SI-5 Security Alerts, Advisories, and Directives
Mitigates 4 ATT&CK techniques, used by 5 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-222 techniquesImproper Limitation of a Pathname to a Restricted Directory ('Path Traversal')Sequences like ../ in a file path escape the intended folder, exposing or overwriting other files.
- CWE-232 techniquesRelative Path TraversalRelative ../ segments in input climb out of the allowed directory.
- CWE-2842 techniquesImproper Access ControlRestrictions on who can access a resource are missing or wrong.
- CWE-2852 techniquesImproper AuthorizationThe system checks who you are but not whether you're allowed to do what you're asking.
- CWE-362 techniquesAbsolute Path TraversalAn absolute path in input points straight at a file outside the allowed directory.
- CWE-6392 techniquesAuthorization Bypass Through User-Controlled KeyChanging an id in a request (an IDOR) returns another user's data.
- CWE-8622 techniquesMissing AuthorizationNo permission check is made before the action, so any logged-in user can perform it.
- CWE-8632 techniquesIncorrect AuthorizationA permission check exists but is wrong, letting users act beyond their role.
- 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.
