◆ SeCaptureSidAndAttributesArray()

NTSTATUS NTAPI SeCaptureSidAndAttributesArray ( _In_ PSID_AND_ATTRIBUTES  SrcSidAndAttributes,
_In_ ULONG  AttributeCount,
_In_ KPROCESSOR_MODE  PreviousMode,
_In_opt_ PVOID  AllocatedMem,
_In_ ULONG  AllocatedLength,
_In_ POOL_TYPE  PoolType,
_In_ BOOLEAN  CaptureIfKernel,
_Out_ PSID_AND_ATTRIBUTES CapturedSidAndAttributes,
_Out_ PULONG  ResultLength 
)

Captures a SID with attributes.

Parameters
[in]SrcSidAndAttributesSource of the SID with attributes to be captured.
[in]AttributeCountThe number count of attributes, in total.
[in]PreviousModeProcessor access level mode.
[in]AllocatedMemThe allocated memory buffer for the captured SID. If the caller supplies no allocated block of memory then the function will allocate some buffer block of memory for the captured SID automatically.
[in]AllocatedLengthThe length of the buffer that points to the allocated memory, in bytes.
[in]PoolTypeThe pool type for the captured SID and attributes to assign.
[in]CaptureIfKernelIf set to TRUE, the capturing is done within the kernel. Otherwise the capturing is done in a kernel mode driver.
[out]CapturedSidAndAttributesThe captured SID and attributes.
[out]ResultLengthThe length of the captured SID and attributes, in bytes.
Returns
Returns STATUS_SUCCESS if SID and attributes capturing has been completed successfully. STATUS_INVALID_PARAMETER is returned if the count of attributes exceeds the maximum threshold that the kernel can permit, with the purpose of avoiding integer overflows. STATUS_INSUFFICIENT_RESOURCES is returned if memory pool allocation for the captured SID has failed. STATUS_BUFFER_TOO_SMALL is returned if the length of the allocated buffer is less than the required size. STATUS_INVALID_SID is returned if a SID doesn't meet certain requirements to be considered a valid SID by the security manager. A failure NTSTATUS code is returned otherwise.
Remarks
A security identifier (SID) is a variable-length data structure that can change in size over time, depending on the factors that influence this effect in question. An attacker can take advantage of this fact and can potentially modify certain properties of a SID making it different in size than it was originally before. This is what we'd call, a TOCTOU vulnerability.

For this reason, the logic of copying the SIDs and their attributes into a new buffer goes like this: first, allocate a buffer array that just holds the lengths and subauthority count of each SID. Such information is copied in the first loop. Then in a second loop, iterate over the array with SID provided and copy them into the final array. The moment we're doing this, validate the lengths of each SID basing upon the captured lengths we've got before. In this way we ensure that the SIDs have remained intact. The validation checks are done in user mode as a general rule that we just cannot trust UM and whatever data is coming from it.

◆ SepCaptureSid()

NTSTATUS NTAPI SepCaptureSid ( _In_ PSID  InputSid,
_In_ KPROCESSOR_MODE  AccessMode,
_In_ POOL_TYPE  PoolType,
_In_ BOOLEAN  CaptureIfKernel,
_Out_ PSID CapturedSid 
)

Captures a SID.

Parameters
[in]InputSidA valid security identifier to be captured.
[in]AccessModeProcessor level access mode.
[in]PoolTypePool memory type for the captured SID to assign upon allocation.
[in]CaptureIfKernelIf set to TRUE, the capturing is done within the kernel. Otherwise the capturing is done in a kernel mode driver.
[out]CapturedSidThe captured security identifier, returned to the caller.
Returns
Returns STATUS_SUCCESS if the SID was captured. STATUS_INSUFFICIENT_RESOURCES is returned if memory pool allocation for the captured SID has failed.
