Referensi Deskripsi

CVE-2002-2031

File existence via infoleak monitoring whether "onerror" handler fires or not.

CVE-2005-2025

Valid groupname enumeration via behavioral infoleak (sends response if valid, doesn't respond if not).

CVE-2001-1497

Behavioral infoleak in GUI allows attackers to distinguish between alphanumeric and non-alphanumeric characters in a password, thus reducing the search space.

CVE-2003-0190

Product immediately sends an error message when user does not exist instead of waiting until the password is provided, allowing username enumeration.

Mitigasi yang Memungkinkan

Phases : Requirements // Implementation
Phases : System Configuration // Implementation
For error pages, set up generic response pages for error conditions. The error page should not disclose information about the success or failure of a sensitive operation. For instance, the login page should not confirm that the login is correct and the password incorrect. The attacker who tries random account names may be able to guess some of them. Confirming that the account exists would make the login page more susceptible to brute force attack, or possibly leak information about the person who has the account.

Catatan Pemetaan Kerentanan

Justifikasi : This CWE entry is at the Variant level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.
Komentar : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
