Multiple stack-based buffer overflows in CMailCOM.dll in CMailServer 5.4.6 allow remote attackers to execute arbitrary code via a long argument to the (1) CreateUserPath, (2) Logout, (3) DeleteMailByUID, (4) MoveToInbox, (5) MoveToFolder, (6) DeleteMailEx, (7) GetMailDataEx, (8) SetReplySign, (9) SetForwardSign, and (10) SetReadSign methods, which are not properly handled by (a) the POP3 Class ActiveX control (CMailCom.POP3); or a long argument to the (11) AddAttach, (12) SetSubject, (13) SetBcc, (14) SetBody, (15) SetCc, (16) SetFrom, (17) SetTo, and (18) SetFromUID methods, which are not properly handled by the Class ActiveX control (CMailCOM.SMTP), as demonstrated via the indexOfMail parameter to mwmail.asp.

Security readout for executives and security teams

CMailServer 5.4.6 contains multiple memory-safety flaws in CMailCOM.dll. A remote attacker could supply oversized input to affected mail-related functions and potentially run code on the server. This is legacy software, but any exposed deployment should be treated as serious because the source bundle includes a public exploit reference. Exposure is most likely where CMailServer 5.4.6, CMailCOM.dll, or mwmail.asp remains deployed and reachable by untrusted users. The bundle does not identify other affected versions or products. Prioritize quickly if this legacy mail server is internet-facing or supports business-critical mail. The business risk is remote code execution on a mail system, but urgency depends on whether CMailServer 5.4.6 is still deployed. Mitigation focus: Check vendor or trusted advisory guidance for fixed versions or official workarounds.; Retire or replace CMailServer 5.4.6 if no supported fix is available.; Restrict access to mwmail.asp and affected mail interfaces to trusted networks..
