Discuz点触验证码插件验证绕过+密码明文传输

简要描述： 部分DZ论坛启用点触验证码后验证码完全没有起作用。同时由于更改了登录逻辑，还会造成论坛登录密码明文传输。 详细说明： 由于点触验证码插件的验证逻辑有问题，启用验证码之后可以简单绕过。同时由于更改了登录逻辑，会将DZ原本的md5传输的密文变成明文传输。 漏洞证明： 将红框中的display: none; 去掉，然后可以看到多了一个登录按钮。 这个按钮是没有启用验证逻辑的。直接输入用户名密码就可以登录。同时这样登录的话POST提交的是正常的md5加密后的密码。 但是如果输入验证码提交的话，POST数据就变成了： 其中可以看到明文的密码字段。...

FreeBSD : FreeBSD -- OpenSSL multiple vulnerabilities (69bfc852-9bd0-11e2-a7be-8c705af55518)

A flaw in the OpenSSL handling of OCSP response verification could be exploited to cause a denial of service attack. OpenSSL has a weakness in the handling of CBC ciphersuites in SSL, TLS and DTLS. The weakness could reveal plaintext in a timing attack. %NASLMINLEVEL 70300 C Tenable Network...

RC4 encryption protocol is vulnerable to certain brute force attacks – Opera Security Advisories

Weaknesses in the RC4 encryption protocol have been found, allowing an attacker to deduce the plaintext. If the same message is encrypted many millions of times, statistical methods can be used to extract valuable information, such as cookies. Due to the time this amount of requests takes, this i...
