1. EXECUTIVE SUMMARY

• CVSS v3 10.0
• ATTENTION: Exploitable remotely/low attack complexity
• Vendor: Siemens
• Equipment: Cerberus PRO UL and Desigo Fire Safety UL
• Vulnerabilities: Classic Buffer Overflow, Out-of-bounds Read, Improper Restriction of Operations within the Bounds of a Memory Buffer

2. RISK EVALUATION

Successful exploitation of the vulnerabilities could allow an unauthenticated attacker, who gained access to the fire protection system network, to execute arbitrary code on the affected products (CVE-2024-22039) or create a denial-of-service condition (CVE-2024-22040, CVE-2024-22041).

3. TECHNICAL DETAILS 3.1 AFFECTED PRODUCTS

The following products of Siemens, are affected:

• Siemens Cerberus PRO UL Compact Panel FC922/924: All versions prior to MP4
• Siemens Cerberus PRO UL Engineering Tool: All versions prior to MP4
• Siemens Cerberus PRO UL X300 Cloud Distribution: All versions prior to V4.3.0001

• Siemens Desigo Fire Safety UL Engineering Tool: All versions prior to MP4
• Siemens Desigo Fire Safety UL X300 Cloud Distribution: All versions prior to V4.3.0001

3.2 Vulnerability Overview 3.2.1 BUFFER COPY WITHOUT CHECKING SIZE OF INPUT ('CLASSIC BUFFER OVERFLOW') CWE-120

The network communication library in affected systems does not validate the length of certain X.509 certificate attributes which might result in a stack-based buffer overflow. This could allow an unauthenticated remote attacker to execute code on the underlying operating system with root privileges. For Cerberus PRO UL Engineering Tool and Desigo Fire Safety UL Engineering Tool, successful exploitation requires an on-path attacker that intercepts the communication of the engineering tool in the fire system network; code execution might be possible on the underlying operating system with the privileges of the engineering tool user account.

CVE-2024-22039 has been assigned to this vulnerability. A CVSS v3 base score of 10.0 has been assigned; the CVSS vector string is (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H).

A CVSS v4 score has been calculated for CVE-2024-22039. A base score of 10.0 has been calculated; the CVSS vector string is (CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H).

3.2.2 OUT-OF-BOUNDS READ CWE-125

The network communication library in affected systems insufficiently validates HMAC values which might result in a buffer overread. This could allow an unauthenticated remote attacker to crash the network service. For Cerberus PRO UL Engineering Tool and Desigo Fire Safety UL Engineering Tool, successful exploitation requires an on-path attacker that intercepts the communication of the engineering tool in the fire system network; possible impact is limited to the tool, not the underlying operating system.

CVE-2024-22040 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been assigned; the CVSS vector string is (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).

A CVSS v4 score has been calculated for CVE-2024-22040. A base score of 8.7 has been calculated; the CVSS vector string is (CVSS:4.0/V:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:H/SI:H/SA:H).

3.2.3 IMPROPER RESTRICTION OF OPERATIONS WITHIN THE BOUNDS OF A MEMORY BUFFER CWE-119

The network communication library in affected systems improperly handles memory buffers when parsing X.509 certificates. This could allow an unauthenticated remote attacker to crash the network service. For Cerberus PRO UL Engineering Tool and Desigo Fire Safety UL Engineering Tool, successful exploitation requires an on-path attacker that intercepts the communication of the engineering tool in the fire system network; possible impact is limited to the tool, not the underlying operating system.

CVE-2024-22041 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been assigned; the CVSS vector string is (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).

A CVSS v4 score has been calculated for CVE-2024-22041. A base score of 8.7 has been calculated; the CVSS vector string is (CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N).

3.4 RESEARCHER

Hanno Böck reported these vulnerabilities to CISA.

4. MITIGATIONS

alpitronic recommends users change the default credentials for all charging devices.

alpitronic advises that the interface should be connected only to internal segregated and access-controlled networks and not exposed to the public internet/web.

When informed of these vulnerabilities, alpitronic, in conjunction with and/or on behalf of affected clients, disabled the interface on any exposed devices and all clients were contacted directly and reminded that the interface is not intended to be visible on the public Internet and that default passwords should be changed.

alpitronic are also applying mitigations to all devices in the field and to new devices in production. New devices will come with unique passwords. Devices using the default password will be automatically assigned new unique passwords, or at first access if the device has not yet been installed. Devices with the default passwords already changed will not be affected. New passwords can be obtained by scanning the QR-Code inside the charger or in DMS portal hyperdoc. Contact Hypercharger support with any questions about newly assigned passwords.

CISA recommends users take defensive measures to minimize the risk of exploitation of this vulnerability, such as:
