ICSA-24-046-10: Siemens Simcenter Femap

CISA's summary

Summary: Simcenter Femap contains multiple file parsing vulnerabilities that could be triggered when the application reads files in Catia MODEL file formats. If a user is tricked to open a malicious file with any of the affected products, this could lead the application to crash or potentially lead to arbitrary code execution. Siemens has released a new version for Simcenter Femap and recommends to update to the latest version.

Vulnerabilities in this advisory

• CVE-2024-24920 — CVE-2024-24920 · CWE-787

  The affected application contains an out of bounds write past the end of an allocated buffer while parsing a specially crafted Catia MODEL file. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-21710)

• CVE-2024-24921 — CVE-2024-24921 · CWE-119

  The affected application is vulnerable to memory corruption while parsing specially crafted Catia MODEL files. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-21712)

• CVE-2024-24922 — CVE-2024-24922 · CWE-787

  The affected application contains an out of bounds write past the end of an allocated buffer while parsing a specially crafted Catia MODEL file. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-21715)

• CVE-2024-24923 — CVE-2024-24923 · CWE-125

  The affected applications contain an out of bounds read past the end of an allocated structure while parsing specially crafted Catia MODEL files. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-22055)

• CVE-2024-24924 — CVE-2024-24924 · CWE-787

  The affected application contains an out of bounds write past the end of an allocated buffer while parsing a specially crafted Catia MODEL file. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-22059)

• CVE-2024-24925 — CVE-2024-24925 · CWE-824

  The affected application is vulnerable to uninitialized pointer access while parsing specially crafted Catia MODEL files. An attacker could leverage this vulnerability to execute code in the context of the current process. (ZDI-CAN-22060)

• CVE-2024-27907 — CVE-2024-27907 · CWE-787

  The affected application contains an out of bounds write past the end of an allocated buffer while parsing a specially crafted Catia MODEL file. This could allow an attacker to execute code in the context of the current process. (ZDI-CAN-22051)
