CVE Microsoft Exchange

AV Option for MS Exchange Server option for InoculateIT 4.53, and possibly other versions, only scans the Inbox folder tree of a Microsoft Exchange server, which could allow viruses to escape detection if a user's rules cause the message to be moved to a different mailbox.

Microsoft Exchange Server 5.5 and 5.0 does not properly handle (1) malformed NNTP data, or (2) malformed SMTP data, which allows remote attackers to cause a denial of service (application error).

Microsoft Exchange Server 5.5 does not properly handle a MIME header with a blank charset specified, which allows remote attackers to cause a denial of service via a charset="" command, aka the "Malformed MIME Header" vulnerability.

An interaction between the Outlook Web Access (OWA) service in Microsoft Exchange 2000 Server and Internet Explorer allows attackers to execute malicious script code against a user's mailbox via a message attachment that contains HTML code, which is executed automatically.

Vulnerabilities in RPC servers in (1) Microsoft Exchange Server 2000 and earlier, (2) Microsoft SQL Server 2000 and earlier, (3) Windows NT 4.0, and (4) Windows 2000 allow remote attackers to cause a denial of service via malformed inputs.

Outlook Web Access (OWA) in Microsoft Exchange 5.5 Server, when used with Internet Explorer, does not properly detect certain inline script, which can allow remote attackers to perform arbitrary actions on a user's Exchange mailbox via an HTML e-mail message.

Microsoft Exchange Server 2000 System Attendant gives "Everyone" group privileges to the WinReg key, which could allow remote attackers to read or modify registry keys.

SMTP service in (1) Microsoft Windows 2000 and (2) Internet Mail Connector (IMC) in Exchange Server 5.5 does not properly handle responses to NTLM authentication, which allows remote attackers to perform mail relaying via an SMTP AUTH command using null session credentials.

The keep-alive mechanism for Microsoft SQL Server 2000 allows remote attackers to cause a denial of service (bandwidth consumption) via a "ping" style packet to the Resolution Service (UDP port 1434) with a spoofed IP address of another SQL Server system, which causes the two servers to exchange packets in an infinite loop.

Buffer overflow in Internet Mail Connector (IMC) for Microsoft Exchange Server 5.5 allows remote attackers to execute arbitrary code via an EHLO request from a system with a long name as obtained through a reverse DNS lookup, which triggers the overflow in IMC's hello response.

Microsoft Outlook 2002 does not properly handle requests to encrypt email messages with V1 Exchange Server Security certificates, which causes Outlook to send the email in plaintext, aka "Flaw in how Outlook 2002 handles V1 Exchange Server Security Certificates could lead to Information Disclosure."

Cross-site scripting (XSS) vulnerability in the HTML encoding for the Compose New Message form in Microsoft Exchange Server 5.5 Outlook Web Access (OWA) allows remote attackers to execute arbitrary web script.

The Content Scanner Server in F-Secure Anti-Virus for Microsoft Exchange 6.21 and earlier, F-Secure Anti-Virus for Microsoft Exchange 6.01 and earlier, and F-Secure Internet Gatekeeper 6.32 and earlier allow remote attackers to cause a denial of service (service crash due to unhandled exception) via a certain malformed packet.

Network Dynamic Data Exchange (NetDDE) services for Microsoft Windows 98, Windows NT 4.0, Windows 2000, Windows XP, and Windows Server 2003 allows attackers to remotely execute arbitrary code or locally gain privileges via a malicious message or application that involves an "unchecked buffer," possibly a buffer overflow.

The Network News Transfer Protocol (NNTP) component of Microsoft Windows NT Server 4.0, Windows 2000 Server, Windows Server 2003, Exchange 2000 Server, and Exchange Server 2003 allows remote attackers to execute arbitrary code via XPAT patterns, possibly related to improper length validation and an "unchecked buffer," leading to off-by-one and heap-based buffer overflows.

The SMTP (Simple Mail Transfer Protocol) component of Microsoft Windows XP 64-bit Edition, Windows Server 2003, Windows Server 2003 64-bit Edition, and the Exchange Routing Engine component of Exchange Server 2003, allows remote attackers to execute arbitrary code via a malicious DNS response message containing length values that are not properly validated.

Stack consumption vulnerability in Microsoft Exchange Server 2003 SP1 allows users to cause a denial of service (hang) by deleting or moving a folder with deeply nested subfolders, which causes Microsoft Exchange Information Store service (Store.exe) to hang as a result of a large number of recursive calls.

Cross-site scripting (XSS) vulnerability in Microsoft Outlook Web Access (OWA) component in Exchange Server 5.5 allows remote attackers to inject arbitrary web script or HTML via an email message with an encoded javascript: URL ("jav&#X41sc
ript:") in an IMG tag.

Buffer overflow in Collaboration Data Objects (CDO), as used in Microsoft Windows and Microsoft Exchange Server, allows remote attackers to execute arbitrary code when CDOSYS or CDOEX processes an e-mail message with a large header name, as demonstrated using the "Content-Type" string.

Unspecified vulnerability in Microsoft Outlook 2000 through 2003, Exchange 5.0 Server SP2 and 5.5 SP4, Exchange 2000 SP3, and Office allows remote attackers to execute arbitrary code via an e-mail message with a crafted Transport Neutral Encapsulation Format (TNEF) MIME attachment, related to message length validation.
