CVE-2025-8382: Hotel Reservation System SQLi Vulnerability

CVE-2025-8382 Overview

CVE-2025-8382 is a SQL injection vulnerability in Campcodes Online Hotel Reservation System 1.0. The flaw resides in the /admin/edit_room.php script, where the room_id parameter is passed to a database query without proper sanitization. An authenticated remote attacker can manipulate this parameter to inject arbitrary SQL statements. The exploit details have been disclosed publicly, increasing the likelihood of opportunistic attacks against exposed installations. The vulnerability is tracked under [CWE-74] (Improper Neutralization of Special Elements in Output).

Critical Impact

Remote attackers with low-privilege access can inject SQL statements through the room_id parameter to read, modify, or delete reservation data.

Technical Details for CVE-2025-8382

Vulnerability Analysis

The vulnerability exists in the administrative interface of Campcodes Online Hotel Reservation System 1.0. The /admin/edit_room.php endpoint accepts a room_id request parameter and concatenates it directly into a SQL query. Because the application does not validate, sanitize, or parameterize the input, an attacker can break out of the original query context and append arbitrary SQL clauses.

Successful exploitation grants the attacker the ability to read sensitive reservation data, modify room records, or enumerate the underlying database schema. The flaw is reachable over the network and requires only low-level authentication to the admin panel. Public disclosure of the exploit on third-party trackers raises the risk of automated scanning and exploitation attempts.

Root Cause

The root cause is the absence of prepared statements or input validation when handling the room_id parameter in edit_room.php. The application uses string concatenation to build SQL queries, allowing untrusted input to be interpreted as code. This is a textbook case of [CWE-74] injection, where input is not properly neutralized before being passed to a downstream interpreter.

Attack Vector

An attacker with access to the admin interface sends a crafted HTTP request to /admin/edit_room.php with a malicious room_id value. Typical payloads include classic union-based, boolean-based, or time-based blind SQL injection patterns. The vulnerability is exploitable remotely without user interaction beyond submitting the request. Refer to the GitHub Issue Discussion and VulDB #318360 for technical write-ups of the issue.

Detection Methods for CVE-2025-8382

Indicators of Compromise

• HTTP requests to /admin/edit_room.php containing SQL metacharacters such as ', --, UNION, SLEEP(, or OR 1=1 in the room_id parameter.
• Unusual database query patterns or unexpected SELECT, UPDATE, or DROP statements originating from the application user.
• Anomalous response time spikes consistent with time-based blind SQL injection probing.

Detection Strategies

• Deploy web application firewall (WAF) rules that inspect query and POST parameters for SQL injection signatures targeting room_id.
• Enable verbose database query logging and alert on syntax errors or queries containing tautologies on the rooms table.
• Correlate web server access logs with database logs to identify requests that produced abnormal query payloads.

Monitoring Recommendations

• Monitor authentication and session logs for /admin/ access from unexpected IP addresses or geographies.
• Track query volume and error rates against the reservation database for sudden deviations from baseline.
• Forward web, application, and database telemetry to a centralized SIEM to enable cross-source correlation and historical hunting.

How to Mitigate CVE-2025-8382

Immediate Actions Required

• Restrict access to /admin/edit_room.php to trusted IP ranges or via VPN until a fix is applied.
• Audit application and database logs for prior exploitation attempts referencing the room_id parameter.
• Rotate database credentials and admin passwords if compromise is suspected.

Patch Information

No vendor patch is currently referenced in the NVD entry for CVE-2025-8382. Operators should monitor the CampCodes website for updates and consider replacing the affected component with a maintained alternative if no fix is released.

Workarounds

• Apply WAF rules that block SQL metacharacters in the room_id parameter on /admin/edit_room.php.
• Modify the source code to use parameterized queries or prepared statements for all database interactions involving user input.
• Enforce least-privilege database accounts so the web application cannot execute administrative SQL commands such as DROP or GRANT.

# Example ModSecurity rule to block SQLi attempts against the vulnerable endpoint
