FW-WGS-804HPT | v1.305b241111
How the Exploit Works
The exploit works by taking advantage of a stack overflow vulnerability in the web_tool_upgradeManager_post function of FW-WGS-804HPT v1.305b241111. Specifically, an attacker can overflow the stack by sending an excessively long string via the bytftp_srvip parameter. This could allow the attacker to execute arbitrary code or disrupt the normal functioning of the system.
Conceptual Example Code
The following example represents a potential exploitation attempt. This is a conceptual HTTP request that demonstrates how a malicious payload might be crafted.
POST /web_tool_upgradeManager_post HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "bytftp_srvip": "AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA..." }In this example, the “bytftp_srvip” parameter is filled with a long string of “A” characters. In a real attack, this string could contain malicious code designed to overflow the stack and compromise the system.
Mitigation
To mitigate this vulnerability, users are advised to apply the vendor-released patch as soon as possible. If immediate patching isn’t possible, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) could serve as temporary mitigation. These tools can help detect and prevent attempts to exploit this vulnerability. However, these are stop-gap measures and cannot substitute the necessity of applying the appropriate patches.
Remember, maintaining a robust cybersecurity posture necessitates regular software updates and security patch application. Regular audits and vulnerability scanning can also aid in identifying unpatched or vulnerable systems in your network.
