CVE-2026-7310: CWE-122 Heap-based buffer overflow in Hitachi Energy MACH HiDraw
A heap-based buffer overflow vulnerability exists in XML parser functionality in the HiDraw. An authenticated malicious user with local access can exploit this vulnerability using a specially crafted XML file which may lead to memory corruption and potential arbitrary code execution. Successful exploitation could result in application crashes (denial of service) and compromise the confidentiality and integrity of the affected system.
AI Analysis
Technical Summary
This vulnerability involves a heap-based buffer overflow in the XML parser of MACH HiDraw 9.0. An attacker with local authenticated access can trigger this by submitting a malicious XML file, which may cause memory corruption. The impact includes possible application crashes and potential compromise of system confidentiality and integrity. The CVSS 4.0 vector indicates low attack vector (local), high attack complexity, partial privileges required, and user interaction needed. No patch or official fix has been disclosed by Hitachi Energy as of the publication date.
Potential Impact
Successful exploitation can cause application crashes (denial of service) and may allow compromise of confidentiality and integrity of the affected system. The attacker must have local authenticated access and supply a crafted XML file. There are no known exploits in the wild currently.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict local access to trusted users only and monitor for suspicious activity related to XML file processing in MACH HiDraw.
