CVE-2001-1088 : Détail

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

source: https://www.securityfocus.com/bid/2823/info Outlook Express is the standard e-mail client that is shipped with Microsoft Windows 9x/ME/NT. The address book in Outlook Express is normally configured to make entries for all addresses that are replied to by the user of the mail client. An attacker may construct a message header that tricks Address Book into making an entry for an untrusted user under the guise of a trusted one. This is done by sending a message with a misleading "From:" field. When the message is replied to then Address Book will make an entry which actually replies to the attacker. Situation: 2 good users Target1 and Target2 with addresses target1@example.com and target2@example.com and one bad user Attacker, attacker@example.com. Imagine Attacker wants to get messages Target1 sends to Target2. Scenario: 1. Attacker composes message with headers: From: "target2@example.com" <attacker@example.com> Reply-To: "target2@example.com" <attacker@example.com> To: Target1 <target1@example.com> Subject: how to catch you on Friday? and sends it to target1@example.com 2. Target1 receives mail, which looks absolutely like mail received from target2@example.com and replies it. Reply will be received by Attacker. In this case new entry is created in address book pointing NAME "target2@example.com" to ADDRESS attacker@example.com. 3. Now, if while composing new message Target1 directly types e-mail address target2@example.com instead of Target2, Outlook will compose address as "target2@example.com" <attacker@example.com> and message will be received by Attacker.
