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

In the constantly evolving world of cybersecurity, new vulnerabilities are discovered regularly. One such vulnerability has recently been identified in the FW-WGS-804HPT v1.305b241111, coded as CVE-2025-44883. This vulnerability is of particular concern due<\/a> to its severity and the potential for system compromise or data leakage.
\nUsers of FW-WGS-804HPT v1.305b241111 should pay special attention to this vulnerability, as it allows attackers to exploit a stack overflow<\/a> via the tacIp parameter in the web_tacplus_serverEdit_post function. This could lead to unauthorized<\/a> access, disruption of services, or worse, extraction of sensitive data.<\/p>\n

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

CVE ID: CVE-2025-44883
\nSeverity: Critical (9.8 CVSS Score)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise and potential<\/a> data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

FW-WGS-804HPT | v1.305b241111<\/p>\n

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

The vulnerability is a stack overflow<\/a> issue that can be triggered by an attacker sending a specially crafted packet to the targeted system. This packet contains an overly long string in the ‘tacIp’ parameter in the web_tacplus_serverEdit_post function.
\nThe function fails to properly validate and sanitize this input<\/a>, which can overwrite the stack buffer. This opens up the potential for arbitrary code execution<\/a>, which can lead to full system compromise.<\/p>\n

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

Here is a conceptual example of how the vulnerability might be exploited. This represents a malicious HTTP POST request<\/a> that sends an overly long string in the ‘tacIp’ field:<\/p>\n

POST \/web_tacplus_serverEdit_post HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/x-www-form-urlencoded\ntacIp=AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA... (continued until buffer overflow)<\/code><\/pre>\n
In this example, ‘AAAAAAAA…’ represents the overly long string that overflows the stack buffer<\/a>.
\nPlease note, this example is purely conceptual and is meant to illustrate how an attacker might exploit the vulnerability<\/a>. It is not intended to be used as an actual attack.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
To mitigate this vulnerability, users are advised to apply the vendor-supplied patch as soon as possible. If this is not feasible or until the patch can be applied, the use of a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure, detecting and blocking attempts to exploit this vulnerability<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
