事件日志 - 视图状态验证失败

发布于 2024-11-27 14:08:00 字数 7576 浏览 2 评论 0原文

最近我们将系统从.net 1.1 升级到.net 2.0。自从这样做以来，我们的事件日志中几乎每分钟都会出现以下错误。这很奇怪，但所有客户端 IP 或用户主机地址似乎都指向东欧国家，如俄罗斯或白俄罗斯。这是日志记录问题还是有人合法地试图进行黑客攻击或其他什么？ -

原文

Recently we upgraded our system from .net 1.1 to .net 2.0. Since doing so we have been getting errors in our event logs with the following error about every minute. It's weird but all client ips or user host address seems to be pointing to eastern European countries like Russia or Belarus. Is it a logging problem or is somebody legitimately trying to hack or something? -

前 2 个请求导致了视图状态验证/验证问题，原因如下：
PersistedState：[KEY1] - 这是一个验证错误。

另外 - 你说你已经从.Net 1.1升级到2.0
但是第三个请求中提供的视图状态以“dDw”开头 - 这是一个 .Net 1.1 视图状态（对于 .Net 2.0，它以“/wE”开头）

在用户代理中看到“TrackChecker”告诉我某种机器人/爬虫保存了您的页面的旧版本（当它们由.Net 1.1生成时 - 包括视图状态），现在它重新检查您的内容并提交无效的视图状态（出于显而易见的原因，.Net 1.1 视图状态将无法在 .Net 2.0 上进行验证）

The first 2 requests have caused the viewstate verification/validation issues because of this:
PersistedState: [KEY1] - this is a validation error straight away.

Also - you say you've upgraded from .Net 1.1 to 2.0
But the viewstate supplied in the 3rd request starts with "dDw" - this is a .Net 1.1 viewstate (for .Net 2.0 it starts with "/wE")

Seeing "TrackChecker" in the user agent tells me that some kind of bot/crawler saved older versions of your pages (when they were generated by .Net 1.1 - including the viewstate) and now it is re-checks your content and submits invalid viewstates (.Net 1.1 viewstates will fail validation on .Net 2.0 for obvious reasons)

我在我的一个网站上遇到了很多这样的 Viewstate 错误，通常是一个机器人试图碰运气发布一些邪恶的内容。

我怀疑这里也是如此 - 除非你有很多来自白俄罗斯的用户？

如果您修改日志以捕获查询字符串和其他请求参数，则可以为您提供一些线索，了解（所谓的）攻击者（或不幸的用户）试图实现什么目标。

I get a lot of these Viewstate errors on one of my sites, and it's normally a bot trying its luck to post something nefarious.

I suspect the same here - unless you have a lot of users from Belarus?

If you amend your logs to also capture the query string and other request params, that can give you some clues as to what the (alleged) attacker - or unfortunate user - was trying to achieve.
