CVE-2026-33767
|
| Summary | AVideo has SQL Injection via Partial Prepared Statement — videos_id Concatenated Directly into Query ### Summary In `objects/like.php`, the `getLike()` method constructs a SQL query using a prepared statement placeholder (`?`) for `users_id` but directly concatenates `$this->videos_id` into the query string without parameterization. An attacker who can control the `videos_id` value (via a crafted request) can inject arbitrary SQL, bypassing the partial prepared-statement protection. ### Details **File:** `objects/like.php` **Vulnerable code:** ```php $sql = "SELECT * FROM likes WHERE users_id = ? AND videos_id = ".$this->videos_id." LIMIT 1;"; $res = sqlDAL::readSql($sql, "i", [$this->users_id]); ``` The query mixes a parameterized placeholder for `users_id` with raw string concatenation for `videos_id`. The `$this->videos_id` value originates from user-supplied request input (typically a POST/GET parameter identifying the video being liked/disliked) and is not cast to integer or validated before being embedded in the SQL string. All other queries in the same file correctly use `?` placeholders for both columns: ```php // Correct pattern used elsewhere: $sql = "SELECT count(*) as total FROM likes WHERE videos_id = ? AND like = 1"; ``` The inconsistency means any attacker who can submit a like/dislike action with a crafted `videos_id` can inject SQL. Since like/dislike actions are typically available to any authenticated user, the attack surface is broad. ### PoC An attacker sends a like request with an injected `videos_id`: ``` POST /objects/likeAjax.json.php videos_id=1 UNION SELECT user,password,3,4,5,6,7,8 FROM users-- - ``` This causes the backend to execute: ```sql SELECT * FROM likes WHERE users_id = 1 AND videos_id = 1 UNION SELECT user,password,3,4,5,6,7,8 FROM users-- - LIMIT 1; ``` Result: full database read — user credentials, emails, private content, and any other data accessible to the MySQL user. ### Impact - **Severity:** High - **Authentication required:** Yes (must be logged in to like a video), but all registered users qualify - **Impact:** Full database read via UNION-based injection; potential for data modification or deletion depending on DB user privileges - **Fix:** Replace the concatenation with a second `?` placeholder and pass `$this->videos_id` as a bound integer parameter |
