For example, the attacker might replace a table definition with a view. Or the attacker might add triggers to tables or views, or add new CHECK constraints or generated columns or indexes with expressions in the index list or in the WHERE clause. If the added features invoke SQL functions or virtual tables with side effects, that might cause harm to the system if run by a high-privilege victim. Or, the added features might exfiltrate information if the database is read by a high-privilege victim. The changes in this branch strive to make it easier for high-privilege applications to safely read SQLite database files that might have been maliciously corrupted by an attacker. ## Overview of changes in [new-security-options](/timeline?r=new-security-options) The basic idea is to tag every SQL function and virtual table with one of three risk levels: 1. Innocuous 2. Normal 3. Direct-Only Innocuous functions/vtabs are safe and can be used at any time. Direct-only elements, in contrast, might have cause side-effects and should only be used from top-level SQL, not from within triggers or views nor in elements of the schema such as CHECK constraint, DEFAULT values, generated columns, index expressions, or in the WHERE clause of a partial index that are potentially under the control of an attacker. Normal elements behave like Innocuous if TRUSTED\_SCHEMA=on and behave like direct-only if TRUSTED\_SCHEMA=off. Application-defined functions and virtual tables go in as Normal unless the application takes deliberate steps to change the risk level. For backwards compatibility, the default is TRUSTED\_SCHEMA=on. Documentation will be updated to recommend applications turn TRUSTED\_SCHEMA to off. An innocuous function or virtual table is one that can only read content from the database file in which it resides, and can only alter the database in which it resides. Most SQL functions are innocuous. For example, there is no harm in an attacker running the abs() function. Direct-only elements that have side-effects that go outside the database file in which it lives, or return information from outside of the database file. Examples of direct-only elements include: 1. The fts3\_tokenizer() function 2. The writefile() function 3. The readfile() function 4. The zipvfs virtual table 5. The csv virtual table We do not want an attacker to be able to add these kinds of things to the database schema and possibly trick a high-privilege application from performing any of these actions. Therefore, functions and vtabs with side-effects are marked as Direct-Only. Legacy applications might add other risky functions or vtabs. Those will go in as "Normal" by default. For optimal security, we want those risky app-defined functions and vtabs to be direct-only, but making that the default might break some legacy applications. Hence, all app-defined functions and vtabs go in as Normal, but the application can switch them over to "Direct-Only" behavior using a single pragma. The restrictions on the use of functions and virtual tables do not apply to TEMP. A TEMP VIEW or a TEMP TRIGGER can use any valid SQL function or virtual table. The idea is that TEMP views and triggers must be directly created by the application and are thus under the control of the application. TEMP views and triggers cannot be created by an attacker who corrupts the schema of a persistent database file. Hence TEMP views and triggers are safe. ## Specific changes 1. New sqlite3\_db\_config() option SQLITE\_DBCONFIG\_TRUSTED\_SCHEMA for turning TRUSTED\_SCHEMA on and off. It defaults to ON. 2. Compile-time option -DSQLITE\_TRUSTED\_SCHEMA=0 causes the default TRUSTED\_SCHEMA setting to be off. 3. New pragma "PRAGMA trusted\_schema=(ON\|OFF);". This provides access to the TRUSTED_SCHEMA setting for application coded using scripting languages or other secondary languages where they are unable to make calls to sqlite3\_db\_config(). 4. New options for the "enc" parameter to sqlite3\_create\_function() and its kin: <ol type="a"> <li> _SQLITE\_INNOCUOUS_ → tags the new functions as Innocuous <li> _SQLITE\_DIRECTONLY_ → tags the new functions as Direct-Only </ol> 5. New options to sqlite3\_vtab\_config(): <ol type="a"> <li> _SQLITE\_VTAB\_INNOCUOUS_ → tags the vtab as Innocuous <li> _SQLITE\_VTAB\_DIRECTONLY_ → tags the vtab as Direct-Only </ol> 6. Change many of the functions and virtual tables in the SQLite source tree to use one of the tags above. 7. Enhanced PRAGMA function\_list and virtual-table "pragma\_function\_list" with additional columns. The columns now are: <ul> <li> _name_ → Name of the function <li> _builtin_ → 1 for built-in functions. 0 otherwise. <li> _type_ → 's'=Scalar, 'a'=Aggregate, 'w'=Window <li> _enc_ → 'utf8', 'utf16le', or 'utf16be' <li> _narg_ → number of argument <li> _flags_ → Bitmask of SQLITE\_INNOCUOUS, SQLITE\_DIRECTONLY, SQLITE\_DETERMINISTIC, SQLITE\_SUBTYPE, and SQLITE\_FUNC\_INTERNAL flags. </ul> <p>The last four columns are new. 8. The function\_list PRAGMA now also shows all entries for each function. So, for example, if a function can take either 2 or 3 arguments, there are separate rows for the 2-argument and 3-argument versions of the function. ## Additional Notes The function_list enhancements allow the application to query the set of SQL functions that meet various criteria. For example, to see all SQL functions that are never allowed to be used in the schema or in trigger or views: ~~~ SELECT DISTINCT name FROM pragma_function_list WHERE (flags & 0x80000)!=0 ORDER BY name; ~~~ Doing the same is not possible for virtual tables, as a virtual table might be Innocuous, Normal, or Direct-Only depending on the arguments passed into the xConnect method. |

Functions must ** be deterministic in order to be used in certain contexts such as ** [CHECK constraints] or [generated columns]. SQLite might also optimize ** deterministic functions by factoring them out of inner loops. ** ** The SQLITE_INNOCUOUS flag means that the new function is unlikely ** to cause problems even if misused. An innocuous function should have ** no side effects and consume few resources. The [abs|abs() function] ** is an example of an innocuous function. ** The [load_extension() SQL function] is not innocuous because of its ** side effects. Some heightened security settings ** ([SQLITE_DBCONFIG_UNSAFE_FUNC_IN_VIEW]) ** disable the use of SQLlfunctions inside views and triggers unless ** the function is tagged with SQLITE_INNOCUOUS. Most built-in functions ** are innocuous. Developers are advised to avoid using the ** SQLITE_INNOCUOUS flag for application-defined functions unless the ** function is specifically intended for use inside of views and triggers. ** ** The SQLITE_DIRECTONLY flag means that the function may only be invoked ** from top-level SQL, and cannot be used in VIEWs or TRIGGERs. This is ** a security feature which is recommended for all ** [application-defined SQL functions] that have side-effects. This flag ** prevents an attacker from adding triggers and views to a schema then ** tricking a high-privilege application into causing unintended side-effects ** while performing ordinary queries. ** ** The SQLITE_SUBTYPE flag indicates to SQLite that a function may call ** [sqlite3_value_subtype()] to inspect the sub-types of its arguments. ** Specifying this flag makes no difference for scalar or aggregate user ** functions. However, if it is not specified for a user-defined window ** function, then any sub-types belonging to arguments passed to the window ** function may be discarded before the window function is called (i.e. ** sqlite3_value_subtype() will always return 0). */ #define SQLITE_DETERMINISTIC 0x000000800 #define SQLITE_DIRECTONLY 0x000080000 #define SQLITE_SUBTYPE 0x000100000 #define SQLITE_INNOCUOUS 0x000200000 /* ** CAPI3REF: Deprecated Functions ** DEPRECATED ** ** These functions are [deprecated].
