1. 引言
微软解决大量CVE补丁更新的检测时候,采取的思路不是根据MD5对单个漏洞文件(.dll、.sys)进行漏洞检测,而是采取基线检测的思路,对目标的.dll、.sys文件进行版本检测,如果当前版本不是最新的,则报告对应的可能存在的疑似漏洞
0x1: 技术方案
1. 识别WEB路径 1) 进程启动参数 2) 解析WEB容器配置文件 2. 定位CMS类型 1) 从WEB根目录进行递归查找 2) 根据相对路径、文本正则特征进行CMS类型定位 3) 所有的规则(SEARCHPATHRULE)是逻辑与的关系,必须同时成立后,才能100%定位到该CMS类型 /* 需要注意的是: 有可能出现同一个WEB目录下同时存在同一类、但不同版本的CMS,在搜索的时候需要根据这些CMS的相对根目录分别进行正则匹配,最后统一统计结果,例如 1. D:wampwwwdedecms5.5 1) D:wampwwwdedecms5.5plusmytag_js.php: 路径命中、内容正则匹配成功 2) D:wampwwwdedecms5.5plusad_js.php: 未命中 2. D:wampwwwdedecms5.7 1) D:wampwwwdedecms5.7plusmytag_js.php: 路径命中、内容正则匹配成功 2) D:wampwwwdedecms5.7plusad_js.php: 路径命中、内容正则匹配成功 则最后的结果为: D:wampwwwdedecms5.7 */ 4. 识别CMS版本 将上一步得到的CMS目录根目录,和规则库中的版本标的文件的相对路径进行拼接,利用正则匹配从标的文件中获取版本信息数据 /* 对于CMS版本的识别,通用的思路如下 1. 寻找每个版本100%一定都会变化的"标的文件",计算它的MD5值,和事先计算好的最新版的"标的文件"的MD5进行对比 2. 根据相对路径寻找一个"版本信息文件",此文件中明文保存着当前的版本信息 */ 5. 计算当前获取的版本信息是否"小于"规则库中的版本信息(这里的小于需要在格式转换的基础上进行比较) 6. 特征的匹配、版本信息的提取采取正则规则进行,在正则规则中使用了一些非捕获分组、前后环视控制符,在提取结果的时候需要提取"第一个捕获子组匹配到的文本"
权衡之下,在判断版本的方案中,如果采用方案1的话如果规则库不及时更新的话,可能会造成大规模误报(用户本机的CMS版本高于规则中的版本,但是因为MD5不同也被报出来了),所以采用方案2是相对较合理的方案,这种方案要求规则制定的时候需要case by case地调研不同CMS标识版本信息的路径文件

0x3: DISCUZ
Discuz的版本存在2个分支,Discuz(number)是老的分支现在已经不维护了,Discuz-X是新的分支,所以原则上如果检测到当前CMS为数字系列的,都一律报告存在低版本风险

0x1: 版本比较
版本比较需要考虑到多种情况
1. 获取当前版本失败、获取的当前版本和配置里的基线配置参数格式不一致,遵循"宁可漏报不能误报"的原则,选择忽略 2. 格式相同、且长度不相同 1) 点分格式: 逐段判断 2) 纯数字形式: 解析为年-月-日后逐段判断 3. 格式相同,长度不同 将长度段的版本号补全,例如: 3.5.7 compare 3.5 => 3.5.7 compare 3.5.0
