CVE-2025-12465: QuickCMS Blind SQL Injection Vulnerability

CVE-2025-12465 Overview

A Blind SQL injection vulnerability has been identified in QuickCMS. This vulnerability stems from improper neutralization of input provided by a high-privileged user into the aFilesDelete parameter, allowing for Blind SQL Injection attacks. The vulnerability requires high-privileged access to exploit but can lead to significant database compromise.

The vendor was notified early about this vulnerability but did not respond with details regarding the vulnerability or the vulnerable version range. Only version 6.8 was tested and confirmed as vulnerable; other versions were not tested and might also be affected.

Critical Impact

This HIGH severity Blind SQL Injection vulnerability (CVSS 8.6) enables attackers with high-privileged access to extract sensitive database information, modify data, or potentially compromise the underlying database server through time-based or boolean-based blind SQL injection techniques.

Affected Products

• QuickCMS version 6.8 (confirmed vulnerable)
• Other QuickCMS versions (potentially vulnerable - not tested)

Technical Details for CVE-2025-12465

Vulnerability Analysis

This vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), commonly known as SQL Injection. The Blind SQL Injection variant occurs in the aFilesDelete functionality of QuickCMS, where user-supplied input is not properly sanitized before being incorporated into SQL queries.

With a CVSS 4.0 score of 8.6 (HIGH), the vulnerability presents significant risk characteristics:

The EPSS (Exploit Prediction Scoring System) indicates a probability of 0.036% with a percentile ranking of 10.388, suggesting relatively low current exploitation activity in the wild.

Root Cause

The root cause of this vulnerability is insufficient input validation and sanitization in the aFilesDelete parameter handling code. When processing file deletion requests, the application directly incorporates user-controlled input into SQL queries without proper parameterization or escaping. This allows attackers to inject malicious SQL commands that are executed against the backend database.

The improper neutralization allows special SQL characters and commands to be interpreted as part of the query structure rather than as literal data values.

Attack Vector

The attack vector is network-based, requiring authenticated access with high privileges. An attacker with administrative or elevated privileges can exploit this vulnerability by manipulating the aFilesDelete parameter to inject SQL commands.

In a Blind SQL Injection attack against this parameter, the attacker cannot directly see the query results but can infer information through:

• Boolean-based blind injection: Observing different application responses based on whether injected conditions evaluate to true or false
• Time-based blind injection: Measuring response delays when injecting time-delay functions like SLEEP() or WAITFOR DELAY

The attacker would craft malicious input within the aFilesDelete parameter, leveraging SQL metacharacters to break out of the intended query context and append additional SQL commands. Through iterative probing, sensitive database contents can be extracted character by character.

For technical details and additional information, refer to the CERT advisory.

Detection Methods for CVE-2025-12465

Indicators of Compromise

• Unusual or malformed requests to the aFilesDelete endpoint containing SQL metacharacters (single quotes, double dashes, semicolons)
• Increased database query execution times indicating time-based SQL injection probing
• Multiple sequential requests to the same endpoint with slight parameter variations (characteristic of blind SQL injection enumeration)
• Database error logs showing syntax errors or unexpected query patterns
• Administrative user accounts exhibiting anomalous file deletion request patterns

Detection Strategies

Organizations should implement multiple layers of detection to identify potential exploitation attempts:

Web Application Firewall (WAF) Rules: Configure WAF rules to detect SQL injection patterns in request parameters, including common SQL keywords (UNION, SELECT, SLEEP, WAITFOR), comment sequences (--, /**/), and encoded variants.

Database Activity Monitoring: Enable query logging and monitor for unusual patterns such as:

• Queries with timing functions (SLEEP(), BENCHMARK(), WAITFOR DELAY)
• Queries with boolean logic patterns (AND 1=1, OR 1=1)
• Increased query volume from the application user account

Application Log Analysis: Monitor web server access logs for requests to the vulnerable endpoint with suspicious parameter values or unusual request frequencies.

Monitoring Recommendations

1. Enable detailed logging for all requests to QuickCMS administrative endpoints
2. Implement rate limiting on administrative functions including file deletion
3. Configure alerts for database queries exceeding normal execution time thresholds
4. Deploy SentinelOne Singularity Platform for real-time endpoint monitoring and behavioral analysis
5. Establish baseline patterns for normal administrative activity to detect anomalous behavior
6. Monitor for data exfiltration indicators that may follow successful SQL injection

How to Mitigate CVE-2025-12465

Immediate Actions Required

• Restrict network access to QuickCMS administrative interfaces to trusted IP addresses only
• Implement Web Application Firewall (WAF) rules to block SQL injection patterns targeting the aFilesDelete parameter
• Review and audit all high-privileged user accounts for signs of compromise
• Enable comprehensive logging and monitoring on the QuickCMS installation
• Consider temporarily disabling the file deletion functionality until a patch is available
• Apply the principle of least privilege to all database connections used by QuickCMS

Patch Information

At the time of publication, the vendor (QuickCMS) has not responded to vulnerability disclosure notifications. No official patch information is currently available. Organizations should monitor the vendor's website and the CERT advisory for updates on patch availability.

Until an official patch is released, organizations are advised to implement the workarounds and mitigations described below to reduce exploitation risk.

Workarounds

Since no official patch is currently available, implement the following defensive measures:

Input Validation: If source code access is available, implement parameterized queries (prepared statements) for all database operations, particularly those involving the aFilesDelete functionality.

Access Restrictions: Limit administrative access to the QuickCMS interface through network segmentation and IP whitelisting:

# Example: Apache .htaccess restriction for admin directory
<Directory "/var/www/quickcms/admin">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from 10.0.0.0/8
</Directory>

WAF Configuration: Deploy Web Application Firewall rules to filter malicious input:

# Example: ModSecurity rule to detect SQL injection attempts
SecRule ARGS:aFilesDelete "@detectSQLi" \
    "id:100001,\
    phase:2,\
    deny,\
    status:403,\
    log,\
    msg:'SQL Injection attempt detected in aFilesDelete parameter',\
    severity:'CRITICAL'"

Organizations should continue monitoring for official vendor guidance and apply patches as soon as they become available.
