Summary
CVE-2026-24497 is a high-severity Stack-based Buffer Overflow (CWE-121) vulnerability in Thinkwise Thinkwise. Its CVSS base score is 8.4 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 25.3th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and SI-16 (Memory Protection).
Deeper analysis
CVE-2026-24497 is a stack-based buffer overflow vulnerability in ThinkWise software from SimTech Systems, Inc., which enables remote code inclusion. The issue affects ThinkWise versions from 7 through 23 and is associated with CWE-121 (stack-based buffer overflow) and CWE-787 (out-of-bounds write). It received a CVSS v3.1 base score of 9.8, reflecting its critical severity due to network accessibility, low attack complexity, and lack of prerequisites.
Remote, unauthenticated attackers can exploit this vulnerability over the network without user interaction. Successful exploitation allows attackers to achieve high-impact confidentiality, integrity, and availability effects, including remote code execution on the affected system.
Mitigation details are outlined in vendor and advisory publications, including a patch notice from ThinkWise at https://www.thinkwise.co.kr/bbs/board.php?bo_table=patch&wr_id=19352 and a Korean advisory at https://www.boho.or.kr/kr/bbs/view.do?searchCnd=&bbsId=B0000302&searchWrd=&menuNo=205023&pageIndex=1&categoryCode=&nttId=71985. Security practitioners should consult these references for patching instructions and apply updates to vulnerable versions promptly.
