Detailed Description
Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Easy network (Easy Mesh) is a networking authentication object for a plurality of wireless devices, which is proposed by the wireless fidelity (WiFi) alliance, and a plurality of wireless access points supporting the standard can construct a multi-node and wide-coverage wireless local area network.
Because Easy Mesh is an emerging technology, no vulnerability mining tool and method aiming at Easy Mesh exists at present.
A data Packet in the Easy Mesh network control stage is generally processed by one network node in the Mesh networking, and the network node in the Mesh networking may not be a specific device, but one device may also include a plurality of network nodes, so that when an automatic test is performed, the running state of the network node cannot be detected in a traditional serial port detection or Internet Packet explorer (ping) Packet sending mode, and abnormal monitoring during the test cannot be realized, so that the automatic test cannot be normally realized.
The embodiment of the application provides a testing method, a testing device, an electronic device and a computer-readable storage medium, which aim to solve at least one of the above technical problems in the prior art.
Fig. 1 shows a schematic flowchart of a testing method provided by an embodiment of the present disclosure, and as shown in fig. 1, the method mainly includes:
step S110: sending the variant data packet to a target node, and enabling the target node to process the variant data packet;
step S120: the test result is determined by sending a topology query message to the target node.
The variant packet is a packet for fuzz testing after variant processing, and may be, for example, a packet in an Easy Mesh network control stage after variant processing.
The target node is configured to process the variant data packet after receiving the variant data packet, and the target node may not be a specific device but be a logical entity, which may be separately deployed in a device or may be deployed in a device together with other target nodes. As an example, the target node may be a network node in a Mesh networking.
The topology query message is used for querying the topology information of the target node.
In the embodiment of the disclosure, the operation state of the target node can be determined by sending the topology query message to the target node, and the operation state of the target node can reflect the test result.
According to the method provided by the embodiment of the disclosure, the variant data packet is sent to the target node, so that the target node processes the variant data packet, and the test result is determined by sending the topology query message to the target node. According to the scheme, the operation state of the target node is determined by sending the topology query message to the target node, so that the test result is judged according to the operation state of the target node, the abnormal condition generated in the test is effectively monitored, and the normal realization of the automatic test is ensured.
In an optional mode of the present disclosure, determining a test result by sending a topology query message to a target node includes:
sending a topology query message to a target node;
if receiving topology response information returned by the target node based on the topology query message, determining that the test result is normal;
and if the topology response information returned by the target node based on the topology query message is not received, determining that the test result is abnormal.
In the embodiment of the present disclosure, the operation state of the target node may be normal operation or abnormal. When the target node normally operates, if the topology query message is received, the target node immediately responds and returns topology response information, wherein the topology response information contains the topology information of the target node. When the target node is in an abnormal state and cannot normally operate, if the topology query message is received, the response cannot be performed, and the topology response information cannot be returned.
In the embodiment of the disclosure, the running state of the target node can be judged by whether the topology response information returned by the target node is received or not, when the running state of the target node is abnormal, it can be considered that the variant data packet is processed so that the target node cannot work normally, and at this time, the test result can be determined to be abnormal, so that the effective monitoring of the abnormality generated in the test is realized.
In the embodiment of the present disclosure, after each variant data packet is sent, a topology query message may be sent to the target node to determine a test result for the variant data packet.
As an example, the Topology Query Message may be a "Topology Query Message" in EasyMesh for querying another network node for Topology information. The Topology response Message may be a "Topology response Message" in Easy Mesh, for returning Topology information after receiving the "Topology Query Message". Therefore, the abnormal test monitoring of the automatic fuzzy test in the Easy Mesh network control stage is realized.
In an optional mode of the present disclosure, the method further includes:
and carrying out mutation processing on the pre-acquired original data packet based on a pre-configured mutation strategy to obtain a mutation data packet.
In the embodiment of the present disclosure, the data packet collected under the actual working condition may be used as the original data packet, for example, the data packet may be a data packet of a real Easy Mesh network control stage.
In an optional manner of the present disclosure, the original data packet is a data packet in a Type-Length-Value (Type, Length, Value, TLV) format, and the original data packet acquired in advance is subjected to mutation processing based on a preconfigured mutation policy, where the method includes any one of the following steps:
modifying the value of a Length field in the original data packet;
and modifying a TLV group in the original data packet, wherein the TLV group consists of a Type (Type) field, a Length field and a Value (Value) field.
The data packet in the network control phase of Easy Mesh is based on the Institute of Electrical and Electronics Engineers (IEEE) 1905.1a protocol, in which the data format of the data packet is defined as TLV, wherein the Length field defines the Length of the Value, and the Value field represents the actual Value.
In the embodiment of the present disclosure, the mutation policy may include modifying a Value of a Length field in the original data packet, modifying the Length field to an abnormal Value inconsistent with a Value field, and possibly triggering some memory corruption vulnerabilities in a TLV parsing process.
As an example, modifying the value of the Length field in the original data packet includes:
and modifying the value of the Length field in the original data packet to ensure that the modified value of the Length field is greater than a first preset value or smaller than a second preset value, wherein the first preset value is greater than the second preset value.
The first preset value can be set to be a larger value, the second preset value can be set to be a smaller value, and the value of the Length field is modified, so that the variant value obtained after the variation is too large or too small, the problem of out-of-bounds reading or integer overflow and the like can be caused when the value of the Length field is too small, and the problem of out-of-bounds writing and the like can be caused when the value of the Length field is too large.
In the embodiment of the present disclosure, the mutation policy may also include modifying the TLV group in the original data packet. A triplet of a Type field, a Length field, and a Value field included in one TLV data may be determined as a TLV group. Modification of the TLV set may result in a logical breach related to memory corruption, such as Double-Free (Double-Free), Use-After-release (Use-After-Free), and the like.
As an example, the set of TLVs in the original data packet is modified, including any of:
adding TLV groups in the original data packet;
deleting TLV groups in the original data packet;
the TLV groups in the original data packet are modified.
In the embodiment of the present disclosure, the TLV groups in the original data packet are added, and a mode of copying the original TLV groups in the original data packet may be adopted. And modifying the TLV group in the original data packet, namely correspondingly modifying the Type field, the Length field and the Value field.
In the embodiment of the disclosure, the variant data packet obtained after the variant processing based on the variant strategy is subjected to the fuzzy test, which can cover most problems in TLV analysis.
In an optional manner of the present disclosure, after determining that the test result is abnormal, the method further includes:
and storing the corresponding variant data packet when the test result is abnormal.
In the embodiment of the present disclosure, after it is determined that there is an anomaly in the test, the variant data packet causing the anomaly may be stored, so as to facilitate subsequent analysis to determine a vulnerability.
In the embodiment of the present disclosure, after the test for one variant data packet is completed, if the test result is normal, the test for the next variant data packet may be performed; if the test result is abnormal, the variant data packet causing the abnormality can be stored, and then the target node is restarted.
The scheme provided by the embodiment of the disclosure can be applied to automatic fuzzy test in the control stage of the Easy Mesh network, and vulnerability mining aiming at Easy Mesh is realized. The method does not need manual intervention, can automatically cover all protocol fields of the network control stage of the easy mesh, and cover all memory damage scenes caused by TLV analysis, and has higher test efficiency.
As an example, fig. 2 shows a schematic structural diagram of a test system provided by an embodiment of the present disclosure.

