ICSA-23-285-10: Siemens Tecnomatix Plant Simulation

CISA's summary

Summary: Siemens Tecnomatix Plant Simulation contains multiple vulnerabilities that could be triggered when the application reads SPP and IGS files. If a user is tricked to open a malicious file using the affected application, this could lead to a crash, and potentially also to arbitrary code execution on the target host system. Siemens has released updates for the affected products and recommends to update to the latest versions.

Vulnerabilities in this advisory

• CVE-2023-44081 — CVE-2023-44081 · CWE-787

  The affected application contains an out of bounds write past the end of an allocated buffer while parsing a specially crafted SPP file. This could allow an attacker to execute code in the context of the current process.

• CVE-2023-44082 — CVE-2023-44082 · CWE-787

  The affected application contains an out of bounds write past the end of an allocated buffer while parsing a specially crafted SPP file. This could allow an attacker to execute code in the context of the current process.

• CVE-2023-44083 — CVE-2023-44083 · CWE-787

  The affected application contains an out of bounds write past the end of an allocated buffer while parsing a specially crafted SPP file. This could allow an attacker to execute code in the context of the current process.
