Acunetix 360 identified a cookie not marked as secure, and transmitted over HTTPS.
This means the cookie could potentially be stolen by an attacker who can successfully intercept and decrypt the traffic, or following a successful man-in-the-middle attack.
This cookie will be transmitted over a HTTP connection, therefore if this cookie is important (such as a session cookie), an attacker might intercept it and hijack a victim's session. If the attacker can carry out a man-in-the-middle attack, he/she can force the victim to make an HTTP request to steal the cookie.
Actions To Take
- See the remedy for solution.
- Mark all cookies used within the application as secure. (If the cookie is not related to authentication or does not carry any personal information, you do not have to mark it as secure.)
Mark all cookies used within the application as secure.
Required Skills for Successful Exploitation
To exploit this issue, the attacker needs to be able to intercept traffic. This generally requires local access to the web server or to the victim's network. Attackers need to be understand layer 2, have physical access to systems either as waypoints for the traffic, or have locally gained access to to a system between the victim and the web server.
