所有,我真的可以在这里使用一些帮助。我的最终目标是能够使用perl读取xml文件,并将其插入数据库以跟踪CVE。在这个阶段,如果我只能从我的代码中的XML文件中引用变量,我相信我可以将它插入到数据库中。现在我所要做的就是把它打印到屏幕上,但我无法使它正常工作。使用Perl XML解析XML与命名空间::简单
这是我简单的代码和XML文件。
希望有人能让我去这里。
的Perl --start代码 -
#!/usr/bin/perl
# use module
use XML::Simple;
use Data::Dumper;
# create object
xml = new XML::Simple (KeyAttr=>[]);
# read XML file
#$data = $xml->XMLin("tms.xml");
# print output - used this to see if it was even reading it
#print Dumper($data);
# access XML data
print "Here is the BugTrackID: $data->{'x:BugTraqID'}\n";

<x:ShortSummary><![CDATA[Sonar is prone to multiple cross-site scripting vulnerabilities.]]></x:ShortSummary>
<x:Impact>An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookie-based authentication credentials and launch other attacks.</x:Impact>
<x:TechnicalDescription><![CDATA[Sonar is the open source platform for code quality inspection.
The application is prone to multiple cross-site scripting vulnerabilities because it fails to sanitize user-supplied input submitted to the following scripts and parameters:
'index.php ' : 'search', 'assignee_login',
'author_login'
'sources.php' : 'resource'
An attacker may leverage these issues to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site. This may allow the attacker to steal cookie-based authentication credentials and launch other attacks.
Sonar 3.4.1 is vulnerable; other versions may also be affected.]]>
</x:TechnicalDescription>
<x:AttackScenario><![CDATA[1. An attacker scans for and locates a site running the affected application.
2. The attacker crafts a URI link that includes malicious script code designed to leverage one of these issues.
3. The attacker uses email or other means to distribute the malicious link and entices an unsuspecting user to follow it.
4. When the user follows the link, the attacker-specified script code runs in their browser in the context of the affected site.
A successful exploit may let the attacker steal cookie-based authentication credentials and launch other attacks.]]></x:AttackScenario>
<x:Exploit><![CDATA[Attackers can exploit these issues by enticing an unsuspecting victim into following a malicious URI.
The following example URIs are available:
http://www.example.com/dependencies/index? search="&gt;&lt;script&gt;alert(/devilteam.pl/)&lt;/script&gt;
http://www.example.com/dashboard/index/41730? did=4&amp;period=3"&gt;&lt;script&gt;alert(/devilteam.pl/)&lt;/script&am p;gt;

你有什么问题? – ikegami 2013-02-16 03:42:20
你提到了namesapces。 XML :: Simple知道关于namespsaces和前缀的事情。它只是假定前缀是节点名称的一部分。 “XML :: Simple,您可以使用的最复杂的XML解析器。” – ikegami 2013-02-16 03:43:34
我无法让它输出任何值。具体来说,我只是试图让它从xml文件打印bugtraqid值。它回来了。 – 2013-02-16 03:45:46
