Overview<\/strong><\/p>\n

CVE-2025-47754 is a critical security vulnerability affecting V-SFT v6.2.5.0 and earlier versions. The vulnerability resides in the VS6EditData!Conv_Macro_Data function. It is a severe out-of-bounds read vulnerability that can be exploited if a user opens<\/a> specially crafted V7 or V8 files. The exploit may lead to system crashes, unauthorized information disclosure, and arbitrary code<\/a> execution. In the worst-case scenario, this could potentially compromise an entire system or lead<\/a> to significant data leakage.
\nThis vulnerability is particularly alarming due<\/a> to its potential impact on users and systems utilizing V-SFT. As a widely used software in industrial automation, any compromise or data leakage could lead<\/a> to significant operational disruptions and financial losses. The vulnerability\u2019s severity<\/a> is underlined by its CVSS Severity Score of 7.8, indicating its high-risk nature.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-47754
\nSeverity: High (CVSS: 7.8)
\nAttack Vector: Local
\nPrivileges Required: Low
\nUser Interaction: Required
\nImpact: System crash, information disclosure, and arbitrary code execution<\/a><\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

V-SFT | v6.2.5.0<\/a> and earlier<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploit takes advantage of an out-of-bounds read vulnerability<\/a> in the VS6EditData!Conv_Macro_Data function of V-SFT. This vulnerability is triggered when a user<\/a> opens a maliciously crafted V7 or V8 file. The file contains specially crafted data that, when parsed by the vulnerable function, causes the software to read beyond the allocated memory<\/a>. This can lead to a system crash, information disclosure, and potentially arbitrary code execution if the attacker has carefully controlled the data in the file to manipulate memory in a way that allows<\/a> them to execute code.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

This is a conceptual example of how the vulnerability might be exploited. An attacker could craft a V7 or V8 file with malicious data embedded within. When this file is opened in V-SFT, it would trigger the vulnerability<\/a>:<\/p>\n

$ echo \"malicious_data\" > crafted.v7<\/code><\/pre>\n
In this example, the “malicious_data” would be specifically designed to exploit the out-of-bounds read vulnerability<\/a> in the VS6EditData!Conv_Macro_Data function. When the user opens this file in the vulnerable<\/a> V-SFT software, it would lead to a system crash, information disclosure, or arbitrary code execution.
\nWhile this is a simplified example, an actual exploit would likely involve more complex data manipulation and careful crafting of the malicious file<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
