CVE-2025-7568: Qianfox Foxcms SQL Injection Vulnerability

CVE-2025-7568 Overview

CVE-2025-7568 is a SQL injection vulnerability affecting qianfox FoxCMS versions up to 1.2.5. The flaw resides in the batchCope function of the app/admin/controller/Video.php file. Attackers can manipulate the ids argument to inject arbitrary SQL statements against the backend database. The vulnerability is exploitable remotely and requires low-privilege authentication. The exploit has been publicly disclosed, increasing the likelihood of opportunistic attacks. The vendor was contacted before public disclosure but did not respond, leaving deployments without an official fix.

Critical Impact

Authenticated remote attackers can inject SQL through the ids parameter in the admin Video controller, enabling unauthorized data access, modification, and potential further compromise of the FoxCMS database.

Affected Products

• qianfox FoxCMS versions up to and including 1.2.5
• app/admin/controller/Video.php component
• Deployments exposing the FoxCMS admin interface to untrusted networks

Technical Details for CVE-2025-7568

Vulnerability Analysis

The vulnerability is classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component) and manifests as SQL injection. The batchCope function in app/admin/controller/Video.php handles batch operations on video records identified by the ids parameter. The function passes user-supplied ids values into a SQL query without adequate sanitization or parameterization. An authenticated attacker with admin access can craft ids payloads containing SQL metacharacters to alter query logic. The EPSS score of 0.216% indicates a low but non-zero probability of exploitation in the near term.

Root Cause

The root cause is missing input validation and lack of prepared statements when constructing SQL queries from the ids argument. FoxCMS concatenates the parameter directly into the query string instead of binding it as a typed parameter. This pattern is common in PHP applications that build dynamic SQL for batch operations on comma-separated identifier lists.

Attack Vector

The attack vector is network-based and requires low-privilege authentication to the FoxCMS admin panel. An attacker sends a crafted HTTP request to the endpoint handling batchCope, supplying a malicious ids value. The injected SQL executes within the database context of the FoxCMS application user. Refer to the GitHub CVE Documentation and VulDB entry #316266 for technical proof-of-concept details.

Detection Methods for CVE-2025-7568

Indicators of Compromise

• HTTP requests to the FoxCMS admin Video controller containing SQL metacharacters such as ', --, UNION, or SLEEP( within the ids parameter
• Unexpected database errors or extended query response times correlated with admin batch operations
• Unauthorized changes to video records or other database tables accessible to the FoxCMS database user
• Authentication events to the admin panel from atypical source IPs preceding suspicious database activity

Detection Strategies

• Inspect web server and application logs for requests targeting the batchCope action with anomalous ids payloads
• Deploy a web application firewall rule that flags SQL injection signatures on requests to /admin/Video/* endpoints
• Enable database query logging and alert on syntactically unusual queries originating from the FoxCMS service account
• Correlate admin authentication events with subsequent batch operation requests to identify abuse of low-privilege accounts

Monitoring Recommendations

• Forward FoxCMS application and database logs to a centralized log analytics platform for retention and search
• Establish baselines for normal admin batch operation volume and alert on deviations
• Monitor outbound database connections for data exfiltration patterns following suspicious admin activity
• Track failed and successful logins to the admin panel and review accounts with batch operation privileges

How to Mitigate CVE-2025-7568

Immediate Actions Required

• Restrict access to the FoxCMS admin interface using IP allow-listing or VPN-only access until a vendor patch is available
• Audit all admin accounts and disable or rotate credentials for accounts that do not require batch operation privileges
• Place the application behind a web application firewall configured with SQL injection protection rules
• Review database logs for evidence of prior exploitation against the batchCope endpoint

Patch Information

No vendor patch is available at the time of writing. The vendor was contacted before disclosure but did not respond. Monitor the qianfox FoxCMS project references and the VulDB advisory for updates on a fixed release.

Workarounds

• Apply a virtual patch at the WAF layer to reject requests where the ids parameter contains non-numeric characters
• Modify the batchCope function in app/admin/controller/Video.php to validate that ids contains only digits and commas before query construction
• Replace direct string concatenation with parameterized queries or the framework's query builder bindings
• Limit the FoxCMS database account to the minimum privileges required for application function to reduce blast radius

# Example WAF rule concept for blocking non-numeric ids values
# Reject requests to batchCope where ids contains SQL metacharacters
