Teamcenter V2312: Use of Hard-coded Credentials
CVE-2026-33893 is a high-severity use of hard-coded credentials vulnerability in Teamcenter V2312 from Siemens, with a CVSS 3.1 base score of 7.5 out of 10. It can be exploited remotely over the network by an unauthenticated attacker, without any action from a user. The record lists version V2312.0014 as the first without the flaw, so updating Teamcenter V2312 to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.29% chance of exploitation within 30 days, which is low compared with other CVEs.
High severity with no evidence of exploitation so far.
What to do
- Update Teamcenter V2312 to V2312.0014 or a later version.
- Update Teamcenter V2406 to V2406.0012 or a later version.
- Update Teamcenter V2412 to V2412.0009 or a later version.
- Read the advisory on cert-portal.siemens.com for workarounds and exact fixed builds.
- Until you can update, restrict network access to the affected service so it is not reachable from untrusted networks.

Official description
A vulnerability has been identified in Teamcenter V2312 (All versions < V2312.0014), Teamcenter V2406 (All versions < V2406.0012), Teamcenter V2412 (All versions < V2412.0009), Teamcenter V2506 (All versions < V2506.0005), Teamcenter V2512 (All versions). The affected application contains hardcoded key which is used for obfuscation stored directly into the application. This could allow an attacker to obtain these keys and misuse them to gain unauthorized access.

The underlying weakness: Use of Hard-coded Credentials
The product contains hard-coded credentials, such as a password or cryptographic key.
How developers prevent this class of flaw
- For outbound authentication: store passwords, keys, and other credentials outside of the code in a strongly-protected, encrypted configuration file or database that is protected from access by all outsiders, including other local users on the same system. Properly protect the key (CWE-320). If you cannot use encryption to protect the file, then make sure that the permissions are as restrictive as possible. In Windows environments, the Encrypted File System (EFS) may provide some protection.
- For inbound authentication: Rather than hard-code a default username and password, key, or other authentication credentials for first time logins, utilize a first login mode that requires the user to enter a unique strong password or key.
- If the product must contain hard-coded credentials or they cannot be removed, perform access control checks and limit which entities can access the feature that requires the hard-coded credentials. For example, a feature might only be enabled through the system console instead of through a network connection.
