Detailsinfo

A vulnerability was found in Circutor SGE-PLC1000 and SGE-PLC50 9.0.2 and classified as critical. This issue affects the function ShowDownload. The manipulation of the argument meter with an unknown input leads to a stack-based overflow vulnerability. Using CWE to declare the problem leads to 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). Impacted is confidentiality, integrity, and availability. The summary by CVE is:

Stack-based buffer overflow vulnerability in Circutor SGE-PLC1000/SGE-PLC50 v9.0.2. The 'ShowDownload()' function uses “sprintf()” to format a string that includes the user-controlled input of 'GetParameter(meter)' in the fixed-size buffer 'acStack_4c' (64 bytes) without checking the length. An attacker can provide an excessively long value for the 'meter' parameter that exceeds the 64-byte buffer size.

The weakness was shared by Gabriel Gonzalez and Sergio Ruiz. The advisory is shared at incibe.es. The identification of this vulnerability is CVE-2025-11782 since 10/15/2025. The exploitation is known to be easy. The attack can only be initiated within the local network. Technical details are known, but no exploit is available.

Upgrading eliminates this vulnerability.

The vulnerability is also documented in the vulnerability database at EUVD (EUVD-2025-200234). Several companies clearly confirm that VulDB is the primary source for best vulnerability data.
