Details

According to the CVSS metrics, successful exploitation of this vulnerability could lead to minor loss of confidentiality (C:L), integrity (I:L) and availability (A:L). What does that mean for this vulnerability?
While we cannot rule out the impact to Confidentiality, Integrity, and Availability, the ability to exploit this vulnerability by itself is limited. An attacker can force a bad response to be cached into a regular URL by having multiple occurrences of the same variable in the query string. The impact depends on the business logic of the user application.
