  "details": "## Summary\n\nThe MyList configuration feature in Admidio allows authenticated users to define custom list column layouts. User-supplied column names, sort directions, and filter conditions are stored in the `adm_list_columns` table via prepared statements (safe storage), but are later read back and interpolated directly into dynamically constructed SQL queries without sanitization or parameterization. This is a classic second-order SQL injection: safe write, unsafe read.\n\nAn attacker can inject arbitrary SQL through these stored values to read, modify, or delete any data in the database, potentially achieving full database compromise.\n\n## Details\n\n### Step 1: Storing the Payload (Safe Write)\n\nIn `modules/groups-roles/mylist_function.php` (lines 89-115), user-supplied POST array values for column names, sort directions, and filter conditions are accepted. The only validation on column values is a prefix check (must start with `usr_` or `mem_`). Sort and condition values have no validation at all. These values are stored in the database via `ListConfiguration::addColumn()` which calls `Entity::save()` using prepared statements -- so the INSERT/UPDATE is safe.\n\nKey source file references:\n- `D:\\bugcrowd\\admidio\\repo\\modules\\groups-roles\\mylist_function.php` lines 89-115\n- `D:\\bugcrowd\\admidio\\repo\\src\\Roles\\Entity\\ListConfiguration.php` lines 106-116\n\n### Step 2: Triggering the Payload (Unsafe Read)\n\nWhen the list is viewed (via `lists_show.php`), `ListConfiguration::getSql()` reads the stored values and interpolates them directly into SQL in four locations:\n\n**Injection Point 1 -- lsc_special_field in SELECT clause:**\nFile `D:\\bugcrowd\\admidio\\repo\\src\\Roles\\Entity\\ListConfiguration.php` lines 739-770.\nThe `lsc_special_field` value is read from the database and used as a column name in the SELECT clause. Only three values (`mem_duration`, `mem_begin`, `mem_end`) get special handling; all others fall through to the `default` case where the raw value is used directly as both `$dbColumnName` and `$sqlColumnName`, then interpolated into the SQL as `$dbColumnName AS $sqlColumnName`.\n\n**Injection Point 2 -- lsc_sort in ORDER BY clause:**\nFile `D:\\bugcrowd\\admidio\\repo\\src\\Roles\\Entity\\ListConfiguration.php` lines 790-792.\nThe `lsc_sort` value is appended directly after the column name in the ORDER BY clause.\n\n**Injection Point 3 -- lsc_special_field in search conditions:**\nFile `D:\\bugcrowd\\admidio\\repo\\src\\Roles\\Entity\\ListConfiguration.php` lines 611-621.\nThe `lsc_special_field` value is interpolated into COALESCE() expressions used in search WHERE conditions.\n\n**Injection Point 4 -- lsc_filter via ConditionParser:**\nFile `D:\\bugcrowd\\admidio\\repo\\src\\Roles\\ValueObject\\ConditionParser.php` line 347.\nThe ConditionParser appends raw characters from the stored filter value to the SQL string. A single quote can break out of the SQL string context.\n\n### Root Cause\n\nThe `addColumn()` method and `mylist_function.php` accept arbitrary strings for column names, sort directions, and filter conditions. The only gate for column names is a prefix check (`usr_` or `mem_`), which is trivially satisfied by an attacker (e.g., `usr_id) UNION SELECT ...`). No allowlist of valid column names exists. No server-side validation of sort values exists (should only allow ASC/DESC/empty). The frontend `\u003cselect\u003e` element only offers ASC/DESC, but this is trivially bypassed by POSTing arbitrary values.\n\n## PoC\n\n**Prerequisites:** Logged-in user with list edit permission (default: all logged-in users).\n\n**Step 1: Save a list config with SQL injection in lsc_special_field**\n\n```\ncurl -X POST \"https://TARGET/adm_program/modules/groups-roles/mylist_function.php?mode=save_temporary\" \\\n  -H \"Cookie: ADMIDIO_SESSION_ID=\u003csession\u003e\" \\\n  -d \"adm_csrf_token=\u003ccsrf_token\u003e\" \\\n  -d \"column[]=usr_login_name\" \\\n  -d \"column[]=usr_id FROM adm_users)--\" \\\n  -d \"sort[]=\" \\\n  -d \"sort[]=\" \\\n  -d \"condition[]=\" \\\n  -d \"condition[]=\" \\\n  -d \"sel_roles[]=\u003cvalid_role_uuid\u003e\"\n```\n\nThe second column value `usr_id FROM adm_users)--` starts with `usr_` so it passes the prefix check. When read back in `getSql()`, it is interpolated directly as a column expression in the SQL SELECT clause.\n\n**Step 2: Sort-based injection (simpler, no prefix check needed)**\n\n```\ncurl -X POST \"https://TARGET/adm_program/modules/groups-roles/mylist_function.php?mode=save_temporary\" \\\n  -H \"Cookie: ADMIDIO_SESSION_ID=\u003csession\u003e\" \\\n  -d \"adm_csrf_token=\u003ccsrf_token\u003e\" \\\n  -d \"column[]=usr_login_name\" \\\n  -d \"sort[]=ASC,(SELECT+CASE+WHEN+(1=1)+THEN+1+ELSE+1/0+END)\" \\\n  -d \"condition[]=\" \\\n  -d \"sel_roles[]=\u003cvalid_role_uuid\u003e\"\n```\n\nThis injects into the ORDER BY clause. The sort value has zero server-side validation.\n\n**Step 3:** The `save_temporary` mode automatically redirects to `lists_show.php` which calls `ListConfiguration::getSql()`, executing the injected SQL.\n\n## Impact\n\n- **Data Exfiltration:** An attacker can extract any data from the database including password hashes, email addresses, personal data of all members, and application configuration.\n- **Data Modification:** With stacked queries (supported by MySQL with PDO), the attacker can modify or delete data.\n- **Privilege Escalation:** Password hashes can be extracted and cracked, or admin accounts can be directly modified.\n- **Full Database Compromise:** The entire database is accessible through this vulnerability.\n\nThe attack requires authentication and CSRF token, but:\n1. Any logged-in user has this permission by default (when `groups_roles_edit_lists = 1`).\n2. The CSRF token is available in the same session.\n3. The injected payload persists in the database and triggers every time anyone views the list.\n\n## Recommended Fix\n\n### Fix 1: Allowlist for lsc_special_field\n\nAdd a strict allowlist of valid special field names before calling `addColumn()` in `mylist_function.php`. The list should match exactly the field names supported in `getSql()` and the JavaScript on `mylist.php`.\n\n### Fix 2: Validate lsc_sort values\n\nIn `ListConfiguration::addColumn()`, validate that the sort parameter is one of ASC, DESC, or empty string before storing it.\n\n### Fix 3: Defense-in-depth validation in ListConfiguration::getSql()\n\nAlso validate the `lsc_special_field` value against an allowlist in `getSql()` before interpolating it into the SQL string. This protects against payloads already stored in the database.\n\n### Fix 4: Escape filter values in ConditionParser\n\nUse parameterized queries or at minimum escape single quotes in `ConditionParser::makeSqlStatement()`.",
