The LINUXTCP port of FreeModbus contains an off-by-one bounds check in xMBPortTCPPool() (demo/LINUXTCP/port/porttcp.c). The check `if (usTCPFrameBytesLeft > MB_TCP_BUF_SIZE)` uses a strict greater-than comparison instead of greater-than-or-equal against the 263-byte MB_TCP_BUF_SIZE limit. An MBAP frame with a Length field of 264 makes usTCPFrameBytesLeft equal to 263, which passes the flawed check…

microtar's mtar_write_file_header() and mtar_write_dir_header() functions (src/microtar.c) copy a caller-supplied entry name into the 100-byte `name` field of a stack-allocated mtar_header_t via strcpy(h.name, name), with no check that strlen(name) is less than 100 before the copy. Any application that calls these functions with an externally-influenced filename longer than 99 characters (e.g. whe…

Vulnerabilidad crítica en nanoMODBUS v1.23.0: desbordamiento de búfer en servidor

nanoMODBUS hasta la versión 1.23.0 contiene un desbordamiento de búfer (out-of-bounds write) en la función handle_read_file_record() del servidor Modbus (FC 0x14). La validación de tamaño de solicitud es insuficiente, permitiendo que atacantes remotos causen escritura de memoria fuera de límites a través de múltiples sub-solicitudes acumulativas. Afecta infraestructuras SCADA, sistemas embebidos y dispositivos IoT industriales comunes en manufactura y utilidades de LATAM.

Vulnerabilidad crítica en nanoMODBUS v1.23.0: lectura fuera de límites en identificación de dispositivos

nanoMODBUS hasta la versión 1.23.0 contiene una vulnerabilidad de lectura fuera de los límites de la pila que permite escritura de punteros salvajes en la función nmbs_read_device_identification_basic(). Un campo object_id no validado (0-255) desde la red causa acceso a memoria no inicializada. Afecta sistemas SCADA, HMI y equipos IoT industriales en plantas manufactureras y servicios críticos de LATAM.

Inyección SQL crítica en Inventory-Management-System-PHP permite bypass de autenticación

El sistema de gestión de inventario PHP contiene vulnerabilidades de inyección SQL en los módulos login.php y delete.php debido a la concatenación insegura de parámetros POST sin validación ni uso de consultas parametrizadas. Un atacante puede ejecutar consultas arbitrarias, eludir la autenticación y manipular datos de inventario críticos en sistemas empresariales de LATAM que dependen de este software.

Inyección SQL crítica en Miantang/IoT-PHP permite autenticación sin credenciales válidas

La aplicación Miantang/IoT-PHP contiene una vulnerabilidad de inyección SQL en la ruta POST /userlogin debido a que no sanitiza el parámetro de contraseña antes de concatenarlo en una consulta SQL raw. Un atacante puede eludir la autenticación ingresando caracteres especiales en el campo de contraseña. Esta vulnerabilidad afecta sistemas IoT y aplicaciones embebidas en infraestructuras críticas de LATAM, permitiendo acceso no autorizado a datos sensibles y control del dispositivo.

Zbtlink router firmware ships an embedded remote-control implant, ENDLESSDOORS, present in every published build across the product line. It is the open-source ycsunjane/rctl tool built in as an OpenWrt package (librctl.so), started at boot and run as root under the process name kworker to blend in with the kernel's [kworker/*] threads. It opens no listening port; it phones home over cleartext TCP…

OpenSIPS is a Session Initiation Protocol (SIP) server implementation. In versions prior to 3.6.6 and 4.0.0-rc1, the construct_uri() function concatenates multiple URI components (protocol, username, domain, port, params) into a fixed 1024-byte global BSS buffer without any bounds checking. When a routing script calls construct_uri() with an attacker-controlled username, a combined component lengt…

OpenSIPS is a Session Initiation Protocol (SIP) server implementation. Versions 3.4.0-beta through 3.6.5 and 4.0.0-beta contain a buffer overflow in the {s.b64encode} string transformation. The size check for {s.b64encode} only verifies that the input fits within the 64 KB transformation buffer, but base64 encoding expands the data by roughly a third, so an input between about 49,153 and 65,535 by…
