Successful exploitation of these vulnerabilities could result in a variety of issues, including disclosure of data and loss of control of the SCADA system with IGSS running in production mode.
Schneider Electric reports these vulnerabilities affect the following IGSS Data Server module:
A vulnerability exists that could cause heap-based buffer overflow, leading to denial of service and potentially remote code execution when an attacker sends multiple specially crafted messages.
CVE-2022-24310 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
A vulnerability exists that could cause modification of an existing file by inserting data at the beginning of the file or creating a new file in the context of the data server. This could potentially lead to remote code execution when an attacker sends a specially crafted message.
CVE-2022-24311 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
A vulnerability exists that could cause modification of an existing file by adding data at the end of the file or creating a new file in the context of the data server. This could potentially lead to remote code execution when an attacker sends a specially crafted message.
CVE-2022-24312 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
A vulnerability exists that could cause a stack-based buffer overflow potentially leading to remote code execution when an attacker sends a specially crafted message.
CVE-2022-24313 has been assigned to this vulnerability. A CVSS v3 base score of 9.8 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H).
A vulnerability exists that could cause memory leaks potentially resulting in denial of service when an attacker repeatedly sends a specially crafted message.
CVE-2022-24314 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).
A vulnerability exists that could cause denial of service when an attacker repeatedly sends a specially crafted message.
CVE-2022-24315 has been assigned to this vulnerability. A CVSS v3 base score of 7.5 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H).
A vulnerability exists that could cause information exposure when an attacker sends a specially crafted message.
CVE-2022-24316 has been assigned to this vulnerability. A CVSS v3 base score of 5.3 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).
A vulnerability exists that could cause information exposure when an attacker sends a specific message.
CVE-2022-24317 has been assigned to this vulnerability. A CVSS v3 base score of 5.3 has been calculated; the CVSS vector string is (AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N).
These vulnerabilities were reported to Schneider Electric and CISA separately by Tenable, and by Vyacheslav Moskvin working with Trend Micro’s Zero Day Initiative.
Version 15.0.0.22021 of IGSS Data Server includes corrections for these vulnerabilities and is available for download through IGSS Master > Update IGSS Software.
Schneider Electric recommends users use appropriate patching methodologies when applying these patches to their systems. They strongly recommend the use of back-ups and evaluating the impact of these patches in a test and development environment or on an offline infrastructure. Contact Schneider Electric’s Customer Care Center for assistance removing a patch.
If users choose not to apply the remediation provided above, they should immediately apply the following mitigations to reduce the risk of exploit:
Schneider Electric strongly recommends the following industry cybersecurity best practices.
