Detailsinfo

A vulnerability was found in Circutor SGE-PLC1000 and SGE-PLC50 9.0.2. It has been classified as critical. This affects the function AddEvent. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Stack-based buffer overflow vulnerability in Circutor SGE-PLC1000/SGE-PLC50 v9.0.2. The vulnerability is found in the 'AddEvent()' function when copying the user-controlled username input to a fixed-size buffer (48 bytes) without boundary checking. This can lead to memory corruption, resulting in possible remote code execution.

The weakness was released by Gabriel Gonzalez and Sergio Ruiz. The advisory is shared at incibe.es. This vulnerability is uniquely identified as CVE-2025-11783 since 10/15/2025. The exploitability is told to be easy. The attack can only be done within the local network. Technical details are known, but no exploit is available.

Upgrading eliminates this vulnerability.
