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

The following report details a significant buffer overflow vulnerability discovered in Netis WF2880 v2.1.40207. This vulnerability, assigned the ID CVE-2025-50614, has the potential to impact any organization or individual utilizing this version of the Netis WF2880. Its exploitation can lead to a system crash, enabling a Denial of Service (DoS) attack and potentially compromising system security or leading to data leakage.<\/p>\n

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

CVE ID: CVE-2025-50614
\nSeverity: High (7.5 CVSS Score)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: No
\nImpact: Potential system compromise and data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

Netis WF2880 | v2.1.40207<\/p>\n

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

The vulnerability resides in the FUN_0047151c function of the cgitest.cgi file. Attackers can exploit this vulnerability by sending a specially crafted payload that controls the value of the wds_set variable. This causes a buffer overflow, leading to a program crash. If maliciously executed, this could potentially enable a Denial of Service (DoS) attack, thereby compromising the system or leading to data leakage.<\/p>\n

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

POST \/cgitest.cgi HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/x-www-form-urlencoded\nwds_set=OVERFLOW_VALUE<\/code><\/pre>\n
In the above conceptual example, the “OVERFLOW_VALUE” represents a payload that would cause a buffer overflow in the system.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
Users of the affected product are advised to apply the vendor patch as soon as it becomes available. Until then, the use of Web Application Firewall (WAF) or Intrusion Detection Systems (IDS) can provide temporary mitigation. Additionally, it’s recommended to regularly monitor system logs for any unusual activity that could indicate an attempt to exploit this vulnerability.<\/p>\n","protected":false},"excerpt":{"rendered":"
