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

The recently discovered vulnerability, CVE-2025-54245, affecting Substance3D – Viewer versions 0.25.1 and earlier, poses a serious threat to users due to its potential for arbitrary code execution in the context of the current user. The vulnerability, which requires user interaction for exploitation, could lead to severe system compromise or data leakage, highlighting the need for immediate attention and mitigation.<\/p>\n

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

CVE ID: CVE-2025-54245
\nSeverity: High – CVSS 7.8
\nAttack Vector: File-based
\nPrivileges Required: User
\nUser Interaction: Required
\nImpact: Potential system<\/a> compromise or data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

Substance3D – Viewer | 0.25.1 and earlier<\/p>\n

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

The out-of-bounds write vulnerability<\/a> in Substance3D – Viewer allows an attacker to execute arbitrary code in the context of the current user. This is achieved by tricking the user into opening a malicious file, which triggers the vulnerability and results in unauthorized write<\/a> access beyond the allocated memory bounds. The attacker can leverage this to inject and execute malicious code<\/a>, potentially leading to system compromise or data leakage.<\/p>\n

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

Here’s a conceptual example of how the exploit might occur. Assume that an attacker sends a malicious file to the victim, who opens the file using Substance3D – Viewer, triggering the vulnerability:<\/p>\n

\/\/ Malicious payload\nchar buffer[500];\nFILE *fp;\nfp = fopen(\"malicious_file.s3d\", \"r\");\nfread(buffer, 1, 1000, fp);  \/\/ Out-of-bounds write vulnerability triggered here<\/code><\/pre>\n
The `fread` function attempts to read more data into the buffer than what it can hold, resulting in an out-of-bounds write vulnerability<\/a>. This can be exploited to execute arbitrary code in the context of the current user.<\/p>\n","protected":false},"excerpt":{"rendered":"
