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

The recently discovered CVE-2025-50753 vulnerability presents a significant security risk to all users of Mitrastar GPT-2741GNAC-N2 devices. These devices are equipped with a restricted shell access through ssh that is unfortunately not as restricted as it should be. This vulnerability is particularly dangerous because it allows unauthorized users to gain root shell access, potentially leading to system compromise or data<\/a> leakage. It’s critical to understand this vulnerability<\/a>, its potential impacts, and the necessary steps to mitigate it.<\/p>\n

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

CVE ID: CVE-2025-50753
\nSeverity: High (8.4)
\nAttack Vector: Network
\nPrivileges Required: Low
\nUser Interaction: None
\nImpact: System compromise, potential data<\/a> leakage<\/p>\n

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

The CVE-2025-50753 exploit involves the misuse of the “deviceinfo show file” command in the restricted shell<\/a> provided through ssh on Mitrastar GPT-2741GNAC-N2 devices. Normally, this command is used to display files<\/a> and directories. However, by providing ” \/bin\/sh” (including the quotes) as the argument to this command, an attacker can escape the restricted shell and gain access<\/a> to a root shell.<\/p>\n

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

In a typical ssh session, the exploit would look something like this:<\/p>\n

ssh user@target\npassword: \n<\/strong>\n\n$ deviceinfo show file \" \/bin\/sh\"\n# root shell access granted<\/code><\/pre>\n
In this example, `user@target` is the ssh login, and `
\n<\/strong>
\n` represents the user password<\/a>. The exploit itself is executed with the `deviceinfo show file<\/a> ” \/bin\/sh”` line.
\nWith this level of access, an attacker could perform a variety of malicious actions, including but not limited to, altering system files<\/a>, installing malicious software, or stealing sensitive data. This makes the CVE-2025-50753 vulnerability a high-risk<\/a> issue that must be addressed promptly.<\/p>\n
Mitigation<\/strong><\/p>\n
To protect your systems from this vulnerability<\/a>, apply the vendor patch as soon as it becomes available. In the meantime, you may use a Web Application Firewall (WAF) or Intrusion Detection System (IDS) as a temporary mitigation measure. Regularly monitor your systems for any unusual activity to detect potential<\/a> exploits at the earliest.<\/p>\n","protected":false},"excerpt":{"rendered":"
