CVE-2026-8450

HTTP::Daemon versions before 6.17 for Perl allow OS command injection via send_file() PUBLISHED

Description (CNA)

HTTP::Daemon versions before 6.17 for Perl allow OS command injection via send_file(). send_file() opens its string argument with Perl's 2-arg open(). The 2-arg form interprets magic prefixes: '| cmd' and 'cmd |' open a pipe to a subprocess, '> path' and '>> path' open the path for write or append. Untrusted input passed to send_file() can run OS commands at the daemon process UID. The read-pipe form ('cmd |') also leaks subprocess stdout into the HTTP response body. The write-mode forms can create or truncate files at attacker chosen paths.

A flaw was found in HTTP::Daemon, a Perl module used for creating HTTP servers. A remote attacker can exploit this vulnerability by providing specially crafted input to the `send_file()` function, leading to OS command injection. This allows the attacker to execute arbitrary commands on the system with the privileges of the daemon process, potentially resulting in full system compromise or data manipulation.
