CVE-2020-13229Public exploitNetwork attack vector

Session hijacking via reusable URL authentication token

Published Jun 2, 2020 · Updated Aug 4, 2024

Session hijacking in Sysax Multi Server 6.90 allows remote attackers to assume a logged-in user's session via an observed /scgi URL. The web interface places the sid authentication token in the /scgi query string and accepts the complete URL in another browser without a login. Access requires observation of a logged-in user's generated URI; reuse grants that user's authenticated web access.
