Successful exploitation of these vulnerabilities could allow an attacker to disclose information and execute arbitrary code.
The following Santesoft products are affected:
3.2.1 OUT-OF-BOUNDS-WRITE CWE-787
Sante DICOM Viewer Pro lacks proper validation of user-supplied data when parsing DICOM files. This could lead to an out-of-bounds write. An attacker could leverage this vulnerability to execute arbitrary code in the context of the current process.
CVE-2023-39431 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 STACK-BASED BUFFER OVERFLOW CWE-121
Sante DICOM Viewer Pro lacks proper validation of user-supplied data when parsing DICOM files. 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-2023-35986 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.
Santesoft released an updated version of their product and recommends updating Sante DICOM Viewer Pro to v12.2.6.
CISA also recommends users take the following measures to protect themselves from social engineering attacks:
CISA recommends users take defensive measures to minimize the risk of exploitation of these vulnerabilities. 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 on 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.
CISA encourages organizations to implement recommended cybersecurity strategies for proactive defense of ICS assets.
Additional mitigation guidance and recommended practices are publicly available on the ICS webpage at cisa.gov/ics in the technical information paper, ICS-TIP-12-146-01B–Targeted 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.
No known public exploitation specifically targeting these vulnerabilities has been reported to CISA at this time. These vulnerabilities are not exploitable remotely.
