Java 安全性：weblogic托管日志中的090759

我在weblogic管理的日志文件中遇到以下错误，无法跟踪客户端IP或URL的来源。看起来有些SQL注入正在服务器上发生，所以请提供详细信息以防止它，并获取更多有关它的详细信息

这是weblogic验证用户ID输入作为其登录实现的一部分。我相信Oracle的OID不允许在用户ID中使用撇号。也许有人只是简单地用经典的键盘扣杀来测试你的网站，碰巧扣杀键的方式是在用户ID中输入一个撇号

Weblogic似乎正在检查输入的用户输入是否包含“无效”字符，这可能意味着使用用户ID进行sql注入攻击。但据我所知，他们使用的是s，这使得验证字符输入有点奇怪。这很可能只是一个约束，限制了如何在后端LDAP中创建有效的用户ID

在您的情况下，用户输入了以下内容：

@^Y@.@o*.2,./2|pq{jvk@-1('@lvo)&1,.1(.1.+(@./*

这个答案大部分是基于这个

我确实查看了metalink.oracle.com，但没有找到论坛中列出的SR。
是否有任何好友需要修复此问题的详细信息我检查了，也没有找到提到的SR。我已提出SR 3-931575181。