step S330: sending a topology query message to a target node;
step S340: if receiving topology response information returned by the target node based on the topology query message, determining that the test result is normal; and if the topology response information returned by the target node based on the topology query message is not received, determining that the test result is abnormal.
The data packet collected under the actual working condition may be used as an original data packet, for example, the data packet may be a data packet in a control phase of a real Easy Mesh network.
The variant packet is a variant packet used for fuzz testing, and may be, for example, a variant packet in Easy Mesh network control stage.
The target node is configured to process the variant data packet after receiving the variant data packet, and the target node may not be a specific device but be a logical entity, which may be separately deployed in a device or may be deployed in a device together with other target nodes. As an example, the target node may be a network node in a Mesh networking.

In the embodiment of the disclosure, the operation state of the target node can be determined by sending the topology query message to the target node, and the operation state of the target node can reflect the test result.
In the embodiment of the present disclosure, the operation state of the target node may be normal operation or abnormal. When the target node normally operates, if the topology query message is received, the target node immediately responds and returns topology response information, wherein the topology response information contains the topology information of the target node. When the target node is in an abnormal state and cannot normally operate, if the topology query message is received, the response cannot be performed, and the topology response information cannot be returned.
In the embodiment of the disclosure, the running state of the target node can be judged by whether the topology response information returned by the target node is received or not, when the running state of the target node is abnormal, it can be considered that the variant data packet is processed so that the target node cannot work normally, and at this time, the test result can be determined to be abnormal, so that the effective monitoring of the abnormality generated in the test is realized.

As an example, the Topology Query Message may be a "Topology Query Message" in Easy Mesh for querying another network node for Topology information. The Topology response Message may be a "Topology response Message" in Easy Mesh, for returning Topology information after receiving the "Topology Query Message". Therefore, the abnormal test monitoring of the automatic fuzzy test in the Easy Mesh network control stage is realized.
