GHSA-vx2x-9cff-fhjw
DSInternals Credential Roaming Elevation of Privilege Vulnerability
Impact
A vulnerability exists in the DSInternals.Common.Data.RoamedCredential.Save() method, which incorrectly parses the msPKIAccountCredentials LDAP attribute values. As a consequence, a malicious actor would be able to modify the file system of the computer where an application using this function is executed with administrative privileges.
A similar security issue used to be present in the Windows operating system, as DSInternals re-implements the Credential Roaming feature of Windows.
Exploitability
The vulnerability can be exploited under the following circumstances:
- An attacker is able to modify the
msPKIAccountCredentialsattribute of a user account in Active Directory. This attribute is used by the Credential Roaming feature of Windows and each AD user can modify their own roamed credentials. AND - A 3rd party application uses the
DSInternals.Commonlibrary to export roamed credentials from Active Directory to a file system. AND - The application has administrative privileges on the local system.
The probability of any 3rd-party product using the DSInternals.Common library being affected by this vulnerability is extremely low.
Patches
The issue had been fixed in DSInternals 4.8.
