CVE-2024-54015 is a vulnerability in multiple Siemens SIPROTEC 5 protection relays and communication modules, including models such as 6MD84 (CP300 all versions < V9.90), 6MD85/6MD86/6MD89/6MU85 (CP300 versions >= V8.80 < V9.90), 7KE85 (CP300 >= V8.80 < V10.0), 7SA82/7SD82/7SJ81/7SJ82/7SK82/7SL82/7SX82/7SY82/7UT82 (CP150 all < V9.90), various 7SA/7SD/7SJ/7SK/7SL/7SS/7ST/7SX/7SY/7UM/7UT/7VE/7VK/7VU85 (CP300 >= V8.80 < V9.90 or specific subranges), 7ST85/7ST86 (CP300 < V10.0 with subranges), SIPROTEC 5 Compact 7SX800 (CP050 >= V9.50 < V9.90), and communication modules like ETH-BA-2EL/ETH-BB-2FO/ETH-BD-2FO (all versions < V9.90 or subranges). The issue stems from improper validation of SNMP GET requests, enabling disclosure of sensitive information.
An unauthenticated remote attacker can exploit this vulnerability over the network by sending SNMPv2 GET requests using default credentials, achieving high-impact confidentiality loss (CVSS 7.5: AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N) without requiring privileges, user interaction, or scope changes. Successful exploitation allows retrieval of sensitive device information, potentially aiding further attacks on industrial control systems.
Siemens Security Advisory SSA-767615 at https://cert-portal.siemens.com/productcert/html/ssa-767615.html provides details on mitigation, including recommended firmware updates to patched versions such as V9.90 or higher where specified. Security practitioners should review the advisory for affected version mappings and upgrade instructions.

Affected devices do not properly validate SNMP GET requests. This could allow an unauthenticated, remote attacker to retrieve sensitive information of the affected devices with SNMPv2 GET requests using default credentials.

Mitigating Controls (NIST 800-53 r5) AI
Secure configuration settings establish baselines that prohibit default credentials on system components.
Authenticator management requires verification of identity and secure distribution of initial authenticators, directly stopping default credentials from being left in place.
Vulnerability scanning can discover default credentials after deployment but does not stop their introduction.
Account management processes include assignment and control of initial account credentials, reducing the chance defaults remain active.

Hardened baselines and configuration management explicitly prohibit default credentials on deployed systems.
Credential management processes directly require replacing or disabling default passwords and keys.
Authentication policies can enforce non-default credential strength but do not explicitly address initial deployment defaults.

The requirement to replace vendor default authentication information immediately after installation directly counters the use of default credentials that attackers commonly target.
