AI description
CVE-2025-10948 is a buffer overflow vulnerability found in MikroTik RouterOS 7. Specifically, the flaw resides within the `parse_json_element` function of the `libjson.so` shared library. This vulnerability is triggered by insufficient bounds checking when the system processes JSON input. Remote attackers can exploit this by sending a specially crafted JSON payload to the `/rest/ip/address/print` REST API endpoint. This malicious input causes the `parse_json_element` function to write data beyond its allocated buffer, corrupting adjacent memory regions. The vulnerability is classified under CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-120 (Buffer Copy without Checking Size of Input).
