Blind SQL Injection in ClipBucket Video Sharing Platform

Executive Summary

This vulnerability exists in ClipBucket v5, an open source video sharing platform. Before version 5.5.3 - #129, the actions/progress_video.php endpoint is vulnerable to a blind SQL injection attack. An unauthenticated user can exploit the 'ids' parameter to execute arbitrary SQL queries on the database.

This allows the attacker to exfiltrate sensitive data from the database without authentication.

The vulnerability has been fixed in version 5.5.3 - #129.

Impact Analysis

This vulnerability can have severe impacts because it allows unauthenticated attackers to execute SQL queries and extract sensitive data from the database.

• Compromise of confidential user data stored in the database.
• Potential full compromise of the application’s data integrity and availability.
• High risk of data breaches leading to loss of trust and possible legal consequences.

The CVSS score of 9.8 indicates a critical severity with high impact on confidentiality, integrity, and availability.

Mitigation Strategies

To mitigate this vulnerability, you should upgrade ClipBucket to version 5.5.3 - #129 or later, where the blind SQL injection issue in the actions/progress_video.php endpoint has been patched.

Compliance Impact

The vulnerability in ClipBucket v5 prior to version 5.5.3 allows unauthenticated users to perform blind SQL injection via the ids parameter, potentially leading to the exfiltration of sensitive data.

Such unauthorized access and data exfiltration could result in non-compliance with data protection regulations like GDPR and HIPAA, which require safeguarding sensitive personal and health information against unauthorized access and breaches.

Therefore, if exploited, this vulnerability could lead to violations of these standards due to compromised confidentiality, integrity, and availability of sensitive data.

Detection Guidance

This vulnerability can be detected by testing the `progress_video.php` endpoint of ClipBucket v5 for blind SQL injection via the `ids` parameter. Since it is a blind SQL injection, detection involves sending crafted payloads to the `ids` parameter and observing differences in the application's behavior or response times to infer if the parameter is vulnerable.

A common approach is to use automated tools or manual commands to send SQL injection payloads and analyze responses. For example, using curl or sqlmap to test the endpoint:

• Using curl to send a test payload: curl -v "http://target/progress_video.php?ids=1' AND SLEEP(5)--"
• Using sqlmap to test and exploit the vulnerability: sqlmap -u "http://target/progress_video.php?ids=1" --batch --technique=B --dbs

These commands attempt to detect blind SQL injection by causing delays or extracting database information. If the server response is delayed or data is retrieved, it indicates the presence of the vulnerability.
