Weaknesses that lead here
Classes of exploited vulnerability that CTID maps to this technique.
- CWE-4162 KEV CVEsUse After FreeThe program keeps using memory after releasing it, so an attacker who controls what lands there next can hijack execution.
- CWE-772 KEV CVEsImproper Neutralization of Special Elements used in a Command ('Command Injection')Input is pasted into a command without escaping, so attackers append commands of their own.
- CWE-782 KEV CVEsImproper Neutralization of Special Elements used in an OS Command ('OS Command Injection')Input reaches an operating-system shell, letting an attacker run any command the service can.
- CWE-1191 KEV CVEImproper Restriction of Operations within the Bounds of a Memory BufferCode reads or writes past the end of a buffer, the root of most classic memory-corruption exploits.
- CWE-1201 KEV CVEBuffer Copy without Checking Size of Input ('Classic Buffer Overflow')Input is copied into a fixed-size buffer without checking its length, overwriting whatever follows.
- CWE-1211 KEV CVEStack-based Buffer OverflowAn overflow on the stack can overwrite the return address and redirect the program to attacker code.
- CWE-1221 KEV CVEHeap-based Buffer OverflowAn overflow on the heap corrupts neighbouring objects, often turned into code execution.
- CWE-13361 KEV CVEImproper Neutralization of Special Elements Used in a Template EngineInput is rendered as a template, so template syntax in it runs on the server.
