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

The digital world is increasingly becoming a playground for cybercriminals, and with this comes the urgent need to shed light on potential system vulnerabilities. This blog post focuses on the critical vulnerability found in D-Link DIR-619L 2.06B01, identified as CVE-2025-6374. This issue affects<\/a> the function formSetACLFilter of the file \/goform\/formSetACLFilter. It is a matter of significant concern due to its critical<\/a> severity rating and the potential for remote initiation of an exploit, leading to system compromise or data leakage.<\/p>\n

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

CVE ID: CVE-2025-6374
\nSeverity: Critical (8.8 CVSS Score)
\nAttack Vector: Remote (Network)
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: Potential system<\/a> compromise or data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

D-Link DIR-619L | 2.06B01<\/a><\/p>\n

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

The vulnerability lies within the formSetACLFilter function of the file<\/a> \/goform\/formSetACLFilter. The improper handling of the ‘curTime’ argument leads to a stack-based buffer overflow<\/a>. This overflow can be manipulated remotely<\/a>, leading to potential system compromise or data leakage. The exploit has been disclosed publicly, increasing the risk of its usage by malicious actors.<\/p>\n

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

The below pseudocode illustrates how an attacker might exploit this vulnerability<\/a>:<\/p>\n

POST \/goform\/formSetACLFilter HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/x-www-form-urlencoded\ncurTime=AAAAAAAA... (a long string that triggers the stack-based buffer overflow)<\/code><\/pre>\n
In the above code, the ‘curTime’ parameter is given a long string of ‘A’s that could potentially overflow the stack buffer<\/a>, leading to the execution of arbitrary code or crashing the system.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
Due to the critical nature of this vulnerability<\/a>, it is essential to take mitigation steps immediately. If a vendor patch is available, it should be applied without delay. If no patch is available, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can offer temporary mitigation. However, note that this vulnerability affects products<\/a> that are no longer supported by the manufacturer, highlighting the importance of keeping software and devices up-to-date and maintained.<\/p>\n","protected":false},"excerpt":{"rendered":"
