在spring framework 3.2.4 app上使用OWASP_CSRFTOKEN将session.getAttribute（）的键为null

我将OWASP.CsrfGuard.jar添加到我的spring 3.2.4应用程序中以防止CSRF攻击（CSRF是一种攻击，迫使最终用户在他/她当前经过身份验证的Web应用程序上执行不需要的操作。最常用的例子是＆＃34;有人欺骗您点击链接以获取您登录的银行会话，然后在未经您同意/知情的情况下从您的银行帐户中提取资金）

这是我的Owasp.CsrfGuard.properties：

# The default behavior of CSRFGuard is to protect all pages. Pages marked as unprotected will not be protected.
# If the Protect property is enabled, this behavior is reversed. Pages must be marked as protected to be protected.

# Token Name
#
# The token name property (org.owasp.csrfguard.TokenName) defines the name of the HTTP parameter
# to contain the value of the OWASP CSRFGuard token for each request. The following configuration
# snippet sets the CSRFGuard token parameter name to the value OWASP_CSRFTOKEN:
#
org.owasp.csrfguard.TokenName=OWASP_CSRFTOKEN_REQUEST

# Session Key
#
# The session key property (org.owasp.csrfguard.SessionKey) defines the string literal used to save
# and lookup the CSRFGuard token from the session. This value is used by the filter and the tag
# libraries to retrieve and set the token value in the session. Developers can use this key to
# programmatically lookup the token within their own code. The following configuration snippet sets
# the session key to the value OWASP_CSRFTOKEN:
#
org.owasp.csrfguard.SessionKey=OWASP_CSRFTOKEN

# Token Length
#
# The token length property (org.owasp.csrfguard.TokenLength) defines the number of characters that
# should be found within the CSRFGuard token. Note that characters are delimited by dashes (-) in groups
# of four. For cosmetic reasons, users are encourage to ensure the token length is divisible by four.
# The following configuration snippet sets the token length property to 32 characters:
#
# org.owasp.csrfguard.TokenLength=32
org.owasp.csrfguard.TokenLength=32

# Pseudo-random Number Generator
#
# The pseudo-random number generator property (org.owasp.csrfguard.PRNG) defines what PRNG should be used
# to generate the OWASP CSRFGuard token. Always ensure this value references a cryptographically strong
# pseudo-random number generator algorithm. The following configuration snippet sets the pseudo-random number
# generator to SHA1PRNG:
#
# org.owasp.csrfguard.PRNG=SHA1PRNG
org.owasp.csrfguard.PRNG=SHA1PRNG

# Pseudo-random Number Generator Provider

# The pseudo-random number generator provider property (org.owasp.csrfguard.PRNG.Provider) defines which
# provider's implementation of org.owasp.csrfguard.PRNG we should utilize. The following configuration
# snippet instructs the JVM to leverage SUN's implementation of the algorithm denoted by the
# org.owasp.csrfguard.PRNG property:

# org.owasp.csrfguard.PRNG.Provider=SUN
org.owasp.csrfguard.PRNG.Provider=SUN

# If not specifying the print config option in the web.xml, you can specify it here, to print the config
# on startup
org.owasp.csrfguard.Config.Print=true



# seconds between checking to see if the config files are updated
org.owasp.csrfguard.configOverlay.secondsBetweenUpdateChecks = 60

然后我在JSP中包含这个标记：

<input type="hidden" name="<csrf:tokenname />" value="<csrf:tokenvalue />" />

但结果是：

答案 0 :(得分：1)

WebLogic似乎并不喜欢Sun的SHA1PRNG实现。在我们的项目中，我们发现为了让CSRF Guard在WebLogic上工作（即避免你得到的确切错误），我们需要更换

accessories.Except(foo);

与

org.owasp.csrfguard.PRNG=SHA1PRNG
org.owasp.csrfguard.PRNG.Provider=SUN

我不确定这是否意味着您需要使用IBM JDK才能将WebLogic与CSRF Guard一起使用，或者如果您可以使用其他PRNG来使其工作。

请注意，这似乎特定于WebLogic，因此您可能会更好地使用其他Java Web应用程序服务器。
