CVE-2022-36010
No affected components available
This library allows strings to be parsed as functions and stored as a specialized component, JsonFunctionValue. To do this, Javascript's eval function is used to execute strings that begin with "function" as Javascript. This unfortunately could allow arbitrary code to be executed if it exists as a value within the JSON structure being displayed. Given that this component may often be used to display data from arbitrary, untrusted sources, this is extremely dangerous. One important note is that users who have defined a custom onSubmitValueParser callback prop on the JsonTree component should be unaffected. This vulnerability exists in the default onSubmitValueParser prop which calls parse. Prop is added to JsonTree called allowFunctionEvaluation. This prop will be set to true in v2.2.2, which allows upgrade without losing backwards-compatibility. In v2.2.2, we switched from using eval to using Function to construct anonymous functions. This is better than eval for the following reasons: - Arbitrary code should not be able to execute immediately, since the Function constructor explicitly only creates anonymous functions - Functions are created without local closures, so they only have access to the global scope If you use: - Version <2.2.2, you must upgrade as soon as possible. - Version ^2.2.2, you must explicitly set JsonTree's allowFunctionEvaluation prop to false to fully mitigate this vulnerability. - Version >=3.0.0, allowFunctionEvaluation is already set to false by default, so no further steps are necessary.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability. The vulnerability can affect other systems as well, not just the initial system. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
Active exploitation in the wild has been confirmed. Immediate patching or mitigation is required.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
