CVE-2013-10064: ActFax 5.01 RAW Server Buffer Overflow
A stack-based buffer overflow vulnerability exists in ActFax Server version 5.01. The server's RAW protocol interface fails to safely process user-supplied data in @F506 fax header fields due to insecure usage of strcpy. Remote attackers can exploit this vulnerability by sending specially crafted @F506 fields, potentially leading to arbitrary code execution. Successful exploitation requires network access to TCP port 4559 and does not require authentication.
Security readout for executives and security teams
ActFax Server 5.01 has a critical flaw in its RAW fax interface. A remote, unauthenticated attacker with network access to TCP port 4559 could potentially run code on the server. Exposure is likely limited to legacy ActFax deployments, but any reachable instance should be treated urgently. Most likely exposure is legacy ActFax Server 5.01 systems where TCP port 4559 is reachable from untrusted networks or broad internal segments. The bundle does not establish exposure for other versions. Prioritize remediation wherever ActFax Server 5.01 is reachable. The business risk is highest where fax infrastructure touches sensitive workflows, because successful compromise could give attackers control of a trusted internal server. Mitigation focus: Identify any ActFax Server 5.01 deployments immediately.; Restrict TCP port 4559 to required trusted hosts only.; Check ActFax vendor guidance for supported updates or replacement advice..

Stack-based Buffer Overflow
Stack-based Buffer Overflow represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
