CVE-2026-33867

Description

### Summary AVideo allows content owners to password-protect individual videos. The video password is stored in the database in **plaintext** - no hashing, salting, or encryption is applied. If an attacker gains read access to the database (via SQL injection, a database backup, or misconfigured access controls), they obtain all video passwords in cleartext. ### Details **File:** `objects/video.php` **Vulnerable setter:** ```php public function setVideo_password($video_password) { AVideoPlugin::onVideoSetVideo_password($this->id, $this->video_password, $video_password); $this->video_password = trim($video_password); } ``` **Vulnerable getter:** ```php public function getVideo_password() { if (empty($this->video_password)) { return ''; } return trim($this->video_password); } ``` The value assigned to `$this->video_password` is only `trim()`-ed before being persisted to the database column `video_password` in the `videos` table. There is no call to any hashing function (e.g., `password_hash()`, `sha256`, or similar). When a visitor enters a password to access a protected video, the comparison is done directly against the stored plaintext: ```php // Comparison at access check: if ($video->getVideo_password() === $_POST['password']) { ... } ``` This means: 1. Any database read (SQL injection, backup leak, hosting panel access) exposes all video passwords as cleartext. 2. Video passwords are often reused by users across other services, making this a credential harvesting risk. 3. The plaintext value is also present in application memory and any query logs. ### PoC 1. Set a password on any video via the AVideo admin/creator UI. 2. Query the database: `SELECT clean_title, video_password FROM videos WHERE video_password != '';` 3. All video passwords are returned in plaintext - no cracking required. Alternatively, exploit any of the SQL injection vulnerabilities already reported in this repository to extract the `video_password` column directly. ### Impact - **Type:** Cleartext Storage of Sensitive Information (CWE-312) - **Severity:** High - **Authentication required:** No - any database read access (including via SQL injection by unauthenticated users) exposes all passwords - **Impact:** Full exposure of all video access passwords; credential reuse attacks against users who share passwords across services - **Fix:** Hash video passwords on write using `password_hash($video_password, PASSWORD_BCRYPT)` and verify on read using `password_verify($_POST['password'], $stored_hash)`
