CVE-2024-2593Network attack vector

Session-cookie theft via unencoded b_id reflection

Published Mar 18, 2024 · Updated Aug 1, 2024

Cross-site scripting in AMSS++ 4.31 allows remote attackers to steal session cookies through a crafted b_id parameter. The bookdetail_group.php page places user-controlled b_id input into generated output without sufficient encoding. Exploitation requires an authenticated user to open the crafted URL, after which injected script runs in that user's browser context.
