| VAR-202512-1306 | CVE-2025-11784 |
CVSS V2: - CVSS V3: 9.8 Severity: CRITICAL |
Stack-based buffer overflow vulnerability in Circutor SGE-PLC1000/SGE-PLC50 v9.0.2. In the 'ShowMeterDatabase()' function, there is an unlimited user input that is copied to a fixed-size buffer via 'sprintf()'. The 'GetParameter(meter)' function retrieves the user input, which is directly incorporated into a buffer without size validation. An attacker can provide an excessively large input for the 'meter' parameter.
| VAR-202512-1045 | CVE-2025-11783 |
CVSS V2: - CVSS V3: 9.8 Severity: CRITICAL |
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.
| VAR-202512-4596 | CVE-2025-11782 |
CVSS V2: - CVSS V3: 9.8 Severity: CRITICAL |
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.
| VAR-202512-0794 | CVE-2025-11781 |
CVSS V2: - CVSS V3: 7.8 Severity: HIGH |
Use of hardcoded cryptographic keys in Circutor SGE-PLC1000/SGE-PLC50 v9.0.2. The affected firmware contains a hardcoded static authentication key. An attacker with local access to the device can extract this key (e.g., by analysing the firmware image or memory dump) and create valid firmware update packages. This bypasses all intended access controls and grants full administrative privileges.
| VAR-202512-5314 | CVE-2025-11780 |
CVSS V2: - CVSS V3: 9.8 Severity: CRITICAL |
Stack-based buffer overflow vulnerability in Circutor SGE-PLC1000/SGE-PLC50 v9.0.2. In the 'showMeterReport()' function, there is an unlimited user input that is copied to a fixed-size buffer via 'sprintf()'. The 'GetParameter(meter)' function retrieves the user input, which is directly incorporated into a buffer without size validation. An attacker can provide an excessively large input for the “meter” parameter.
| VAR-202512-1580 | CVE-2025-11779 |
CVSS V2: - CVSS V3: 9.8 Severity: CRITICAL |
Stack-based buffer overflow vulnerability in CircutorSGE-PLC1000/SGE-PLC50 v9.0.2. The 'SetLan' function is invoked when a new configuration is applied. This new configuration function is activated by a management web request, which can be invoked by a user when making changes to the 'index.cgi' web application. The parameters are not being sanitised, which could lead to command injection.
| VAR-202512-4327 | CVE-2025-11778 |
CVSS V2: - CVSS V3: 9.8 Severity: CRITICAL |
Stack-based buffer overflow in Circutor SGE-PLC1000/SGE-PLC50 v0.9.2. This vulnerability allows an attacker to remotely exploit memory corruption through the 'read_packet()' function of the TACACSPLUS implementation.
| VAR-202512-2040 | CVE-2025-20792 |
CVSS V2: - CVSS V3: 5.3 Severity: MEDIUM |
In Modem, there is a possible system crash due to improper input validation. This could lead to remote denial of service, if a UE has connected to a rogue base station controlled by the attacker, with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: MOLY01717526; Issue ID: MSV-5591.
| VAR-202512-1517 | CVE-2025-20791 |
CVSS V2: - CVSS V3: 5.3 Severity: MEDIUM |
In Modem, there is a possible system crash due to incorrect error handling. This could lead to remote denial of service, if a UE has connected to a rogue base station controlled by the attacker, with no additional execution privileges needed. User interaction is not needed for exploitation. Patch ID: MOLY01661189; Issue ID: MSV-4298.
