CVE-2022-27503Network attack vector

Client-side script execution via reflected XSS

Published Apr 13, 2022 · Updated Aug 3, 2024

Reflected XSS in Citrix StoreFront 1912 before CU5 and 3.12 before CU9 allows remote attackers to run JavaScript in a user's browser. Citrix has not disclosed the reflected parameter or the code path that fails to neutralize it. Exploitation requires SAML authentication, a victim with a current StoreFront session, and interaction with the attack mechanism; the script runs in that user's context.
