名前: Use of Password Hash Instead of Password for Authentication
The product includes a client that computes a hash of a password and sends the hash to another component, which compares the supplied hash to the hash obtained from a data store of password hashes.
一般情報
導入モード
Implementation : REALIZATION: This weakness is caused during implementation of an architectural security tactic.Architecture and Design : Some authentication mechanisms rely on the client to generate the hash for a password, possibly to reduce load on the server or avoid sending the password across the network.

|---|---|---|
| Access Control Authentication | Bypass Protection Mechanism, Gain Privileges or Assume Identity 注記：An attacker could bypass the authentication routine without knowing the original password. The attacker could obtain a copy of the hash (e.g., through a separate weakness against a database of authentication credentials), then use a modified client to replay the stolen hash. As a result, the server-side comparison against a client-side hash does not provide any more security than the use of passwords without hashing. |

| 参考文献 | 説明 |
|---|---|
CVE-2009-1283 | Product performs authentication with user-supplied password hashes that can be obtained from a separate SQL injection vulnerability (CVE-2009-1282). |
CVE-2005-3435 | Product allows attackers to bypass authentication by obtaining the password hash for another user and specifying the hash in the pwd argument. |
脆弱性マッピングノート
理由 : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.コメント : 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.

| CAPEC-652 | Use of Known Kerberos Credentials
An adversary obtains (i.e. steals or purchases) legitimate Kerberos credentials (e.g. Kerberos service account userID/password or Kerberos Tickets) with the goal of achieving authenticated access to additional systems, applications, or services within the domain. |
