SSA-077553: Multiple Vulnerabilities in Siemens License Server (SLS)
Notes
Summary: Siemens License Server is affected by multiple vulnerabilities which could allow an attacker to elevate its privileges and read arbitrary files on the system.
Siemens has released a new version for Siemens License Server (SLS) and recommends to update to the latest version.
General Recommendations: As a general security measure, Siemens strongly recommends to protect network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download: https://www.siemens.com/cert/operational-guidelines-industrial-security), and to follow the recommendations in the product manuals.
Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity
Additional Resources: For further inquiries on security vulnerabilities in Siemens products and solutions, please contact the Siemens ProductCERT: https://www.siemens.com/cert/advisories
Terms of Use: The use of Siemens Security Advisories is subject to the terms and conditions listed on: https://www.siemens.com/productcert/terms-of-use.
The affected application is vulnerable to a local privilege escalation due to an insecure sudoers policy. This could allow an attacker to execute arbitrary commands and plant malicious files as root, leading to full system compromise.
