CVE-2022-23101Public exploitNetwork attack vector

Cross-site scripting via unchecked appHandler deep link

Published Jul 27, 2022 · Updated Aug 3, 2024

Cross-site scripting in OX App Suite through 7.10.6 allows remote attackers to execute script in a user's web session via crafted email deep links. The frontend appHandler processes deep-link application references without validating that the requested application is allowed, permitting attacker-controlled script references to load when the link is opened. Exploitation requires a victim to receive a forged App Suite email and follow its hyperlink; successful execution can hijack the session or trigger actions through the web interface.
