The Notes Remote Procedure Call (NRPC) protocol in IBM Lotus Notes Domino before 6.5.5 FP2 and 7.x before 7.0.2 does not require authentication to perform user lookups, which allows remote attackers to obtain the user ID file.

IBM Lotus Notes 6.5.4 and 6.5.5, and 7.0.0 and 7.0.1, uses insecure default permissions (Everyone/Full Control) for the "Notes" folder and all children, which allows local users to gain privileges and modify, add, or delete files in that folder.

IBM Lotus Notes before 6.5.6, and 7.x before 7.0.3; and Domino before 6.5.5 FP3, and 7.x before 7.0.2 FP1; uses weak permissions (Everyone:Full Control) for memory mapped files (shared memory) in IPC, which allows local users to obtain sensitive information, or inject Lotus Script or other character sequences into a session.

Cross-site scripting (XSS) vulnerability in the Active Content Filter feature in Domino Web Access (DWA) in IBM Lotus Notes before 6.5.6 and 7.x before 7.0.2 FP1 allows remote attackers to inject arbitrary web script or HTML via a multipart/related e-mail message, a different issue than CVE-2006-4843.
