"text": "Siemens Automation License Manager contains two vulnerabilities which, when combined, could allow an attacker to modify and rename license files, extract licenses and overwrite arbitrary files on the target system potentially leading to privilege escalation and remote code execution. The affected functionality is not available for remote attackers in the default configuration since version V6.0 SP2 of Automation License Manager.\n\nSiemens has released an update for Automation License Manager V6 and recommends to update to the latest version. Siemens recommends specific countermeasures for products where updates are not, or not yet available.",
