A vulnerability has been identified in SCALANCE X-200 switch family (incl. SIPLUS NET variants) (All versions < V5.2.5), SCALANCE X-200IRT switch family (incl. SIPLUS NET variants) (All versions < V5.5.0). The vulnerability could allow an unauthenticated attacker to reboot the device over the network by using special urls from integrated web server of the affected products.

A vulnerability has been identified in SCALANCE X-200 switch family (incl. SIPLUS NET variants) (All versions < V5.2.5), SCALANCE X-200IRT switch family (incl. SIPLUS NET variants) (All versions < V5.5.0), SCALANCE X-200RNA switch family (All versions < V3.2.7). Devices create a new unique key upon factory reset, except when used with C-PLUG. When used with C-PLUG the devices use the hardcoded private RSA-key shipped with the firmware-image. An attacker could leverage this situation to a man-in-the-middle situation and decrypt previously captured traffic.

A vulnerability has been identified in SCALANCE X-200 switch family (incl. SIPLUS NET variants) (All versions < V5.2.5), SCALANCE X-200IRT switch family (incl. SIPLUS NET variants) (All versions < V5.5.0), SCALANCE X-300 switch family (incl. X408 and SIPLUS NET variants) (All versions < V4.1.0). The webserver of the affected devices contains a vulnerability that may lead to a heap overflow condition. An attacker could cause this condition on the webserver by sending specially crafted requests. This could stop the webserver temporarily.

A vulnerability has been identified in SCALANCE X-200IRT switch family (incl. SIPLUS NET variants) (All versions < V5.4.1), SCALANCE X-200RNA switch family (All versions < V3.2.7), SCALANCE X-300 switch family (incl. X408 and SIPLUS NET variants) (All versions < V4.1.3). A remote, authenticated attacker with access to the configuration web server could be able to store script code on the web site, if the HRP redundancy option is set. This code could be executed in the web browser of victims visiting this web site (XSS), affecting its confidentiality, integrity and availability. User interaction is required for successful exploitation, as the user needs to visit the manipulated web site. At the stage of publishing this security advisory no public exploitation is known. The vendor has confirmed the vulnerability and provides mitigations to resolve it.

A vulnerability has been identified in RFID 181EIP (All versions), RUGGEDCOM Win (V4.4, V4.5, V5.0, and V5.1), SCALANCE X-200 switch family (incl. SIPLUS NET variants) (All versions < V5.2.3), SCALANCE X-200IRT switch family (incl. SIPLUS NET variants) (All versions < V5.4.1), SCALANCE X-200RNA switch family (All versions < V3.2.6), SCALANCE X-300 switch family (incl. SIPLUS NET variants) (All versions < V4.1.3), SCALANCE X408 (All versions < V4.1.3), SCALANCE X414 (All versions), SIMATIC RF182C (All versions). Unprivileged remote attackers located in the same local network segment (OSI Layer 2) could gain remote code execution on the affected products by sending a specially crafted DHCP response to a client's DHCP request.

Specially crafted PROFINET DCP packets sent on a local Ethernet segment (Layer 2) to an affected product could cause a denial of service condition of that product. Human interaction is required to recover the system. PROFIBUS interfaces are not affected.

Specially crafted PROFINET DCP broadcast packets could cause a denial of service condition of affected products on a local Ethernet segment (Layer 2). Human interaction is required to recover the systems. PROFIBUS interfaces are not affected.

The authentication implementation in the web server on Siemens SCALANCE X-200 switches with firmware before 5.0.0 does not use a sufficient source of entropy for generating values of random numbers, which makes it easier for remote attackers to hijack sessions by predicting a value.

A vulnerability has been identified in SCALANCE X-200 switch family (incl. SIPLUS NET variants) (Versions < V5.0.0 for CVE-2013-3633 and versions < V4.5.0 for CVE-2013-3634), SCALANCE X-200IRT switch family (incl. SIPLUS NET variants) (All versions < V5.1.0). The user privileges for the web interface are only enforced on client side and not properly verified on server side. Therefore, an attacker is able to execute privileged commands using an unprivileged account.

A vulnerability has been identified in SCALANCE X-200 switch family (incl. SIPLUS NET variants) (Versions < V5.0.0 for CVE-2013-3633 and versions < V4.5.0 for CVE-2013-3634), SCALANCE X-200IRT switch family (incl. SIPLUS NET variants) (All versions < V5.1.0). The implementation of SNMPv3 does not check the user credentials sufficiently. Therefore, an attacker is able to execute SNMP commands without correct credentials.
