java - 安全:090759 in weblogic managed logs

Question

我在 weblogic 托管日志文件中收到以下错误，并且无法跟踪客户端 IP 或 URL 的来源。看起来服务器上正在发生一些 SQL 注入(inject)，因此请提供详细信息以防止它并获取有关它的更多详细信息。

Answer 1

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。也许有人只是用经典的键盘粉碎来测试您的网站，并且碰巧以这样的方式粉碎了按键，从而为用户 ID 输入了撇号。

Weblogic 似乎正在检查输入的用户输入是否包含“无效”字符，这意味着用户 ID 受到了 sql 注入(inject)攻击。但我的理解是他们正在使用 PreparedStatement s 这使得验证字符输入有点奇怪。这可能只是对后端 LDAP 中有效用户 ID 的限制。

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.+(@./*

这个答案的大部分内容都是基于这个forum discussion .

我检查了metalink.oracle.com，但没有找到论坛中列出的SR。
