47
FAUCET Score

CVE-2018-19246 describes a Local File Inclusion vulnerability in PHP-Proxy version 5.1.0, specifically impacting installations using the default "pre-installed version" configuration. This flaw arises from a hardcoded default app_key, which allows remote attackers to easily calculate authorization data and read arbitrary local files. With a CVSS score of 7.5 (HIGH), this vulnerability is easily exploitable over the network with low attack complexity, requiring no user interaction or privileges, and leading to high confidentiality impact. While not listed in CISA's KEV catalog, an ExploitDB entry (EDB-45861) confirms the existence of public exploit code, despite minimal community discussion or media coverage.
