名稱: 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.
一般資訊
引入方式
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.

類別： Not Language-Specific (Undetermined)常見後果
| 範圍 | 影響 | 可能性 |
|---|---|---|
| Access Control Authentication | Bypass Protection Mechanism, Gain Privileges or Assume Identity 注意：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. |

| 參考資料 | 描述 |
|---|---|
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. |
漏洞對應備注
理由說明 : 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.備註 : 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-644 | Use of Captured Hashes (Pass The Hash)
An adversary obtains (i.e. steals or purchases) legitimate Windows domain credential hash values to access systems within the domain that leverage the Lan Man (LM) and/or NT Lan Man (NTLM) authentication protocols. |
| 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. |
