Overview
CVE-2025-10285 describes a security vulnerability found in the web interface of the Silicon Labs Simplicity Device Manager. This flaw allows an attacker to potentially extract the NTLMv2 hash of a user accessing the exposed web interface. A successful attacker could then attempt to crack this hash offline, potentially gaining unauthorized access to the user’s domain account.
Technical Details
The vulnerability stems from the Simplicity Device Manager’s web interface being accessible without proper authentication or authorization controls. An attacker can potentially trigger a process on the vulnerable interface that forces the user’s browser to attempt authentication using NTLMv2. This authentication attempt transmits the user’s NTLMv2 hash to the attacker-controlled server. The extracted hash can then be subjected to brute-force or dictionary attacks to recover the user’s password.
CVSS Analysis
Currently, a CVSS score has not been assigned to CVE-2025-10285. The severity of the vulnerability is also listed as N/A. However, the potential impact of domain password compromise should be considered significant. A CVSS score will likely be assigned as the vulnerability is analyzed further. Factors influencing the score will include the ease of exploitation, privileges required, and the scope of impact.
Possible Impact
The successful exploitation of CVE-2025-10285 can have severe consequences:
- Domain Account Compromise: An attacker could gain unauthorized access to the user’s domain account, potentially leading to data breaches, system compromise, and further lateral movement within the network.
- Data Exfiltration: A compromised account can be used to steal sensitive data.
- System Disruption: An attacker could disrupt critical business operations.
- Reputational Damage: A security breach can damage the organization’s reputation.
Mitigation or Patch Steps
To mitigate the risks associated with CVE-2025-10285, the following steps are recommended:
- Apply the Security Patch: Silicon Labs will likely release a security patch for the Simplicity Device Manager to address this vulnerability. Apply the patch as soon as it becomes available. Check the Silicon Labs Community for updates.
- Restrict Access: Ensure that the Simplicity Device Manager’s web interface is not publicly accessible. Implement strong network segmentation and access controls to restrict access to authorized users only.
- Implement Strong Authentication: If possible, disable NTLM authentication and enforce the use of stronger authentication mechanisms such as Kerberos. Multi-Factor Authentication (MFA) should also be enabled to add an extra layer of security.
- Monitor Network Traffic: Monitor network traffic for suspicious activity that may indicate an attempted exploitation of this vulnerability.
- Password Complexity: Enforce strong password policies that mandate complex and regularly changed passwords.
