CVE-2025-47753 is a high-severity vulnerability affecting FUJI ELECTRIC CO., LTD.'s V-SFT software, specifically versions 6.2.5.0 and earlier. The flaw exists in the function VS6EditData!CDrawSLine::GetRectArea, which handles the parsing of V7 or V8 file formats. The vulnerability is an out-of-bounds read, meaning the software reads memory outside the intended buffer boundaries when processing specially crafted files. This can lead to multiple adverse effects including application crashes (denial of service), information disclosure by leaking memory contents, and potentially arbitrary code execution if exploited correctly. The CVSS 3.1 base score is 7.8, indicating a high impact, with an attack vector of local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), but requiring user interaction (UI:R). The scope is unchanged (S:U), and the impact on confidentiality, integrity, and availability is high (C:H/I:H/A:H). Since exploitation requires opening a malicious file locally, the attack surface is limited to users who interact with untrusted V7 or V8 files. No known exploits are currently reported in the wild, but the vulnerability poses a significant risk due to the possibility of arbitrary code execution. The lack of available patches at the time of publication increases the urgency for mitigation. This vulnerability is particularly critical for environments where V-SFT is used to process or exchange V7/V8 files, especially in industrial or critical infrastructure contexts where FUJI ELECTRIC products are deployed.

For European organizations, the impact of CVE-2025-47753 can be substantial, especially those in industrial automation, manufacturing, and critical infrastructure sectors where FUJI ELECTRIC's V-SFT software is utilized. Successful exploitation could lead to unauthorized disclosure of sensitive operational data, disruption of industrial control processes due to crashes, or full system compromise through arbitrary code execution. This could result in operational downtime, safety risks, and potential regulatory non-compliance under GDPR if personal or sensitive data is exposed. The requirement for local access and user interaction somewhat limits remote exploitation, but insider threats or phishing campaigns delivering malicious files could still trigger attacks. The high integrity and availability impact means that critical production systems could be manipulated or halted, affecting supply chains and service delivery. Given the strategic importance of industrial control systems in Europe, this vulnerability could have cascading effects on national infrastructure and economic activities.

European organizations should implement the following specific mitigations: 1) Immediately restrict the handling of V7 and V8 files to trusted sources only and educate users about the risks of opening files from unverified origins. 2) Employ application whitelisting and sandboxing techniques for V-SFT to contain potential exploitation and prevent arbitrary code execution from escalating privileges. 3) Monitor and audit file access and application crashes related to V-SFT to detect anomalous behavior indicative of exploitation attempts. 4) Coordinate with FUJI ELECTRIC for timely patch releases and apply updates as soon as they become available. 5) Implement endpoint detection and response (EDR) solutions with signatures or heuristics tuned to detect exploitation patterns of out-of-bounds reads and memory corruption in V-SFT. 6) Limit local user privileges on systems running V-SFT to reduce the impact scope if exploitation occurs. 7) Consider network segmentation to isolate systems running V-SFT from broader enterprise networks to contain potential breaches.
