Successful exploitation of these vulnerabilities could allow an attacker to disclose information and to execute arbitrary code.
The following versions of Horner Automationβs Cscape are affected:
3.2.1 STACK-BASED BUFFER OVERFLOW CWE-121
The affected application lacks proper validation of user-supplied data when parsing project files (e.g., CSP). This could lead to a stack-based buffer overflow. An attacker could leverage this vulnerability to execute arbitrary code in the context of the current process.
CVE-2023-29503 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 OUT-OF-BOUNDS READ CWE-125
The affected application lacks proper validation of user-supplied data when parsing project files (e.g., CSP). This could lead to an out-of-bounds read in the FontManager. An attacker could leverage this vulnerability to execute arbitrary code in the context of the current process.
CVE-2023-32281 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 OUT-OF-BOUNDS READ CWE-125
The affected application lacks proper validation of user-supplied data when parsing project files (e.gβ¦, CSP). This could lead to an out-of-bounds read in IO_CFG. An attacker could leverage this vulnerability to execute arbitrary code in the context of the current process.
CVE-2023-32289 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 OUT-OF-BOUNDS READ CWE-125
The affected application lacks proper validation of user-supplied data when parsing project files (e.g., CSP). This could lead to an out-of-bounds read in Cscape!CANPortMigration. An attacker could leverage this vulnerability to execute arbitrary code in the context of the current process.
CVE-2023-32545 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 READ CWE-125
The affected application lacks proper validation of user-supplied data when parsing font files (e.g., FNT). This could lead to an out-of-bounds read. An attacker could leverage this vulnerability to potentially execute arbitrary code in the context of the current process.
CVE-2023-27916 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).
3.2.6 USE AFTER FREE CWE-416
The affected application lacks proper validation of user-supplied data when parsing project files (e.g., CSP). This could lead to a use-after-free vulnerability. An attacker could leverage this vulnerability to execute arbitrary code in the context of the current process.
CVE-2023-28653 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).
3.2.7 ACCESS OF UNINITIALIZED POINTER CWE-824
The affected product does not properly validate user-supplied data. If a user opens a maliciously formed CSP file, then an attacker could execute arbitrary code within the current process by accessing an uninitialized pointer.
CVE-2023-31244 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).
3.2.8 IMPROPER RESTRICTION OF OPERATIONS WITHIN THE BOUNDS OF A MEMORY BUFFER CWE-119
The affected application lacks proper validation of user-supplied data when parsing project files (e.g., HMI). This could lead to an out-of-bounds write at CScape_EnvisionRV+0x2e374b. An attacker could leverage this vulnerability to execute arbitrary code in the context of the current process.
CVE-2023-32203 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).
3.2.9 IMPROPER RESTRICTION OF OPERATIONS WITHIN THE BOUNDS OF A MEMORY BUFFER CWE-119
The affected application lacks proper validation of user-supplied data when parsing project files (e.g., HMI). This could lead to an out-of-bounds write at CScape_EnvisionRV+0x2e3c04. An attacker could leverage this vulnerability to potentially execute arbitrary code in the context of the current process.
CVE-2023-32539 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).
3.2.10 IMPROPER RESTRICTION OF OPERATIONS WITHIN THE BOUNDS OF A MEMORY BUFFER CWE-119
The affected application lacks proper validation of user-supplied data when parsing project files (e.g., HMI). This could lead to an out-of-bounds read. An attacker could leverage this vulnerability to potentially execute arbitrary code in the context of the current process.
CVE-2023-31278 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).
Michael Heinzl reported these vulnerabilities to CISA.
Horner Automation recommends upgrading the following software:
CISA reminds organizations to perform proper impact analysis and risk assessment prior to deploying defensive measures.
CISA also provides a section for control systems security recommended practices on the ICS webpage at cisa.gov/ics. Several CISA products detailing cyber defense best practices are available for reading and download, including Improving Industrial Control Systems Cybersecurity with Defense-in-Depth Strategies.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01BβTargeted Cyber Intrusion Detection and Mitigation Strategies.
Organizations observing suspected malicious activity should follow established internal procedures and report findings to CISA for tracking and correlation against other incidents.
CISA also recommends users take the following measures to protect themselves from social engineering attacks:
No known public exploits specifically target these vulnerabilities. These vulnerabilities are not exploitable remotely.
