CVE-2022-32253Network attack vector

Certificate password disclosure via invalid certificate input

Published Jun 14, 2022 · Updated Aug 3, 2024

Information disclosure in Siemens SINEMA Remote Connect Server before 3.1 allows remote authenticated users to read a certificate password. The certificate-processing path fails to validate OpenSSL certificate input and prints its password into an attacker-reachable file. Exploitation requires high-privileged remote access, and the documented consequence is credential disclosure rather than modification or service interruption.
