Vulnerability from variot

A vulnerability has been identified in Firmware variant PROFINET IO for EN100 Ethernet module : All versions < V1.04.01; Firmware variant Modbus TCP for EN100 Ethernet module : All versions < V1.11.00; Firmware variant DNP3 TCP for EN100 Ethernet module : All versions < V1.03; Firmware variant IEC 104 for EN100 Ethernet module : All versions < V1.21; EN100 Ethernet module included in SIPROTEC Merging Unit 6MU80 : All versions < 1.02.02. The integrated web server (port 80/tcp) of the affected devices could allow remote attackers to obtain a limited amount of device memory content if network access was obtained. This vulnerability only affects EN100 Ethernet module included in SIPROTEC4 and SIPROTEC Compact devices. SiemensSIPROTEC4 is a multi-function relay series; SIPROTECCompact is a microcomputer protection device. An information disclosure vulnerability exists in the integrated web server of SIPROTEC4 and SIPROTECCompact. EN100 Ethernet Modules for Reyrolle is prone to the following security vulnerabilities: : 1. Multiple information-disclosure vulnerabilities 2. A denial-of-service vulnerability 3. Multiple authentication-bypass vulnerabilities An attacker may leverage these issues to disclose sensitive information, perform certain unauthorized actions actions, gain unauthorized access, or bypass certain security restrictions and cause a denial-of-service condition. Both Siemens SIPROTEC 4 and SIPROTEC Compact are products of Siemens, Germany. Siemens SIPROTEC 4 is a series of multifunctional relays with a friendly man-machine interface. EN100 is one of the multi-format encoder modules

The integrated web server (port 80/tcp) of the affected devices could allow remote attackers to obtain a limited amount of device memory content if network access was obtained. This vulnerability only affects EN100 Ethernet module included in SIPROTEC4 and SIPROTEC Compact devices. SiemensSIPROTEC4 is a multi-function relay series; SIPROTECCompact is a microcomputer protection device. An information disclosure vulnerability exists in the integrated web server of SIPROTEC4 and SIPROTECCompact. EN100 Ethernet Modules for Reyrolle is prone to the following security vulnerabilities: :\n1. Multiple information-disclosure vulnerabilities\n2. A denial-of-service vulnerability\n3. Multiple authentication-bypass vulnerabilities\nAn attacker may leverage these issues to disclose sensitive information, perform certain unauthorized actions actions, gain unauthorized access, or bypass certain security restrictions and cause a denial-of-service condition. Both Siemens SIPROTEC 4 and SIPROTEC Compact are products of Siemens, Germany. Siemens SIPROTEC 4 is a series of multifunctional relays with a friendly man-machine interface. EN100 is one of the multi-format encoder modules",
