CVE-2012-1496Network attack vector

Authenticated local file access via undisclosed inclusion flaw

Published Jan 27, 2020 · Updated Aug 6, 2024

Local file inclusion in WebCalendar before 1.2.5 allows remote authenticated users to read local files through network requests. Public records do not identify the vulnerable script, parameter, or file-inclusion operation that accepts attacker-controlled input. Exploitation requires a valid low-privilege account, and successful requests expose files readable by the web server process.
