NSA Issues Guidance for Combating Web Shell Malware

The US intelligence agency teamed up with Australian Signals Directorate in newly released information on how to protect Web servers from the malware.

Web shell malware, which executes arbitrary instructions on a targeted Web server, is a large and growing cybersecurity problem — and now government intelligence agencies are releasing guidance on how to defend against it. The US National Security Agency (NSA) and the Australian Signals Directorate (ASD) joined forces this week to issue a Cybersecurity Information Sheet on how to detect and mitigate this form of malware.

The sheet includes information on detecting Web shells, such as tips on using known-good comparison, in which a file on the Web server is compared to a "known good" version of the file stored in a secure location.

NSA and ASD also provide instructions on mitigating the threat through the use of IDS/IPS technology, Web flow detection, and file-integrity monitoring to quickly detect files that have been modified without administrator permission.

CVE-2020-15208
PUBLISHED: 2020-09-25
In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, when determining the common dimension size of two tensors, TFLite uses a `DCHECK` which is no-op outside of debug compilation modes. Since the function always returns the dimension of the first tensor, malicious attackers can ...
CVE-2020-15209
PUBLISHED: 2020-09-25
In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, a crafted TFLite model can force a node to have as input a tensor backed by a `nullptr` buffer. This can be achieved by changing a buffer index in the flatbuffer serialization to convert a read-only tensor to a read-write one....
CVE-2020-15210
PUBLISHED: 2020-09-25
In tensorflow-lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, if a TFLite saved model uses the same tensor as both input and output of an operator, then, depending on the operator, we can observe a segmentation fault or just memory corruption. We have patched the issue in d58c96946b and ...
CVE-2020-15211
PUBLISHED: 2020-09-25
In TensorFlow Lite before versions 1.15.4, 2.0.3, 2.1.2, 2.2.1 and 2.3.1, saved models in the flatbuffer format use a double indexing scheme: a model has a set of subgraphs, each subgraph has a set of operators and each operator has a set of input/output tensors. The flatbuffer format uses indices f...
CVE-2020-15212
PUBLISHED: 2020-09-25
In TensorFlow Lite before versions 2.2.1 and 2.3.1, models using segment sum can trigger writes outside of bounds of heap allocated buffers by inserting negative elements in the segment ids tensor. Users having access to `segment_ids_data` can alter `output_index` and then write to outside of `outpu...
