A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 3). The affected application does not properly invalidate sessions when the associated user is deleted or disabled or their permissions are modified. This could allow an authenticated attacker to continue performing malicious actions even after their user account has been disabled.

A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 3). The affected application does not properly validate input sent to specific endpoints of its web API. This could allow an authenticated remote attacker with high privileges on the application to execute arbitrary code on the underlying OS.

A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 3). The affected application uses hard-coded cryptographic key material to obfuscate configuration files. This could allow an attacker to learn that cryptographic key material through reverse engineering of the application binary and decrypt arbitrary backup files.

A vulnerability has been identified in SINEC INS (All versions < V1.0 SP2 Update 3). The affected application does not properly sanitize user provided paths for SFTP-based file up- and downloads. This could allow an authenticated remote attacker to manipulate arbitrary files on the filesystem and achieve arbitrary code execution on the device.

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*.
