Mitigates 16 ATT&CK techniques, used by 8 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-3062 techniquesMissing Authentication for Critical FunctionA sensitive function requires no login at all; one of the most exploited flaws in edge devices.
- CWE-11881 techniquesInitialization of a Resource with an Insecure DefaultThe product ships insecure by default, and many installations never change it.
- CWE-1191 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-1201 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-1211 techniquesStack-based Buffer OverflowAn overflow on the stack can overwrite the return address and redirect the program to attacker code.
- CWE-1221 techniquesHeap-based Buffer OverflowAn overflow on the heap corrupts neighbouring objects, often turned into code execution.
- CWE-13211 techniquesImproperly Controlled Modification of Object Prototype Attributes ('Prototype Pollution')Input changes the base prototype of JavaScript objects, altering behaviour across the whole application.
- CWE-2501 techniquesExecution with Unnecessary PrivilegesSoftware runs with more privilege than it needs, so any flaw in it is a flaw with full power.
- CWE-2691 techniquesImproper Privilege ManagementPrivileges are assigned or dropped incorrectly, so a low-privileged foothold becomes administrator.
- CWE-2841 techniquesImproper Access ControlRestrictions on who can access a resource are missing or wrong.
