REJECT DO NOT USE THIS CANDIDATE NUMBER. ConsultIDs: None. Reason: this candidate is solely about a configuration that does not directly introduce security vulnerabilities, so it is more appropriate to cover under the Common Configuration Enumeration (CCE). Notes: the former description is: "A POP service is running." This Common Vulnerabilities and Exposures (CVE) entry is a configuration issue and not a software flaw. As such, it doesn’t fit in the CVE software flaw list. The Common Vulnerability Scoring System (CVSS) base score for this CVE entry has been set to 0 because this CVE entry has no impact as a software flaw according to CVSS. This does not mean that the configuration issue is not important and there may be security implications relative to computers having this configuration. POP3 is an unsecured protocol for Internet facing systems that does not encrypt its transmissions. POP3 should be tunneled over SSL/TLS or another encrypted tunnel. The software should be patched and configured properly. Earlier versions of POP, such as POP2, are unsecured and obsolete, and should be disabled.
