SI-2 Flaw Remediation
Mitigates 84 ATT&CK techniques, used by 12 threats in this month's news.
Why it matters this month
Threats in SecurityTabs news using techniques this control mitigates.
Weaknesses it helps against
Through the techniques typically used to exploit them (CTID, CISA KEV).
- CWE-1198 techniquesImproper 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-1208 techniquesBuffer 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-1218 techniquesStack-based Buffer OverflowAn overflow on the stack can overwrite the return address and redirect the program to attacker code.
- CWE-1228 techniquesHeap-based Buffer OverflowAn overflow on the heap corrupts neighbouring objects, often turned into code execution.
- CWE-207 techniquesImproper Input ValidationInput isn't checked against what the program expects; the umbrella cause behind many specific flaws.
- CWE-777 techniquesImproper 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-787 techniquesImproper 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-1256 techniquesOut-of-bounds ReadCode reads beyond a buffer, leaking secrets such as keys or memory addresses that defeat other defences.
- CWE-4166 techniquesUse After FreeThe program keeps using memory after releasing it, so an attacker who controls what lands there next can hijack execution.
- CWE-7876 techniquesOut-of-bounds WriteData is written outside the memory it belongs to; the most common root cause of exploited memory bugs.
