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

The CVE-2025-57637 vulnerability was identified in the D-Link DI-7100G’s jhttpd service, specifically in the sub_451754 function of the viav4 parameter. This buffer overflow vulnerability can be exploited by attackers to cause a denial of service or execute arbitrary code, potentially leading to system compromise or data leakage. It is, therefore, critical for users of this product to understand the implications of this vulnerability and take the necessary mitigation steps.<\/p>\n

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

CVE ID: CVE-2025-57637
\nSeverity: High (7.5 CVSS Score)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Denial of Service, Execution of Arbitrary Code, Potential System Compromise, Data Leakage<\/p>\n

Product | Affected Versions<\/p>\n

D-Link DI-7100G | 2020-02-21<\/p>\n

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

The exploit takes advantage of a buffer overflow vulnerability in the sub_451754 function of the jhttpd service’s viav4 parameter. By sending crafted network packets that exceed the buffer’s memory allocation, an attacker can cause the system to overflow. This overflow can lead to a denial of service, or worse, provide the attacker with the ability to execute arbitrary code on the system.<\/p>\n

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

The following is a simplified, conceptual example of how the vulnerability might be exploited.<\/p>\n
