CVE-2022-32261Network attack vector

Package integrity compromise via misconfigured APT updates

Published Jun 14, 2022 · Updated Aug 3, 2024

Improper parameter handling in Siemens SINEMA Remote Connect Server before 3.1 allows remote attackers to add insecure APT packages. The APT update configuration improperly handles update parameters, but Siemens has not disclosed the specific file, field, or validation failure. Network access without authentication is sufficient, and successful exploitation compromises the integrity of packages installed by the application.
