyberPower addressed the issue in PowerPanel Enterprise v2.8.3. Refer to the CyberPower File Release Note for upgrade packages and release notes. Additional research details are available in the Tenable Threat Research Advisory.

Workarounds

• Place the PowerPanel Enterprise server behind a WAF configured to block SQL injection signatures until patching is complete
• Apply network segmentation and firewall rules to limit access to authenticated operators only
• Disable external exposure of the management service if upgrade cannot be performed immediately
