CVE-2023-36917Network attack vector

Account takeover via unrestricted old-password guessing

Published Jul 11, 2023 · Updated Oct 23, 2024

Authentication bypass in SAP BusinessObjects Business Intelligence Platform 4.20 and 430 allows remote attackers to take over a hijacked user account. The password-change function imposes no rate limit on guesses of the victim's old password, allowing brute-force bypass of that confirmation step. A valid hijacked user session is required; the documented consequence is complete account takeover without integrity or availability impact.
