Deserialization of Untrusted Data

CVE-2022-21167

High
9.8/10

Summary

Several Masuit.Tools packages are vulnerable to Arbitrary Code Execution via the "ReceiveVarData<T>" function in the "SocketClient.cs" component. The socket client in the package can pass in the payload via the user-controllable input after it has been established, because this socket client transmission does not have the appropriate restrictions or type bindings for the "BinaryFormatter". This issue affects Masuit.Tools.Abstractions through 2.4.8.2, Masuit.Tools.Core 1.7.7 through 2.2.9.5 and 2.3.1.10 through 2.4.8.2, Masuit.Tools.Net 2.2.8.5 through 2.2.9.5 and 2.3.1.10 through 2.4.9.2, and Masuit.Tools.Net45 2.4.3.3 through 2.4.9.2.

CWE-502 - Deserialization of Untrusted Data

Deserialization of untrusted data vulnerabilities enable an attacker to replace or manipulate a serialized object, replacing it with malicious data. When the object is deserialized at the victim's end the malicious data is able to compromise the victim’s system. The exploit can be devastating, its impact may range from privilege escalation, broken access control, or denial of service attacks to allowing unauthorized access to the application's internal code and logic which can compromise the entire system.
