CVE-2023-45196Network attack vector

Service interruption via automatic HTTP redirects

Published Jun 24, 2024 · Updated Aug 2, 2024

Resource exhaustion in Adminer and in AdminerEvo before 4.8.4 allows remote attackers to interrupt service through crafted HTTP redirects. The Elasticsearch, ClickHouse, and SimpleDB drivers use file_get_contents with PHP's default redirect following, letting a hostile endpoint force repeated requests. The unauthenticated login path must connect to an attacker-controlled service, and resource consumption is bounded by PHP configuration limits.
