Website Security

Baidu

Secure cookies not used

When secure cookies are not used, there is an increased risk of third parties intercepting information contained in these cookies. The website configuration should be changed so that all 'Set-Cookie' headers include 'secure'.

Server information header exposed

Exposing information about the server version increases the ability of attackers to exploit certain vulnerabilities. The website configuration should be changed to prevent version information being revealed in the 'server' header.

X-Frame-Options is not deny or sameorigin

Browsers may display this website's content in frames. This can lead to clickjacking attacks.

CSP is not implemented

No valid Content Security Policy is implemented. This increases the risk of XSS and clickjacking attacks.

HttpOnly cookies not used

When HttpOnly cookies are not used, the cookies can be accessed on the client, which enables certain type of client-side attacks. The website configuration should be changed to enforce HttpOnly cookies.

X-Content-Type-Options is not nosniff

Browsers may interpret files as a different MIME type than what is specified in the Content-Type HTTP header. This can lead to MIME confusion attacks.

X-Powered-By header not exposed

Information about specific technology used on the server is obscured.

Referrer policy is not unsafe-url

The website's Referrer Policy is not configured to allow unsafe information to be sent in the referrer header.

ASP.NET version header not exposing specific ASP.net version

Ensuring the ASP.NET version header is not exposing a specific version makes it harder for attackers to exploit certain vulnerabilities.

ASP.NET version header not exposed

Ensuring the ASP.NET version header is not exposed makes it harder for attackers to exploit certain vulnerabilities.

Vulnerability Management

Baidu

Vulnerable to CVE-2014-3566 (POODLE)

The server supports SSLv3 and is therefore vulnerable to POODLE, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack.

Not vulnerable to CVE-2014-0160 (Heartbleed)

A bug in OpenSSL's implementation of the TLS heartbeat extension allows access to portions of memory on the targeted host e.g. cryptographic keys and passwords.

Not vulnerable to CVE-2015-0204 (FREAK)

The server does not offer RSA_EXPORT cipher suites, so clients are not vulnerable to the FREAK attack.

Not vulnerable to CVE-2015-4000 (Logjam)

The server is using strong Diffie-Hellman parameters and is not vulnerable to the Logjam attack.
