A vulnerability in the admin/logbook.php code of Nagios XI could allow an unauthenticated, remote attacker to conduct a SQL injection attack on a targeted system.
The vulnerability is due to improper validation of user-supplied input by the affected software. An attacker could exploit this vulnerability by supplying crafted txtSearch parameters to a targeted system. An exploit could allow the attacker to perform a SQL injection attack, which could be used to conduct further attacks.
Proof-of-concept (PoC) code that demonstrates an exploit of this vulnerability is publicly available.
Nagios has not confirmed the vulnerability and software updates are not available.
To exploit this vulnerability, an attacker must send a malicious request to the targeted system, making exploitation more difficult in environments that restrict network access from untrusted sources.
Administrators are advised to contact the vendor regarding future updates and releases.
Administrators are advised to allow only trusted users to have network access.
Administrators are advised to run both firewall and antivirus applications to minimize the potential of inbound and outbound threats.
