CAT II

Cookies exchanged between the web server and the client, such as session cookies, must have cookie properties set to prohibit client-side scripts from reading the cookie data.

From: Web Server Security Requirements Guide (V4R4)

Description

<VulnDiscussion>A cookie can be read by client-side scripts easily if cookie properties are not set properly. By allowing cookies to be read by the client-side scripts, information such as session identifiers could be compromised and used by an attacker who intercepts the cookie. Setting cookie properties (i.e. HttpOnly property) to disallow client-side scripts from reading cookies better protects the information inside the cookie.</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

Check Procedure

Review the web server documentation and deployed configuration to determine how to disable client-side scripts from reading cookies. If the web server is not configured to disallow client-side scripts from reading cookies, this is a finding.

Fix Text

Configure the web server to disallow client-side scripts the capability of reading cookie information.
