The SmartPoster implementation on the Nokia 6131 Near Field Communication (NFC) phone with 05.12 firmware does not properly display the URI record when the Title record contains a certain combination of space, CR (aka \r), and . (dot) characters, which allows remote attackers to trick a user into loading an arbitrary URI via a crafted NDEF tag, as demonstrated by (1) an http: URI for a malicious web site, (2) a tel: URI for a premium-rate telephone number, and (3) an sms: URI that triggers purchase of a ringtone.

The Nokia 6131 Near Field Communication (NFC) phone with 05.12 firmware automatically installs software upon completing the download of a JAR file, which makes it easier for remote attackers to execute arbitrary code via a crafted URI record in an NDEF tag.

The Nokia 6131 Near Field Communication (NFC) phone with 05.12 firmware allows remote attackers to cause a denial of service (device crash) via (1) a large value in the payload length field in an NDEF record, or a certain length for a (2) tel: or (3) sms: NDEF URI.
