CVE-2025-3426 | Use of default hardcoded credentials

We observed that Intellispace Portal binaries doesn’t have any protection mechanisms to prevent reverse engineering. Specifically, the app’s code is not obfuscated, and no measures are in place to protect against decompilation, disassembly, or debugging. As a result, attackers can reverse-engineer the application to gain insights into its internal workings, which can potentially lead to the discovery of sensitive information, business logic flaws, and other vulnerabilities. Utilizing this flaw, the attacker was able to identify the Hardcoded credentials from PortalUsersDatabase.dll, which contains .NET remoting definition. Inside the namespace PortalUsersDatabase, the class Users contains the functions CreateAdmin and CreateService that are used to initialize accounts in the Portal service. Both CreateAdmin and CreateService functions contain a hardcoded encrypted password along with its respective salt that are set with the function SetInitialPasswordAndSalt. This issue affects IntelliSpace Portal: 12 and prior; Advanced Visualization Workspace: 15.

Attack vector (AV:L)
Attacker needs local access on the target system.
Attack complexity (AC:H)
Exploitation depends on constrained or hard-to-reproduce conditions.
Attack requirements (AT:N)
No additional preconditions are required beyond normal reachability.
Privileges required (PR:N)
No privileges are required.
User interaction (UI:N)
No user interaction is required.
Vulnerable system confidentiality impact (VC:H)
High confidentiality impact on the vulnerable system.
Vulnerable system integrity impact (VI:N)
No integrity impact on the vulnerable system.

Not defined: insufficient information; scoring treats this like High (worst case).
Integrity requirement (IR:X)
Not defined: insufficient information; scoring treats this like High (worst case).
Availability requirement (AR:X)
Not defined: insufficient information; scoring treats this like High (worst case).
Modified attack vector (MAV:X)
Not defined: scoring uses the Base Attack Vector (AV).
Modified attack complexity (MAC:X)
Not defined: scoring uses the Base Attack Complexity (AC).
Modified attack requirements (MAT:X)
Not defined: scoring uses the Base Attack Requirements (AT).
Modified privileges required (MPR:X)
Not defined: scoring uses the Base Privileges Required (PR).
Modified user interaction (MUI:X)
