Overview

Multiple vulnerabilities have been reported in Siemens Products, which could be exploited by a remote attacker to trigger information disclosure, denial of service and remote code execution on the targeted system.

Description

1. Remote Code Execution Vulnerability in Siemens Simcenter Amesim ( CVE-2023-43625   )

This vulnerability exists in Siemens Simcenter Amesim due to a flaw in the SOAP endpoint. A remote attacker could exploit this vulnerability by sending a specially crafted request to perform a DLL injection.
Successful exploitation of this vulnerability could allow a remote attacker to execute arbitrary code in the context of the application process.

2. Buffer Overflow Vulnerability in Siemens SCALANCE ( CVE-2023-22779   CVE-2023-22780   CVE-2023-22781   CVE-2023-22782   CVE-2023-22783   CVE-2023-22784   CVE-2023-22785   CVE-2023-22786   )


These vulnerabilities exist in Siemens SCALANCE due to improper bounds checking by the PAPI protocol. A remote attacker could exploit these vulnerabilities by sending specially crafted packets destined to the PAPI (Arubas access point management protocol) UDP port (8211).
Successful exploitation of these vulnerabilities could allow a privileged remote attacker to execute arbitrary code to cause buffer overflow on the underlying operating system.

3. Denial of Service (DoS) Vulnerability in Siemens SCALANCE ( CVE-2023-22787   )

This vulnerability exists in Siemens SCALANCE due to a flaw in the PAPI protocol. A remote attacker could exploit this vulnerability by sending a specially crafted request.
Successful exploitation of this vulnerability could allow a remote attacker to cause a Denial of Service (DoS) condition on the underlying operating system.

4. Command Injection Vulnerability in Siemens SCALANCE ( CVE-2023-22788   CVE-2023-22789   CVE-2023-22790   )

These vulnerabilities exist in Siemens SCALANCE due to a command injection flaw in the command line interface. A remote attacker could exploit these vulnerabilities by sending a specially crafted request.
Successful exploitation of these vulnerabilities could allow a remote attacker to execute arbitrary commands as a privileged user on the underlying operating system.

5. Information Disclosure Vulnerability in Siemens SCALANCE ( CVE-2023-22791   )

This vulnerability exists in Siemens SCALANCE when possessing valid user credentials via WLAN. A remote attacker could exploit this vulnerability to obtain sensitive information and use this information to launch further attacks against the affected system.
Successful exploitation of this vulnerability could allow a remote attacker to disclose sensitive information.

6. Vulnerability in Siemens CPCI85 firmware ( CVE-2023-36380   )

This vulnerability exists in Siemens CPCI85 Firmware of SICAM A8000 Devices due to the presence of a hard-coded ID in the SSH authorized_keys configuration file. A remote attacker could exploit this vulnerability by using the hard-coded credentials.
Successful exploitation of this vulnerability could allow a remote attacker to completely compromise the target system.

7. Information Disclosure Vulnerability in Siemens Mendix Forgot Password ( CVE-2023-43623   )

This vulnerability exists in Siemens Mendix Forgot Password due to distinguishable responses. A remote attacker could exploit this vulnerability by utilizing brute force attack techniques to enumerate user information.
Successful exploitation of this vulnerability could allow a remote attacker to gain unauthorized access to sensitive information on the target system.

Workaround

  • CVE-2023-43625: Limit ports 40002 to 41000 to be accessible only from localhost.
  • CVE-2023-22779, CVE-2023-22780, CVE-2023-22781, CVE-2023-22782, CVE-2023-22783, CVE-2023-22784, CVE-2023-22785, CVE-2023-22786: Enable cluster-security via the cluster-security command.
  • Restrict the command line interface and web-based management interfaces to a dedicated layer 2 segment/VLAN and/or control them by firewall policies at layer 3 and above.
  • CVE-2023-22787: Block access to port UDP/8211 from untrusted networks
