A vulnerability in the history.c file in Xymon could allow an unauthenticated, remote attacker to access or modify data, or cause a denial of service (DoS) condition on an affected system.
The vulnerability is due to a stack-based buffer overflow condition in the history.c file of the affected software. An attacker could exploit this vulnerability by submitting a long hostname or service parameter to the affected system. A successful exploit could allow the attacker to access or modify data, or cause a DoS condition on the affected system.
Xymon has confirmed the vulnerability and released a software update.
To exploit this vulnerability, the attacker must have network access to the targeted system. This requirement could reduce the likelihood of a successful exploit.
Administrators are advised to apply the appropriate updates.
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.
Administrators may consider using IP-based access control lists (ACLs)
to allow only trusted systems to access the affected systems.
Administrators can help protect affected systems from external attacks by using a solid firewall strategy.
Administrators are advised to monitor affected systems.
