CVE-2006-1948: IBM Lotus Notes

Medium severity, CVSS 4.0. EPSS: 1% chance of exploitation in the next 30 days.

The "Add Sender to Address Book" operation (AddSenderToAddressBook.lss) and NameHelper.lss in IBM Lotus Notes 6.0 and 6.5 before 20060331 do not properly store information in the Personal Address Book when multiple messages are checked and a message uses AltFrom, which might allow user-assisted remote attackers to trick a user into sending e-mail to an unauthorized recipient.

Affected products

• IBM Lotus Notes: version 6.0 only; version 6.5 only
