Vulnerabilities

Sprecher Automations SPRECON-E series uses default cryptographic keys that allow an unprivileged remote attacker to access all encrypted communications, thereby compromising confidentiality and integrity.

Insufficient encryption strength in Sprecher Automation SPRECON-E-C, SPRECON-E-P, and SPRECON-E-T3 allows a local unprivileged attacker to extract data from update images and thus obtain limited information about the architecture and internal processes.

Sprecher Automations SPRECON-E-C, SPRECON-E-P, SPRECON-E-T3 is vulnerable to attack by an unauthorized remote attacker via default cryptographic keys. The use of these keys allows the attacker to read, modify, and write projects and data, or to access any device via remote maintenance.

Improper Privilege Management in Sprecher Automation SPRECON-E below version 8.71j allows a remote attacker with low privileges to save unauthorized protection assignments.

Hardcoded Credentials in multiple SPRECON-E CPU variants of Sprecher Automation allows an remote attacker to take over the device. These accounts should be deactivated according to Sprecher's hardening guidelines.

In Sprecher Automation SPRECON-E-C/P/T3 CPU in variant PU244x a vulnerable firmware verification has been identified. Through physical access and hardware manipulation, an attacker might be able to bypass hardware-based code verification and thus inject and execute arbitrary code and gain full access of the device.

Sprecher SPRECON-E firmware prior to 8.64b might allow local attackers with access to engineering data to insert arbitrary code. This firmware lacks the validation of the input values on the device side, which is provided by the engineering software during parameterization. Attackers with access to local configuration…

An issue was discovered in Sprecher Automation SPRECON-E Service Program before 3.43 SP0. Under certain preconditions, it is possible to execute telegram simulation as a non-admin user. As prerequisites, a user must have created an online-connection, validly authenticated and authorized as administrator, and executed…
