CVE-2023-24601Network attack vector

Session hijacking via arbitrary jslob registry references

Published May 29, 2023 · Updated Jan 14, 2025

Cross-site scripting in Open-Xchange OX App Suite frontend before 7.10.6-rev24 allows remote authenticated users to hijack sessions. The jslob API registry sub-tree accepts arbitrary module and dependency references from users, including references that load malicious code. Exploitation requires temporary account access or luring a victim to a compromised account; code runs in the victim's context and can trigger unwanted web or API actions.
