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

A critical vulnerability has been found in MikroTik RouterOS 7, a popular operating system for routers. This vulnerability, cataloged as CVE-2025-10948, significantly impacts the router’s functionality, potentially leading to system compromise or data leakage. As routers are often the first line of defense in a network, this vulnerability could potentially<\/a> expose a network and its users to various forms of cyber-attacks, including unauthorized access, data theft, and Denial of Service (DoS) attacks.<\/p>\n

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

CVE ID: CVE-2025-10948
\nSeverity: High (CVSS: 8.8)
\nAttack Vector: Network
\nPrivileges Required: None
\nUser Interaction: None
\nImpact: System compromise<\/a>, potential data leakage<\/p>\n

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

Product | Affected Versions<\/p>\n

MikroTik | RouterOS 7<\/p>\n

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

The vulnerability lies in the function parse_json_element of the file<\/a> \/rest\/ip\/address\/print of the component libjson.so in MikroTik RouterOS. An attacker can manipulate data that leads to a buffer overflow<\/a> condition. As a result, attackers can remotely execute<\/a> arbitrary code on the affected system, potentially compromising the system or leading to data leakage.<\/p>\n

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

Below is a conceptual example demonstrating how the vulnerability might be exploited. This example involves sending a malicious HTTP request to the vulnerable<\/a> endpoint:<\/p>\n

POST \/rest\/ip\/address\/print HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/json\n{ \"overflow\": \"AAAAA....[continued until buffer overflow]\" }<\/code><\/pre>\n
In the above example, the ‘overflow’ field contains an artificially long string of ‘A’s designed to overflow the buffer, potentially leading to arbitrary code execution<\/a>.<\/p>\n
Mitigation Guidance<\/strong><\/p>\n
The best course of action to mitigate this vulnerability<\/a> is to apply the vendor patch as soon as it is available. In the case where the vendor has not provided a patch or the patching is not immediately feasible, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. It is crucial to regularly update and patch all systems to ensure the highest level of security<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
