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

The cybersecurity world was recently stirred by the discovery of a new Common Vulnerabilities and Exposures (CVE) issue, CVE-2025-47756, a significant vulnerability found in V-SFT v6.2.5.0 and earlier versions. This vulnerability, if exploited, can lead to severe consequences such as system crashes, information disclosure, and even arbitrary code execution. This post aims to provide a detailed analysis of the vulnerability<\/a>, discussing its potential impact, and providing suggestions on how to mitigate the risks associated with it.<\/p>\n

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

CVE ID: CVE-2025-47756
\nSeverity: High (CVSS: 7.8)
\nAttack Vector: Local
\nPrivileges Required: Low
\nUser Interaction: Required
\nImpact: System crash, information disclosure, and arbitrary code<\/a> execution.<\/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 vulnerability stems from an out-of-bounds<\/a> read issue in the VS6EditData!CGamenDataRom::set_mr400_strc function. The flaw is triggered when the software attempts to read data<\/a> that exists outside the intended boundary of a buffer. This occurs when a user opens specially crafted V7 or V8 files, causing the software to read data beyond its allocated memory<\/a>. This can lead to several undesirable outcomes, such as crashing the system, leaking sensitive information, or even allowing an attacker to execute arbitrary code<\/a>.<\/p>\n

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

Here is an example of how this vulnerability might be exploited. This pseudo-code represents a maliciously crafted file that causes an out-of-bounds read<\/a> when opened:<\/p>\n

#include \n#include \nint main() {\nchar buffer[10];\nFILE *file = fopen(\"malicious.v7\", \"rb\");\nif (file == NULL) {\nprintf(\"Cannot open file \\n\");\nreturn 1;\n}\nfread(buffer, sizeof(char), 15, file);\nfclose(file);\nprintf(\"Buffer contains: %s\\n\", buffer);\nreturn 0;\n}<\/code><\/pre>\n
In this example, the program attempts to read 15 characters into a buffer that only has space for 10. This will result in an out-of-bounds read<\/a>.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
To mitigate the risks associated with this vulnerability<\/a>, users of V-SFT v6.2.5.0 and earlier should apply the vendor’s patch as soon as it becomes available. This patch will correct the out-of-bounds read issue, thereby preventing potential exploits<\/a>. In the meantime, users can use Web Application<\/a> Firewalls (WAF) or Intrusion Detection Systems (IDS) as temporary mitigation measures. These systems can help detect and block attempts to exploit the vulnerability<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
