The SOAP interface to the eMBox module in Novell eDirectory 188.8.131.52 and earlier, and 8.8.x before 8.8.2, relies on client-side authentication, which allows remote attackers to bypass authentication via requests for /SOAP URIs, and cause a denial of service (daemon shutdown) or read arbitrary files. NOTE: it was later reported that 184.108.40.206 (aka 8.7.3 SP10) is also affected.
CWE-287 - Improper Authentication
Improper (or broken) authentication attacks are widespread, and have accounted for many of the worst data breaches in recent years. Improper authentication attacks are a class of vulnerabilities where an attacker impersonates a legitimate user by exploiting weaknesses in either session management or credential management to gain access to the user’s account. This can result in disclosure of sensitive information, and can lead to system compromise, theft, identity theft, and fraud.
