CVE-2019-4563

Attackers may be able to get the cookie values by sending a http:// link to a user or by planting this link in a site the user goes to.

MEDIUM 5.3EPSS 0.93%

Does this matter?

Lower severity and a low EPSS score (0.93%). Track it; it rarely justifies an emergency change on its own.

Description

IBM Security Directory Server 6.4.0 does not set the secure attribute on authorization tokens or session cookies. Attackers may be able to get the cookie values by sending a http:// link to a user or by planting this link in a site the user goes to. The cookie will be sent to the insecure link and the attacker can then obtain the cookie value by snooping the traffic. IBM X-Force ID: 166624.
