Weakness (CWE)
CWE-134: Use of Externally-Controlled Format String
The product uses a function that accepts a format string as an argument, but the format string originates from an external source.
How to prevent it (3 mitigations)
-
Requirements
Choose a language that is not subject to this flaw.
-
Implementation
Ensure that all format string functions are passed a static string which cannot be controlled by the user, and that the proper number of arguments are always sent to that function as well. If at all possible, use functions that do not support the %n operator in format strings. [REF-116] [REF-117]
-
Build and Compilation
Run compilers and linkers with high warning levels, since they may detect incorrect usage.
