CVE-2008-6797
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe server in Mitel NuPoint Messenger R11 and R3 sends usernames and passwords in cleartext to Exchange servers, which allows remote attackers to obtain sensitive information by sniffing the network.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceMitel NuPoint Messenger R11 and R3 transmits user credentials in cleartext to Exchange servers during authentication. An attacker positioned on the network path can intercept these credentials using packet sniffing. The vulnerability stems from the lack of encrypted communication channels between the NuPoint server and Exchange.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify NuPoint Messenger versionCheck the installed Mitel NuPoint Messenger version on the server or in the application properties. Common locations include the program's 'About' section, the installation directory, or registry entries under HKEY_LOCAL_MACHINE\SOFTWARE\Mitel\NuPoint.Affected if The installed version is specifically R3 or R11 (exact match to the affected versions listed).
-
Verify Exchange server connection configurationLocate the configuration settings that define how NuPoint Messenger connects to Exchange servers. Look for mail connector settings, typically found in the NuPoint administration console, configuration files, or registry under the mail/Exchange connection parameters.Affected if The connection to Exchange is configured without TLS/SSL encryption enabled, using plaintext protocols (such as port 25 without TLS or unencrypted LDAP).
-
Examine authentication settingsReview the authentication configuration between NuPoint and Exchange. Check whether the 'Basic Authentication' or unencrypted authentication methods are in use, and verify if secure authentication (NTLM, Kerberos, or TLS-based) is enforced.Affected if Authentication to Exchange is set to use plaintext credentials or unencrypted authentication mechanisms rather than encrypted channels.
-
Inspect network trafficUse a network packet capture tool (such as Wireshark) on the network segment between NuPoint and Exchange servers to observe the authentication exchange. Look for cleartext transmission of usernames and passwords.Affected if Packet captures reveal username and password fields sent in cleartext during the Exchange authentication process.
A system is affected if it runs NuPoint Messenger R3 or R11 AND the Exchange connection does not have TLS/SSL encryption enabled for authentication, resulting in cleartext credential transmission.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataEnable TLS/SSL encryption for all communications between Mitel NuPoint Messenger and Exchange servers, or apply vendor-provided patches that enforce encrypted authentication.
