CVE-2005-3539: Multiple eval injection vulnerabilities in HylaFAX 4.2.3 and earlier allow remote attackers to execute arbi...

Security readout for executives and security teams

HylaFAX 4.2.3 and earlier contains eval injection flaws that can let a remote attacker execute commands through fax notification or received-fax handling scripts. This is serious for any remaining legacy HylaFAX deployment, but the supplied sources do not show active exploitation or a CVSS score. Exposure is most likely in legacy fax servers running HylaFAX 4.2.3 or earlier, especially systems still processing inbound fax events or notification scripts. Modern systems are only exposed if they retain these old packages or embedded copies. Prioritize remediation if HylaFAX is still used in production or reachable from untrusted inputs. The business risk is legacy remote command execution in a fax workflow, with no supplied evidence of current mass exploitation. Mitigation focus: Upgrade HylaFAX to 4.2.4 or a vendor package containing the security fix.; Review Debian, Gentoo, Mandriva, or relevant distribution advisories for packaged fixes.; Retire unsupported HylaFAX 4.2.3 and earlier instances where possible..
