Successful exploitation of these vulnerabilities could crash the device being accessed or allow arbitrary code execution.
The following versions of CIMPLICITY, an HMI/SCADA software, are affected:
3.2.1 ACCESS OF UNINITIALIZED POINTER CWE-824
The affected product is vulnerable when data from a faulting address controls code flow starting at gmmiObj!CGmmiRootOptionTable, which could allow an attacker to execute arbitrary code.
CVE-2022-3084 has been assigned to this vulnerability. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
3.2.2 ACCESS OF UNINITIALIZED POINTER CWE-824
The affected product is vulnerable when data from a faulting address controls code flow starting at gmmiObj!CGmmiOptionContainer, which could allow an attacker to execute arbitrary code.
CVE-2022-2952 has been assigned to this vulnerability. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
3.2.3 HEAP-BASED BUFFER OVERFLOW CWE-122
The affected product is vulnerable to a heap-based buffer overflow, which could allow an attacker to execute arbitrary code.
CVE-2022-2948 has been assigned to this vulnerability. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
3.2.4 UNTRUSTED POINTER DEREFERENCE CWE-822
The affected product is vulnerable when data from faulting address controls code flow starting at gmmiObj!CGmmiOptionContainer, which could allow an attacker to execute arbitrary code.
CVE-2022-2002 has been assigned to this vulnerability. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
3.2.5 OUT-OF-BOUNDS WRITE CWE-787
The affected product is vulnerable to an out-of-bounds write, which could allow an attacker to execute arbitrary code.
CVE-2022-3092 has been assigned to this vulnerability. A CVSS v3 base score of 7.8 has been calculated; the CVSS vector string is (AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H).
