A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 2). Affected software does not correctly validate the response received by an UMC server. An attacker can use this to crash the affected software by providing and configuring a malicious UMC server or by manipulating the traffic from a legitimate UMC server (i.e. leveraging CVE-2023-48427).

A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 2). The REST API of affected devices does not check the length of parameters in certain conditions. This allows a malicious admin to crash the server by sending a crafted request to the API. The server will automatically restart.

A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 2). Affected products do not properly validate the certificate of the configured UMC server. This could allow an attacker to intercept credentials that are sent to the UMC server as well as to manipulate responses, potentially allowing an attacker to escalate privileges.

When sending data to an MQTT server, libcurl <= 7.73.0 and 7.78.0 could in some circumstances erroneously keep a pointer to an already freed memory area and both use that again in a subsequent call to send data and also free it *again*.
