Weaknesses
CWE · root cause- CWE-92DEPRECATED: Improper Sanitization of Custom Special CharactersThis entry has been deprecated. It originally came from PLOVER, which sometimes defined "other" and "miscellaneous" categories in order to satisfy exhaustiveness requirements for taxonomies. Within the context of CWE, the use of a more abstract entry is preferred in mapping situations. CWE-75 is a more appropriate mapping.
- CWE-119Improper Restriction of Operations within the Bounds of a Memory BufferThe product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
