HIGH 8.8

DescriptionGitHub Advisory

AVideo is a video-sharing Platform. Versions prior to 8.0 contain a SQL Injection vulnerability in the getSqlFromPost() method of Object.php. The $_POST['sort'] array keys are used directly as SQL column identifiers inside an ORDER BY clause. Although real_escape_string() was applied, it only escapes string-context characters (quotes, null bytes) and provides no protection for SQL identifiers - making it entirely ineffective here. This issue has been fixed in version 8.0. To workaround this issue without upgrading, operators can apply a WAF rule to block POST requests where any sort[*] key contains characters outside [A-Za-z0-9_]. Alternatively, restrict access to the queue view (queue.json.php, index.php) to trusted IP ranges only.

AnalysisAI

Unauthenticated SQL injection in AVideo versions before 8.0 allows authenticated attackers to manipulate database queries through unsanitized sort parameters in POST requests, potentially leading to unauthorized data access or modification. The vulnerability stems from improper use of real_escape_string() on SQL identifiers rather than string literals, rendering the escaping mechanism ineffective. Affected organizations should upgrade to version 8.0 or implement WAF rules restricting sort parameter characters to alphanumeric and underscore values.

Technical ContextAI

This vulnerability affects AVideo-Encoder (CPE data indicates cpe:2.3:a:avideo:avideo-encoder versions below 8.0), a PHP-based video encoding and sharing platform. The root cause is CWE-89 (SQL Injection) where the application incorrectly relies on real_escape_string() to sanitize SQL identifiers in an ORDER BY clause. The real_escape_string() function only escapes string-context characters like quotes and null bytes, but provides no protection when user input is used directly as column names or SQL identifiers outside of quoted strings. The vulnerable code path is in the Object.php file's getSqlFromPost() method, which processes the sort parameter from POST requests and constructs dynamic SQL queries. This represents a fundamental misunderstanding of SQL injection prevention, where identifier context requires allowlisting or proper quoting mechanisms rather than string escaping.

RemediationAI

Upgrade AVideo-Encoder to version 8.0 or later, which contains the fix as documented in the GitHub commit at https://github.com/WWBN/AVideo-Encoder/commit/d1c8a17ac88b5e27da9dfb7a230bbaf54aa53124 and detailed in the security advisory at https://github.com/WWBN/AVideo-Encoder/security/advisories/GHSA-5qvj-5h75-27pj. For environments where immediate upgrading is not feasible, implement a Web Application Firewall (WAF) rule to block POST requests where any sort parameter key contains characters outside the range [A-Za-z0-9_], effectively restricting sort keys to valid SQL identifier characters. As an additional mitigation layer, restrict access to the vulnerable endpoints (queue.json.php and index.php) to trusted IP ranges using network-level access controls or reverse proxy rules, reducing the attack surface to only trusted authenticated users.
