EUVDB-ID: #VU107322

Risk: Critical

CVSSv4.0: 9.3 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:A/U:Red]

CVE-ID: CVE-2025-30406

CWE-ID: CWE-321 - Use of Hard-coded Cryptographic Key

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to usage of a hard-coded cryptographic key when encrypting ViewState data. A remote non-authenticated attacker can predict the machineKey in use and forge ViewState payloads that pass integrity checks.

Successful exploitation of the vulnerability may allow an attacker to execute arbitrary code on the system with privileges of the Microsoft IIS webserver account. 

Note, the vulnerability is being actively exploited in the wild.

Mitigation

Install updates from vendor's website.
