The webserver of the affected products contains a vulnerability that may lead to a denial of service condition. An attacker may cause a denial of service situation which leads to a restart of the webserver of the affected product.

Affected devices don't process correctly certain special crafted packets sent to port 102/tcp, which could allow an attacker to cause a denial of service in the device.

Affected devices don't process correctly certain special crafted packets sent to port 102/tcp, which could allow an attacker to cause a denial of service in the device.

A flaw was found in multiple versions of OpenvSwitch. Specially crafted LLDP packets can cause memory to be lost when allocating data to handle specific optional TLVs, potentially causing a denial of service. The highest threat from this vulnerability is to system availability.

The webserver of the affected devices contains a vulnerability that may lead to a denial of service condition. An attacker may cause a denial of service situation which leads to a restart of the webserver of the affected device. The security vulnerability could be exploited by an attacker with network access to the affected systems. Successful exploitation requires no system privileges and no user interaction. An attacker could use the vulnerability to compromise availability of the device.

A vulnerability has been identified in TIM 1531 IRC (All version < V2.0). The devices was missing proper authentication on port 102/tcp, although configured. Successful exploitation requires an attacker to be able to send packets to port 102/tcp of the affected device. No user interaction and no user privileges are required to exploit the vulnerability. At the time of advisory publication no public exploitation of this vulnerability was known.

A vulnerability has been identified in TIM 1531 IRC (All versions < V1.1). A remote attacker with network access to port 80/tcp or port 443/tcp could perform administrative operations on the device without prior authentication. Successful exploitation could allow to cause a denial-of-service, or read and manipulate data as well as configuration settings of the affected device. At the stage of publishing this security advisory no public exploitation is known. Siemens provides mitigations to resolve it.
