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

A critical vulnerability, tagged as CVE-2025-7910, has been identified in D-Link DIR-513 routers version 1.10. This vulnerability is of significant concern as it affects the function sprintf of the file \/goform\/formSetWanNonLogin of the Boa Webserver component. The vulnerability could be exploited remotely<\/a>, and the exploit has been publicly disclosed, making the affected systems a potential target for cybercriminals. Given the criticality of this vulnerability<\/a>, it is crucial for users and administrators to understand the risks involved and take necessary precautions.<\/p>\n

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

CVE ID: CVE-2025-7910
\nSeverity: Critical (8.8 CVSS Score)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Potential system<\/a> compromise and data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

D-Link DIR-513<\/a> | 1.10<\/p>\n

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

The vulnerability emanates from an incorrect use of the sprintf function in the file \/goform\/formSetWanNonLogin of the Boa Webserver component, leading to a stack-based buffer overflow<\/a>. This vulnerability is triggered when an excessively long ‘curTime’ argument is passed, causing the stack buffer to overflow<\/a>. This overflow can be exploited by an attacker to execute arbitrary<\/a> code or potentially compromise the system’s integrity and confidentiality.<\/p>\n

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

Here is a
\nconceptual<\/strong>
\n example of how the vulnerability could be exploited using an HTTP request<\/a>:<\/p>\n

POST \/goform\/formSetWanNonLogin HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/x-www-form-urlencoded\ncurTime=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA...<\/code><\/pre>\n
In the above example, an excessively long ‘curTime’ argument is sent to the server, leading to a buffer<\/a> overflow.<\/p>\n
Mitigation and Recommendations<\/strong><\/p>\n
Affected users are advised to apply the vendor’s patch to correct this vulnerability. As this vulnerability affects<\/a> products that are no longer supported by the maintainer, users are encouraged to upgrade to a newer, supported version of the product. In the meantime, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used as a temporary mitigation strategy. These systems can detect and prevent exploitation attempts targeting this vulnerability<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
